- Swar (स्वर) — Vowels
- Independent sounds produced without obstruction in the vocal tract. Hindi has 11 vowels, further divided into Hrasva (short), Deergha (long), and Pluta (prolated).
- Vyanjan (व्यंजन) — Consonants
- Sounds produced with obstruction or contact in the vocal tract. Consonants need vowels to be pronounced; the inherent vowel is 'अ'.
- Vargiiya Vyanjan (वर्गीय व्यंजन)
- 25 structured consonants arranged in 5 groups (वर्ग) of 5 letters each — क-वर्ग, च-वर्ग, ट-वर्ग, त-वर्ग, प-वर्ग. Each group follows a pattern: voiceless-unaspirated, voiceless-aspirated, voiced-unaspirated, voiced-aspirated, nasal.

- Devanagari script follows a phonetic principle
- Each letter represents one distinct sound, making Hindi spelling largely phonetic and predictable once you know the Varnamala.
Sandhi (संधि) — General Hindi (सामान्य हिंदी) · 6 cards
- Sandhi Definition
- The phonetic modification that occurs when two sounds meet at the junction of two words or word parts. The resulting combined form is the sandhi roop (संधि रूप), and separating it back is sandhi vichchhed (संधि विच्छेद) or vigrah (विग्रह).
- Swar Sandhi (स्वर संधि)
- Occurs when a vowel at the end of one word meets a vowel at the beginning of the next. Five subtypes: Deergh (दीर्घ), Guna (गुण), Vriddhi (वृद्धि), Yan (यण), and Ayadi (अयादि).
- Vyanjan Sandhi (व्यंजन संधि)
- Happens when a consonant at the end of one word meets a vowel or consonant at the start of the next, or when certain consonant clusters form. Rules involve doubling, substitution, or insertion of sounds.
- Visarg Sandhi (विसर्ग संधि)
- The visarga (ः) symbol undergoes transformation based on the following sound — it may become 'स', 'र', 'ओ', or disappear entirely. Context and the nature of the following consonant or vowel determine the change.
- Sandhi Purpose
- Sandhi ensures smooth pronunciation (euphony) and reflects the natural flow of spoken language. It is not arbitrary but follows systematic phonetic principles.
- Exam Strategy
- Learn the core subtypes and their signature examples. Practice vigrah (breaking sandhi forms) and sandhi formation (combining words). Questions may give you a combined word and ask which type of sandhi it is, or ask you to identify the correct components.
Samas (समास) — General Hindi (सामान्य हिंदी) · 4 cards

Upsarg & Pratyay (उपसर्ग-प्रत्यय) — General Hindi (सामान्य हिंदी) · 8 cards
- Upsarg (उपसर्ग)
- is a prefix added to the beginning of a root word that alters or enhances its meaning. Upsargs do not have independent meaning but modify the root word contextually. Example: हार (defeat) becomes प्रहार (attack) when "प्र" is added.
- Pratyay (प्रत्यय)
- is a suffix added to the end of a root word, creating new nouns, adjectives or adverbs. Unlike upsargs, pratyays often denote gender, case, tense or abstract qualities. Example: मीठा (sweet) becomes मिठाई (sweetness/sweet dish) when "आई" is added.
- Tatsam vs Tadbhav
- Most Hindi upsargs originate from Sanskrit (tatsam) like अ, प्र, वि, सम्, अधि, while some are Tadbhav (Hindi-evolved) like अन, कु. Understanding the Sanskrit origin helps predict meanings.
- Pratyay types
- Two major categories — Krit Pratyay (कृत प्रत्यय) attached to verb roots (लिख + आवट = लिखावट), and Taddhit Pratyay (तद्धित प्रत्यय) attached to nouns/adjectives (मानव + ता = मानवता).
- Multiple affixes
- A single word can contain multiple upsargs or pratyays. Example: अप्रत्याशित = अ (negation) + प्रति (towards) + आशित (hoped), meaning "unexpected."
- Meaning transformation patterns
- Upsargs often indicate direction (उप = near, अव = down), negation (अ, नि), intensity (सु, अति), or relation (सह, अनु). Pratyays indicate state (आई, पन), action (आवट, आहट), or possession (वान, मान).
- Gender and number markers
- Pratyays like ई, इन, आइन create feminine forms (लड़का → लड़की), while others like त्व, ता create abstract nouns (मनुष्य → मनुष्यत्व).
- Exam trap
- Words that look like they contain an upsarg/pratyay but don't. Example: "प्रेम" is not प्र + एम; it's an independent word. Always verify that removal of the prefix/suffix leaves a meaningful root.

- True synonyms are interchangeable in most contexts, though some may carry slightly different connotations or formality levels (e.g., जल and पानी both mean water but जल is more formal).
- Sanskrit origins
- Many Hindi synonyms derive from Sanskrit (tatsam words) and coexist with colloquial variants (tadbhav), creating rich synonym sets.
- Exam pattern
- Questions present a word in bold or underlined, asking for its paryayvachi from options; sometimes a sentence requires filling in the most appropriate synonym.
- Elimination strategy
- When unsure, eliminate options that are antonyms or unrelated words first; narrow down between close synonyms by considering the sentence context if provided.
- Word families
- Grouping synonyms by theme (nature words, emotion words, action words) aids faster memorisation and recall during the exam.
- Common confusions
- Words that sound similar but mean different things (श्रवण/श्रावण) or words that are related but not true synonyms (पुत्र/पुत्री — son/daughter) appear as distractors.
Vilom (विलोम शब्द) — General Hindi (सामान्य हिंदी) · 6 cards
- Vilom shabd definition
- A vilom shabd expresses the opposite or contrary meaning of another word. Example: सत्य (truth) ↔ असत्य (falsehood).
- Formation patterns
- Many antonyms are formed by adding prefixes like अ-, अन-, निर-, दुर-, कु- to create negation or opposition. Example: योग्य → अयोग्य, आवश्यक → अनावश्यक.
- True opposites vs. negative forms
- While adding 'अ' creates a negative (सुंदर → असुंदर), the true vilom may be a different word (सुंदर → कुरूप). The exam may test both forms.
- Contextual opposites
- Some words have different antonyms depending on context. For instance, प्रकाश can mean "light" (opposite: अंधकार) or "appearance" (opposite: अप्रकट).
- Gender and number
- Antonym pairs must maintain grammatical agreement. If the original word is masculine, its opposite should also be masculine in the same context.
- Common prefixes for opposition
- अ/अन (negation), वि (reversal), दुर/दुष (bad), निर/निस (without), कु (bad), सु (good), उत्/उद् (up), अव (down).
Anekarthi Shabd (अनेकार्थी शब्द) — General Hindi (सामान्य हिंदी) · 6 cards
- Context determines meaning
- The same word can function as a noun in one sentence and convey an entirely different concept in another based on surrounding words, grammatical structure, and subject matter.
- Single spelling, multiple senses
- Unlike homophones (which sound same but spell differently), anekarthi words maintain identical spelling and pronunciation across all meanings — only semantic interpretation changes.
- Common exam pattern
- Questions typically present 3-4 meanings and ask which meanings are valid for a given word, or provide sentences using the word differently and test comprehension.
- Domain-specific meanings
- Many anekarthi words have everyday meanings plus specialized meanings in literature, philosophy, religion, or technical contexts (e.g., "अर्थ" means both "meaning" and "wealth").
- No etymological connection required
- The multiple meanings may or may not be historically related; what matters for exam purposes is recognition and correct contextual application.
- Elimination strategy works well
- When unsure, eliminate meanings that clearly don't fit the sentence structure or subject matter, then choose from remaining options.
Ling, Vachan, Karak (लिंग, वचन, कारक) — General Hindi (सामान्य हिंदी) · 12 cards
- Ling (लिंग)
- refers to grammatical gender in Hindi. Every noun is either masculine (पुल्लिंग) or feminine (स्त्रीलिंग). There is no neuter gender in Hindi, unlike Sanskrit or English. Gender determines the form of adjectives, verbs, and pronouns used with that noun.
- Vachan (वचन)
- denotes number — singular (एकवचन) or plural (बहुवचन). Hindi plurals are formed by changing noun endings or adding suffixes. Some nouns remain unchanged in plural form, and the context or verb reveals number.
- Karak (कारक)
- is the grammatical case that shows the relationship of a noun or pronoun to other words in a sentence. Hindi has eight karaks: karta, karm, karan, sampradaan, apaadaan, sambandh, adhikaran, and sambodhan. Each karak is marked by specific postpositions called vibhakti chinh (विभक्ति चिह्न).
- Ling-Vachan agreement
- is critical: adjectives, verbs, and pronouns must agree in gender and number with the noun they modify or refer to. Disagreement is a common source of grammatical errors tested in exams.
- कर्ता
- Meaning: Doer/Subject · Vibhakti Chinh: ने (with transitive verbs in perfective past tenses) · Example: राम ने खाया
- कर्म
- Meaning: Object · Vibhakti Chinh: को · Example: उसने रोटी को खाया
- करण
- Meaning: Instrument · Vibhakti Chinh: से, द्वारा · Example: चाकू से काटो
- सम्प्रदान
- Meaning: Recipient · Vibhakti Chinh: के लिए, को · Example: गरीबों के लिए दान
- अपादान
- Meaning: Separation · Vibhakti Chinh: से (ablative) · Example: पेड़ से पत्ता गिरा
- सम्बन्ध
- Meaning: Possession · Vibhakti Chinh: का, की, के · Example: राम की किताब
- अधिकरण
- Meaning: Location · Vibhakti Chinh: में, पर · Example: घर में, मेज़ पर
- सम्बोधन
- Meaning: Address · Vibhakti Chinh: हे, ओ · Example: हे भगवान, ओ मित्र
Sangya & Sarvanam (संज्ञा-सर्वनाम) — General Hindi (सामान्य हिंदी) · 3 cards
- Sangya (Noun)
- is any word that names a person, place, thing, quality, state, or action. It answers "कौन?" (who?) or "क्या?" (what?). Example: राम, दिल्ली, पुस्तक, सुंदरता।
- Sarvanam (Pronoun)
- replaces a noun to avoid repetition and maintain sentence flow. It refers back to a previously mentioned noun (antecedent). Example: वह, मैं, कोई, जो।
- Purush-vachak sarvanam
- has three persons: Uttam Purush (first person — मैं, हम), Madhyam Purush (second person — तू, तुम, आप), Anya Purush (third person — वह, वे, यह, ये).
Kriya & Visheshan (क्रिया-विशेषण) — General Hindi (सामान्य हिंदी) · 8 cards
- Kriya (क्रिया)
- is any word that shows action (गया, खाया), state (है, था), or occurrence (हुआ). Without kriya, a Hindi sentence is incomplete.
- Kriya ke bhed
- Sakarmak kriya (सकर्मक — transitive, requires object: "मैंने खाना खाया") and Akarmak kriya (अकर्मक — intransitive, no object needed: "वह सोता है").
- Visheshan (विशेषण)
- qualifies or describes a noun (visheshya/विशेष्य). Example: "अच्छा लड़का" — 'अच्छा' is visheshan, 'लड़का' is visheshya.
- Four types of Visheshan
- Gunvachak (qualitative: सुंदर, बुद्धिमान), Sankhyavachak (numerical: दो, कई), Parimāṇvachak (quantitative: थोड़ा, अधिक), Sārvanamik (pronominal: यह, वह, कोई).
- Kriya-visheshan (क्रिया-विशेषण)
- or adverbs modify verbs, adjectives, or other adverbs. They answer how, when, where, and to what extent. Example: "वह तेज़ दौड़ता है" — 'तेज़' modifies the verb 'दौड़ता'.
- Four main types of Kriya-visheshan
- Kālvāchak (time: आज, कल), Sthānvāchak (place: यहाँ, वहाँ), Rītivāchak (manner: धीरे, अचानक), Parimāṇvāchak (degree: बहुत, थोड़ा).
- Agreement rules
- Visheshan must agree with the visheshya in gender (ling) and number (vachan). Example: "सुंदर लड़की" (feminine singular) vs "सुंदर लड़के" (masculine plural).
- Verb conjugation
- Kriya changes form based on subject's gender, number, tense, and respect level. Recognizing root verb (dhatu) and auxiliary verbs (सहायक क्रिया) is essential for identifying tense and voice.
Kaal & Vachya (काल-वाच्य) — General Hindi (सामान्य हिंदी) · 8 cards
- Kaal (Tense)
- indicates the time of action and has three main types: Vartman (present), Bhoot (past) and Bhavishya (future). Each has sub-types based on action completion, continuity or habitual nature.
- Vartman Kaal (Present Tense)
- has three forms: Samanya (simple present — रोहन पढ़ता है), Apurna (present continuous — रोहन पढ़ रहा है) and Sandigdha (doubtful present — रोहन पढ़ता होगा).
- Bhoot Kaal (Past Tense)
- includes six sub-types: Samanya (simple past — मैंने पढ़ा), Apurna (past continuous — मैं पढ़ रहा था), Purna (past perfect — मैंने पढ़ा था), Sandigdha (doubtful past — मैंने पढ़ा होगा), Aasanna (near past — मैंने पढ़ा है) and Hetuhetumat (past conditional).
- Bhavishya Kaal (Future Tense)
- has three forms: Samanya (simple future — मैं पढ़ूँगा), Sambhavya (probable future — मैं पढ़ूँ) and Hetuhetumat (conditional future — यदि पढ़ूँ तो...).
- Vachya (Voice)
- defines sentence structure based on emphasis: Kartri Vachya (active voice) emphasizes the doer, Karm Vachya (passive voice) emphasizes the action or object, and Bhav Vachya (impersonal voice) emphasizes the state or condition.
- Kartri Vachya
- keeps the subject as the doer with verb agreeing in gender/number with the subject (राम खाना खाता है). The doer is the focus and appears in nominative case.
- Karm Vachya
- transforms the object into the grammatical subject; the verb agrees with the object, and the doer takes से/के द्वारा (राम द्वारा खाना खाया जाता है). Emphasis shifts from doer to the action or receiver.
- Bhav Vachya
- is used for intransitive verbs or when action cannot be performed, focusing on the state itself (मुझसे चला नहीं जाता). The doer takes से and the verb remains third-person singular masculine.
Muhavare (मुहावरे) — General Hindi (सामान्य हिंदी) · 7 cards
- Idioms are frozen expressions
- The exact wording matters. "आँखों का तारा" (pupil of the eye) means beloved, but you cannot change it to "नेत्रों का तारा" in the idiom, even though both mean eyes in Hindi.
- Figurative vs. literal meaning
- Every idiom has a surface (literal) meaning and a deeper (figurative) meaning. Exam questions test whether you understand the figurative sense used in real communication.
- Body-part idioms dominate
- A large category involves body parts — हाथ (hand), आँख (eye), मुँह (mouth), कान (ear), सिर (head) — reflecting how physical gestures became linguistic metaphors.
- Cultural context matters
- Many idioms derive from village life, farming, animals, and traditional occupations. Understanding these origins helps retention — "खेत रहना" (to remain in the field) means to die because fields were battlegrounds.
- One idiom, multiple contexts
- Some idioms like "पत्थर की लकीर" (etched in stone) can mean both permanence and unchangeability depending on sentence context. Practice identifying context from surrounding words.
- Beware of similar-sounding idioms
- "अपना उल्लू सीधा करना" (straighten one's owl = serve selfish purpose) vs "उल्लू बनाना" (make an owl = make a fool) — different meanings despite sharing "उल्लू".
- Questions test application, not just definitions
- Besides "What does X mean?", expect: "Choose the idiom that fits this blank" or "Which sentence correctly uses this idiom?"
Ras, Chhand, Alankar — General Hindi (सामान्य हिंदी) · 3 cards
- Ras (रस)
- is the dominant emotional flavor or sentiment evoked in the reader by a poem. Nine classical rasas exist, each arising from specific sthaayi bhaav (permanent emotions). Ras is the ultimate aesthetic experience in poetry — "वाक्यं रसात्मकं काव्यम्" (A sentence imbued with ras is poetry).
- Chhand (छंद)
- refers to the metre or rhythmic structure of verses, governed by syllable count (matra), syllable type (laghu/guru) and pause patterns (yati). Chhands are broadly classified into Matra-vritt (matra-count-based) and Varn-vritt (varna/syllable-count-based).
- Alankar (अलंकार)
- are figures of speech or ornamental devices that enhance the beauty and expressiveness of poetry. They are divided into Shabdalankar (sound-based) and Arthalankar (meaning-based). Alankars make language vivid, memorable and impactful.
Shabd Rachna (शब्द रचना) — General Hindi (सामान्य हिंदी) · 8 cards
- Mool Shabd (मूल शब्द)
- The root or base word from which other words are derived. Example: "लिख" (likh) is the root for "लिखना", "लिखाई", "लेखक".
- Dhatu (धातु)
- The verbal root that carries the core action meaning. Most verbs and verb-derived nouns come from dhatus. Example: "गम्" (gam) → गमन, गति, आगमन.
- Prakriya (प्रक्रिया)
- The morphological process of word formation including adding prefixes (upsarg), suffixes (pratyay), and compounding (samas).
- Yaugik Shabd (यौगिक शब्द)
- Derived words whose meaning can be understood by analyzing their components. Example: "विद्यालय" = विद्या + आलय (place of learning).
- Roodh Shabd (रूढ़ शब्द)
- Words whose meaning cannot be derived from their parts; they're conventionally accepted. Example: "घर", "कल" — split into parts, they give no meaning. ("पंकज", literally "born in mud" but used only for "lotus", is Yog-Roodh.)
- Yog-Roodh Shabd (योग-रूढ़ शब्द)
- Originally yaugik words that acquired a specific conventional meaning. Example: "लम्बोदर" (long-bellied) specifically refers to Lord Ganesha.
- Vikari Shabd (विकारी शब्द)
- Words formed by inflection or modification of base forms through case endings, tense markers, or grammatical changes.
- Sanrachnatmak Pad (संरचनात्मक पद)
- Structural units including stems, roots, and bound morphemes that combine to create complete words.
Vakya Shuddhi (वाक्य शुद्धि) — General Hindi (सामान्य हिंदी) · 8 cards
- Ling Sambandhit Ashuddhiyan (लिंग संबंधित अशुद्धियाँ)
- Gender errors occur when adjectives, verbs or pronouns don't match the gender of the noun. Example: "लड़का सुंदर है" (correct) vs "लड़का सुंदरी है" (incorrect — 'सुंदरी' is feminine).
- Vachan Sambandhit Ashuddhiyan (वचन संबंधित अशुद्धियाँ)
- Number errors arise when singular-plural agreement fails between subject and verb/adjective. Example: "लड़के आया" (incorrect) vs "लड़के आए" (correct).
- Karak Sambandhit Ashuddhiyan (कारक संबंधित अशुद्धियाँ)
- Case marker errors involve incorrect use of postpositions (ने, को, से, में, पर). Example: "राम को किताब पढ़ता है" (incorrect) vs "राम किताब पढ़ता है" (correct).
- Kaal Sambandhit Ashuddhiyan (काल संबंधित अशुद्धियाँ)
- Tense inconsistencies occur when verbs don't align with time context. Example: "वह कल आया था और मुझसे मिलता है" (mixed tense, incorrect).
- Kriya Sambandhit Ashuddhiyan (क्रिया संबंधित अशुद्धियाँ)
- Verb errors include incorrect auxiliary verbs, agreement failures, and wrong verb forms. Example: "मैं जाता हूँ" (correct) vs "मैं जाता है" (incorrect).
- Shabd Sambandhit Ashuddhiyan (शब्द संबंधित अशुद्धियाँ)
- Word choice errors involve using wrong words that sound similar or using non-standard Hindi words. Example: "उसकी आवाज़ सुनकर मुझे अच्छा लगा" (correct) vs "उसकी आवाज़ सुनके..." (colloquial, incorrect in written Hindi).
- Avyay aur Yogjak Sambandhit Ashuddhiyan (अव्यय और योजक संबंधित अशुद्धियाँ)
- Errors in conjunctions and indeclinable words. Example: "वह पढ़ता है और खेलता है" (correct) vs "वह पढ़ता है तथा खेलता है" (overly formal in speech context).
- Muhavare aur Lokokti Sambandhit Ashuddhiyan (मुहावरे और लोकोक्ति संबंधित अशुद्धियाँ)
- Idiomatic errors occur when phrases are partially remembered or mixed. Example: "हाथों-हाथ लेना" (correct) vs "हाथ-हाथ लेना" (incorrect form).

Simplification — Numerical & Mental Ability · 6 cards
- BODMAS/BODMAS Rule
- Operations must follow the strict order — Brackets first, then Orders (powers/roots), then Division and Multiplication (left to right), finally Addition and Subtraction (left to right). Violating this order is the most common error.
- Fraction Operations
- For addition/subtraction, convert to common denominator; for multiplication, multiply numerators and denominators directly; for division, multiply by the reciprocal. Mixed fractions must be converted to improper fractions before operations.
- Decimal Handling
- Align decimal points for addition/subtraction. For multiplication, count total decimal places in factors and place that many in the product. For division, shift decimal points to make divisor a whole number.
- Square and Cube Roots
- Perfect squares (1, 4, 9, 16, 25...144, 169, 196, 225, 256, 289, 324, 361, 400) and perfect cubes (1, 8, 27, 64, 125, 216, 343, 512, 729, 1000) must be memorized. Use factorization or digit methods for non-perfect roots.
- Reciprocal and Negative Signs
- Division by a fraction equals multiplication by its reciprocal. Double negatives make positive; a negative times positive stays negative. Track sign changes carefully through multi-step problems.
- Approximation Techniques
- In exams, don't calculate exact decimals when options differ significantly. Round strategically—but only after all operations inside brackets are complete.
Percentage — Numerical & Mental Ability · 8 cards
- Definition
- Percentage expresses a number as a fraction of 100. If a quantity is x out of y, then percentage = (x/y) × 100%.
- Conversion clarity
- To convert percentage to fraction, divide by 100. To convert fraction to percentage, multiply by 100. For example, 3/4 = (3/4) × 100 = 75%.
- Percentage increase/decrease
- If a value changes from A to B, percentage change = [(B - A)/A] × 100%. Positive result means increase, negative means decrease.
- Successive percentage changes
- When two percentage changes apply consecutively, the net effect is NOT their simple sum. Use the formula: Net% = a + b + (ab/100), where a and b are the two percentage changes.
- Percentage of a percentage
- "x% of y%" means (x/100) × (y/100) × original value. This is common in population or consumption problems.
- Reversing percentage changes
- If a value increases by x%, to bring it back to original, it must decrease by [x/(100+x)] × 100%, not by x%.
- Expressing one quantity as percentage of another
- If A is to be expressed as percentage of B, calculate (A/B) × 100%. Order matters — "A as % of B" differs from "B as % of A".
- Base value identification
- Always identify what is the base (denominator) for percentage calculation. "Marks increased by 20%" means 20% of original marks, not 20% of new marks.
Average — Numerical & Mental Ability · 8 cards
- Average
- is the sum of all observations divided by the number of observations. It represents the central or typical value of a dataset.
- Formula relationship
- Average = Total Sum / Number of Items, which rearranges to Total Sum = Average × Number of Items. This second form is critical for solving most exam problems.
- Weighted Average
- applies when different groups have different counts. The combined average is NOT the simple average of the two averages; you must account for the weight (count) of each group.
- Effect of Adding/Removing
- When a new element is added or an old one removed, the average changes. Calculate the new total sum, then divide by the new count.
- Replacement Impact
- When one element replaces another, the change in average reveals the difference between the new and old elements.
- Age Problems
- Average age questions often involve time shifts (e.g., "5 years ago" or "after 3 years"). Remember that when n people age by t years, the total age increases by n×t.
- Shortcut for Consecutive Numbers
- The average of consecutive integers is the middle number (for odd count) or the average of the two middle numbers (for even count).
- Zero-Sum Thinking
- Deviations from the average cancel out. If some values are above average, others must be below by an equal total amount.
Ratio and Proportion — Numerical & Mental Ability · 8 cards
- Ratio
- is a comparison of two quantities of the same kind, written as a:b or a/b. Ratios have no units and can be simplified like fractions (12:18 = 2:3).
- Proportion
- states that two ratios are equal: a:b = c:d, written as a:b::c:d. In proportion, the product of extremes equals the product of means (a×d = b×c).
- Direct Proportion
- When one quantity increases, the other increases proportionally (more workers → more work). If a∝b, then a₁/a₂ = b₁/b₂.
- Inverse Proportion
- When one quantity increases, the other decreases proportionally (more speed → less time). If a∝1/b, then a₁/a₂ = b₂/b₁.
- Compound Ratio
- The ratio compounded from two or more ratios by multiplying corresponding terms. Compound ratio of a:b and c:d is ac:bd.
- Partnership
- applies ratio principles to profit/loss sharing based on capital invested and time period. Profit share ratio equals capital × time ratio.
- Fourth Proportional
- If a:b = c:d, then d is the fourth proportional. To find d: d = (b×c)/a.
- Third Proportional
- If a:b = b:c, then c is the third proportional to a and b. Formula: c = b²/a.
Profit and Loss — Numerical & Mental Ability · 7 cards
- Cost Price (CP)
- is the amount paid to acquire or produce an item. All profit/loss calculations reference this baseline.
- Selling Price (SP)
- is the amount received when selling the item. Profit occurs when SP > CP; loss occurs when SP < CP.
- Marked Price (MP)
- is the listed or tagged price before any discount. Discount is always calculated on MP, not CP.
- Profit
- is calculated as SP − CP, while Loss is CP − SP. Profit% and Loss% are always calculated on CP unless stated otherwise.
- Discount
- reduces the MP to arrive at the final SP. A single discount differs from successive discounts — two 10% discounts do NOT equal 20%.
- Break-even
- occurs when SP = CP, meaning neither profit nor loss. This concept appears in problems involving partial sales.
- False weight/measure
- creates an implicit profit by giving less quantity while charging for more.
Discount — Numerical & Mental Ability · 7 cards
- Marked Price (MP)
- is the labeled or list price before any discount. Selling Price (SP) is what the customer actually pays after discount is applied. The relationship is: SP = MP − Discount.
- Discount Percentage
- is always calculated on the marked price unless otherwise specified. If a 25% discount is offered on MP of ₹800, discount amount = 25% of 800 = ₹200, so SP = ₹600.
- True Discount (TD)
- is the simple interest on the present value (PV) of a sum due at a future date. Formula: TD = (PW × R × T)/100, where PW is present worth. Also, TD = Amount − PW, and PW = (Amount × 100)/(100 + R × T).
- Banker's Discount (BD)
- is the simple interest on the face value (amount) of a bill for the unexpired time. Formula: BD = (Amount × R × T)/100. Banker's discount is always greater than true discount because it's calculated on the larger face value rather than present worth.
- Relationship between BD and TD
- BD − TD = SI on TD. This means BD = TD + (TD × R × T)/100. Also, Amount = (BD × TD)/(BD − TD).
- Successive Discounts
- are multiple discounts applied one after another, not added together. If discounts are d₁% and d₂%, the single equivalent discount = d₁ + d₂ − (d₁ × d₂)/100. For three discounts d₁%, d₂%, d₃%, apply the formula twice sequentially.
- Conversion tip
- When time is given in months, convert to years by dividing by 12. For example, 9 months = 9/12 = 3/4 year. Always maintain consistency in time units.
Simple and Compound Interest — Numerical & Mental Ability · 8 cards
- Simple Interest (SI)
- Interest calculated only on the original principal throughout the loan/investment period. The interest amount stays the same every year.
- Compound Interest (CI)
- Interest calculated on principal plus accumulated interest from previous periods. The interest amount increases each period.
- Principal (P)
- The initial amount borrowed or invested.
- Rate (R)
- Annual interest rate expressed as a percentage per annum.
- Time (T)
- Duration of the loan or investment, typically in years. For half-yearly compounding, adjust both rate and time.
- Amount (A)
- Total money at the end, which equals Principal + Interest. For SI: A = P + SI. For CI: A is calculated directly using the CI formula.
- Compounding frequency
- Annually means interest is added once per year. Half-yearly means twice per year (divide rate by 2, multiply time by 2). Quarterly means four times per year (divide rate by 4, multiply time by 4).
- Difference between CI and SI
- For the same principal, rate and time, CI is always greater than SI (except for 1 year with annual compounding, when they're equal). The difference grows with time.
Time and Work — Numerical & Mental Ability · 8 cards
- Work is constant
- Total work is typically assumed as 1 unit or taken as LCM of all given days for easier calculation. This allows you to focus on rates rather than absolute quantities.
- Rate (Efficiency) = 1/Time
- If A completes work in 10 days, A's one-day work = 1/10. If B does it in 15 days, B's rate = 1/15. Combined rate when working together = 1/10 + 1/15.
- Time taken together = Total Work / Combined Rate
- When multiple workers collaborate, add their individual rates to get the combined efficiency, then divide total work by this sum.
- Negative work for emptying
- In pipes and cisterns problems, outlet pipes (emptying) have negative rates. If inlet fills in 6 hours and outlet empties in 8 hours, net rate = 1/6 - 1/8.
- Work done = Efficiency × Time
- If A works for 5 days at rate 1/10 per day, work done = 5 × (1/10) = 1/2. Remaining work = 1 - 1/2 = 1/2.
- Wages ∝ Work done
- Payment is distributed in the ratio of work done. If A works 10 days at efficiency 2 units/day and B works 15 days at 3 units/day, ratio = (10×2):(15×3) = 20:45 = 4:9.
- Man-days concept
- 10 men in 6 days = 60 man-days of work. Same work by 15 men = 60/15 = 4 days. Total work capacity (M₁D₁) = (M₂D₂) when work is equal.
- Efficiency and time are inversely proportional
- If A is twice as efficient as B, A takes half the time B takes. More efficient workers complete work faster.
Time and Distance — Numerical & Mental Ability · 7 cards
- Basic relationship
- Distance = Speed × Time. Any two known quantities give you the third. Speed is measured in km/hr or m/s; always convert units when mixing them.
- Speed conversion
- To convert km/hr to m/s, multiply by 5/18. To convert m/s to km/hr, multiply by 18/5. This conversion appears in almost every train problem.
- Average speed
- When a person travels different distances at different speeds, average speed = Total Distance ÷ Total Time. Never calculate average speed as the arithmetic mean of two speeds unless times are equal.
- Relative speed
- When two objects move in the same direction, relative speed = difference of speeds. When moving in opposite directions, relative speed = sum of speeds. This applies to trains passing each other and boats in streams.
- Trains
- A train must cover its own length plus any platform/bridge/pole length. Time to cross = (Train length + Object length) ÷ Speed. When two trains cross each other, consider sum of their lengths.
- Boats and streams
- Speed in still water (boat's own speed) combines with stream speed. Downstream speed = boat speed + stream speed. Upstream speed = boat speed − stream speed. Problems may give you upstream and downstream speeds to find boat and stream speeds.
- Meeting and overtaking
- Two objects starting from different points toward each other meet when sum of distances covered equals the total distance between them. When moving in the same direction, the faster overtakes when the difference in distances equals the initial gap.
Mensuration — Numerical & Mental Ability · 7 cards
- 2-D vs 3-D figures
- Two-dimensional shapes (plane figures) have area and perimeter; three-dimensional solids have surface area and volume. Don't confuse them in exam pressure.
- Perimeter is boundary length
- The distance around a closed figure. Used in fencing, framing and border problems. Measured in linear units (m, cm, km).
- Area is surface coverage
- The space enclosed within a 2-D boundary. Used in flooring, painting flat surfaces and land measurement. Measured in square units (m², cm², hectare).
- Surface area for solids
- Total area of all outer surfaces of a 3-D object. Lateral (curved) surface area excludes top/bottom. Total surface area includes all faces. Used in painting, wrapping and material estimation.
- Volume is space occupied
- The three-dimensional capacity of a solid. Used in filling, emptying, capacity and displacement problems. Measured in cubic units (m³, cm³, litre where 1 litre = 1000 cm³).
- Unit consistency is critical
- Always convert all measurements to the same unit before applying formulas. Mixing metres and centimetres causes wrong answers.
- Cost problems multiply quantity by rate
- If area = 50 m² and cost = ₹20/m², total cost = 50 × 20 = ₹1000. Watch for unit rates carefully.
Algebra — Numerical & Mental Ability · 8 cards
- Linear equations
- involve variables to the first power (x, not x²) and can have one or two variables; solving means finding the value that makes the equation true.
- Substitution method
- for two-variable linear equations: solve one equation for a variable, substitute into the other, then back-substitute to find both values.
- Elimination method
- adds or subtracts equations after multiplying by suitable constants to eliminate one variable, solving for the other.
- Quadratic equations
- have the form ax² + bx + c = 0 where a ≠ 0; they produce two solutions (roots) which may be real, equal, or involve negative discriminants.
- Factorization method
- works when the quadratic can be expressed as a product of two binomials: (x + p)(x + q) = 0, giving roots x = -p and x = -q.
- Quadratic formula
- x = [-b ± √(b² - 4ac)] / 2a solves any quadratic equation; memorize this formula and the discriminant (b² - 4ac) which determines the nature of roots.
- Algebraic identities
- are proven formulas for expanding or factorizing expressions — they save time in simplification problems.
- Transposing
- means moving terms across the equals sign (changing their sign) to isolate the variable — the foundation of equation solving.
Data Interpretation — Numerical & Mental Ability · 6 cards
- Data representation formats
- Tables show data in rows and columns; bar charts use vertical or horizontal bars; line graphs connect data points over time or categories; pie charts show percentage distribution of a whole.
- Reading scales carefully
- Always check axis labels, units (lakhs, crores, percentages) and legends before calculating. Misreading a scale by one unit can change your answer entirely.
- Percentage vs absolute values
- Pie charts show percentages; bar/line charts may show absolute numbers. Questions may ask you to convert between the two.
- Comparison questions
- "Which year had the highest…?", "What is the difference between…?", "Which category is greater?" — these test your ability to scan and compare data quickly.
- Approximation skill
- Exact calculations waste time. Learn to round numbers intelligently—if options are far apart, approximate; if close, calculate precisely.
- Multiple data sets
- Some questions combine data from two charts or a table and a graph. Read both carefully and ensure you're using the right data source for each part of the question.
Symbol & Relationship Test — Numerical & Mental Ability · 7 cards
- Symbol substitution
- Common operators (+, −, ×, ÷) are replaced by symbols (@, #, *, $, etc.) or interchanged with each other. You must decode which symbol represents which operation.
- BODMAS preservation
- Even when symbols change, the order of operations (Brackets, Orders, Division/Multiplication, Addition/Subtraction) remains unchanged. Always apply BODMAS after substitution.
- Statement-based operations
- Questions provide a key (e.g., "If + means ×, − means +, × means ÷, ÷ means −") followed by an expression to evaluate using the new meanings.
- Relationship validation
- Some questions ask you to determine if a given mathematical relationship becomes true after symbol substitution. You test each option systematically.
- Equation balancing
- Questions may present an equation with symbolic operators and ask which number or operation makes it valid.
- Combination puzzles
- Advanced variants combine symbol substitution with series, inequalities, or logical conditions requiring multi-step reasoning.
- Time management
- These questions reward methodical work. Write down the substitution key, replace symbols carefully, then calculate. Avoid mental shortcuts that skip steps.
Word Formation — Numerical & Mental Ability · 6 cards
- Letter Availability Rule
- You can only use letters that are present in the given word, and typically only as many times as they appear. If the source word is "TRIANGLE" (one T, one R, one A, one N, one G, one L, one E, one I), you cannot form "TREE" because you need two E's but only have one.
- Meaningful Words Only
- The words you form must be valid English dictionary words. Random letter combinations like "TRNGL" don't count, even if they use available letters. Common nouns, verbs, adjectives count; proper nouns (names of people, places) typically don't unless the question specifies otherwise.
- Case Insensitivity
- Letter case doesn't matter—treat uppercase and lowercase as identical. "A" and "a" are the same letter for formation purposes.
- Question Variations
- Common formats include (a) "Which word CAN be formed?" (b) "Which word CANNOT be formed?" (c) "How many 4-letter words can be formed?" (d) "What is the longest word possible?" Each requires a slightly different approach.
- Letter Frequency Check
- Before evaluating any option, mentally or physically tally the frequency of each letter in the source word. This frequency table is your constraint set—no word can exceed these limits.
- Common Word Patterns
- Familiarize yourself with high-frequency short words (AT, IT, IN, ON, AN, ARE, ART, TEN, NET, etc.) and common suffixes/prefixes (ING, TION, ER, ED, UN, RE). These patterns help you spot formable words faster.
Number Series — Numerical & Mental Ability · 8 cards
- Arithmetic Series
- Each term is obtained by adding (or subtracting) a constant difference to the previous term. Example: 3, 7, 11, 15 (difference = +4).
- Geometric Series
- Each term is obtained by multiplying (or dividing) the previous term by a constant ratio. Example: 2, 6, 18, 54 (ratio = ×3).
- Square and Cube Series
- Terms follow perfect squares (1, 4, 9, 16, 25) or perfect cubes (1, 8, 27, 64, 125), sometimes with slight addition/subtraction.
- Prime Number Series
- Sequence consists of prime numbers in ascending order: 2, 3, 5, 7, 11, 13, 17, 19, 23...
- Alternate Series
- Two independent patterns run alternately. Odd-positioned and even-positioned terms follow separate rules.
- Difference-of-Difference Pattern
- The difference between consecutive terms itself forms a pattern. Often the second-level differences are constant or follow a sequence.
- Mixed Operation Series
- Combination of addition/subtraction and multiplication/division applied alternately or in cycles.
- Wrong Number Detection
- One term breaks the pattern; identify it by checking consistency of differences or ratios across all terms.
Analogy Test — Numerical & Mental Ability · 6 cards
- Direct relationship identification
- The first pair establishes a rule (e.g., "multiply by 3" or "rotate 90° clockwise"). Your job is to decode this rule and apply it to the second pair.
- Numerical analogies
- Common patterns include arithmetic operations (addition, subtraction, multiplication, division), exponential relationships (squares, cubes, square roots), digit manipulation (sum of digits, product of digits, reverse), and positional patterns (prime numbers, even-odd sequences).
- Figural analogies
- Look for transformations like rotation (clockwise/anticlockwise), reflection (horizontal/vertical mirror), size changes (enlargement/reduction), shading changes (filled to unfilled), addition/removal of elements, or positional shifts of internal components.
- Odd one out
- Instead of completing a pair, you identify which of 4–5 given options doesn't follow the same relationship pattern as the others. Test each option against a hypothesis about the common rule.
- Multiple operations
- Some analogies involve two-step relationships (e.g., "add 5, then multiply by 2" or "rotate 45°, then add one element"). Always check if a single operation doesn't explain the relationship.
- Elimination strategy
- In figural analogies, eliminate options that violate the most obvious transformation first (wrong rotation direction, wrong number of elements), then check finer details (shading, internal positioning).
Analogy — Mental Aptitude / IQ / Reasoning · 8 cards
- Relationship identification
- The first step is always defining how the first two terms relate—ignore options until you understand the base relationship clearly.
- Parallel logic
- The relationship between the third and fourth terms must mirror the relationship between the first and second terms exactly, not just loosely.
- Word analogies
- Based on semantic relationships like synonyms, antonyms, category/member, worker/tool, place/product, gender pairs, young/adult forms, and intensity variations.
- Number analogies
- Follow mathematical patterns—arithmetic operations (+, −, ×, ÷), squares/cubes, prime numbers, digit sums, multiples, or positional relationships.
- Figural analogies
- Involve visual transformations—rotation, reflection, shading changes, element addition/deletion, size variation, or shape progression.
- Cross-category analogies
- Some questions mix categories (like profession to workplace or animal to habitat) requiring general knowledge alongside logical reasoning.
- Odd one out variation
- Sometimes you're asked to find which pair doesn't follow the pattern established by others—reverse application of analogy logic.
- Direction matters
- In relationships like "big to small" versus "small to big," or "cause to effect" versus "effect to cause," maintaining directional consistency is crucial.
Classification — Mental Aptitude / IQ / Reasoning · 7 cards
- Core principle
- Three or four items share a common property (category, relationship, or pattern); one item lacks this property and is the "odd one out."
- Verbal classification
- groups words by meaning, category, or function — examples include animals, professions, body parts, or cities. The odd word belongs to a different category or has a different characteristic.
- Alphabetical classification
- involves letter patterns — position in alphabet, vowel/consonant status, symmetry, or letter gaps. Look for positional values (A=1, B=2…Z=26) and alphabetical sequences.
- Numerical classification
- tests properties like even/odd, prime/composite, perfect squares/cubes, divisibility rules, or arithmetic patterns. One number violates the pattern shared by others.
- Figural classification
- presents images or shapes where three share visual properties — number of sides, rotation, shading, internal lines, or symmetry — while one differs.
- Multiple valid patterns
- Sometimes items share more than one property. Always verify your answer by confirming the majority pattern and ensuring the odd one truly breaks it.
- Elimination strategy
- When stuck, check each option against every other option to build the majority characteristic, then identify the outlier.
Coding-Decoding — Mental Aptitude / IQ / Reasoning · 8 cards
- Pattern Identification
- Every coding question follows a fixed rule applied uniformly to all letters/numbers. Your first task is to spot the rule by comparing the original word with its coded form.
- Letter-Shift Coding
- A common pattern where each letter shifts forward or backward by a fixed number (e.g., A→D means +3 shift). Reverse shifts work backwards through the alphabet.
- Position Value Coding
- Letters are assigned numerical values based on their position in the alphabet (A=1, B=2...Z=26). Operations like addition, subtraction or multiplication are performed on these values.
- Reverse Coding
- The word is simply written in reverse order (CAT → TAC). Often combined with other operations like letter shifts.
- Mixed Operations
- Complex questions apply multiple rules sequentially—e.g., reverse the word first, then apply +2 shift to each letter, then swap vowels and consonants.
- Symbol Substitution
- Specific letters or groups are replaced with predefined symbols or alternate letters. These require careful mapping and often involve a substitution table.
- Conditional Coding
- Different rules apply based on letter type (vowel vs consonant), letter position (first/last), or other conditions specified in the question.
- Decoding vs Encoding
- Decoding means finding the original word from the code; encoding means applying the rule to generate a new code. Both require understanding the same underlying pattern but in opposite directions.
Blood Relations — Mental Aptitude / IQ / Reasoning · 8 cards
- Direct relationships
- Parent, child, sibling, spouse — form the foundation. Mother/father, son/daughter, brother/sister, husband/wife must be crystal clear including gender implications.
- Second-generation relationships
- Grandparents, grandchildren, aunts, uncles, nieces, nephews. Remember: your father's/mother's siblings become your uncle/aunt; your siblings' children become your niece/nephew.
- In-law relationships
- Marriage creates new connections. Your spouse's parents are your in-laws; your children's spouses are your son-in-law/daughter-in-law; your spouse's siblings are your brother-in-law/sister-in-law.
- Only child/only son logic
- "Only son" means no brothers but sisters may exist. "Only child" means no siblings at all. This distinction is a common trap in blood relation questions.
- Gender determination
- Words like brother, son, father, uncle automatically tell gender. Words like child, sibling, parent require you to infer gender from context or the question itself.
- Reverse relationship principle
- If A is B's father, then B is A's son or daughter. Always verify by checking the relationship in both directions to catch logical errors.
- Generational counting
- Count generations to avoid confusion. Parent → child is one generation down. Grandparent → parent → child is two generations. Cousin relationships stay within the same generation.
- Self-reference statements
- "My father's only son" almost always means "I" (unless you have brothers). Decode these by replacing "my" with the speaker's name and drawing the tree.
Ranking & Order — Mental Aptitude / IQ / Reasoning · 7 cards
- Position from Top and Bottom
- If a person ranks Rth from top and Sth from bottom in a queue, total persons = R + S - 1. The "-1" accounts for counting the person twice.
- Position Interchange
- When two people swap positions, their new ranks can be determined by careful tracking. If A (5th from top) and B (12th from top) exchange, A becomes 12th and B becomes 5th.
- Overlapping Information
- When someone's position from both ends is given, you can calculate total members. When finding someone's new position after others leave/join, adjust the count accordingly.
- Age Ordering
- Questions may ask you to determine relative ages based on comparative statements (A is older than B, C is younger than D). Draw a simple linear diagram with youngest on left, oldest on right.
- Seating Sequences
- Linear arrangements (row seating) differ from circular ones. In linear: left-right matters and has endpoints. In circular: only relative positions matter, no fixed start/end.
- Bidirectional Ranking
- Some queues face different directions. "5th from left" when facing north differs from "5th from left" when facing south—directions reverse.
- Elimination Method
- When multiple conditions are given, systematically eliminate impossible arrangements until only one valid sequence remains.
Alphabet Test — Mental Aptitude / IQ / Reasoning · 8 cards
- Forward Position
- A=1, B=2, C=3 … Z=26. This is the natural counting order from the start of the alphabet.
- Backward Position
- Z=1, Y=2, X=3 … A=26. When counting from the right end, the positions reverse completely.
- Complementary Pairing
- The sum of forward and backward positions of any letter equals 27. If A is 1st from left, it's 26th from right (1+26=27). This shortcut eliminates the need to count both ways separately.
- Position After Rearrangement
- When the alphabet is reversed, the letter at position n from left moves to position n from right. Example: E (5th from left) becomes 5th from right in reversed alphabet (and V becomes 5th from left).
- Dictionary Order (Lexicographic Order)
- Words are arranged as they appear in a dictionary—letter by letter comparison from left to right. First letter is compared first; if same, move to second letter, and so on.
- Letter Shifting
- Questions may ask you to find letters that are a certain number of positions away. Count carefully in the specified direction—left means earlier in alphabet, right means later.
- Symmetry Trick
- Middle letters are M and N (13th and 14th positions). They are equidistant from both ends. Use them as mental anchors when calculating positions.
- Skip Patterns
- Some questions involve every alternate letter, every third letter, or skipping vowels. Identify the pattern before attempting the calculation.
Venn Diagrams — Mental Aptitude / IQ / Reasoning · 7 cards
- Set representation
- Each circle or closed figure represents a complete set or category of items/people with a common characteristic.
- Overlapping regions
- When two circles overlap, the intersection represents items that belong to both categories simultaneously (e.g., "female doctors" in the overlap of "women" and "doctors").
- Subset relationships
- When one circle is completely inside another, it indicates that all members of the smaller set are also members of the larger set (e.g., "roses" inside "flowers").
- Disjoint sets
- Circles that don't touch represent mutually exclusive categories with no common members (e.g., "living things" and "non-living things").
- Three-set diagrams
- Three categories create potential for various overlapping patterns — complete overlap, partial overlap, or no overlap.
- Universal set
- The rectangle containing all circles represents the universal set — everything under consideration in that context.
- Logical thinking over visual memory
- Don't memorize diagrams; instead, analyze each relationship by asking "Can something belong to both categories?" and "Must it belong to both?"
Syllogism — Mental Aptitude / IQ / Reasoning · 8 cards
- Categorical Propositions
- Statements are structured as "All A are B", "No A are B", "Some A are B", or "Some A are not B". These four forms are the building blocks of all syllogism problems.
- Absolute Truth
- Within syllogism, given statements are considered absolutely true regardless of real-world validity. The conclusion must follow from the logical structure alone, not from factual correctness.
- Venn Diagram Method
- Drawing overlapping circles for each category helps visualize all possible relationships. This visual approach prevents logical errors and makes complex statements manageable.
- Distribution of Terms
- In "All A are B", term A is distributed (completely contained) but B is not. In "No A are B", both terms are distributed. Understanding distribution helps apply formal logic rules correctly.
- Complementary Pairs
- "All" and "Some not" form one complementary pair; "No" and "Some" form another. If "All A are B" is false, then "Some A are not B" must be true, and vice versa.
- Possibility vs Definite
- Some questions ask "which conclusion definitely follows" while others ask "which can possibly be true". For possibility questions, if even one valid Venn diagram supports the conclusion, it's correct.
- No Assumption Rule
- Never introduce new information or relationships not present in the statements. The conclusion must be derivable purely from what's explicitly stated or necessarily implied.
- Either-Or Cases
- When two conclusions are complementary pairs and neither follows definitely, but one must be true, the answer is "either conclusion I or II follows".
Statement & Conclusion — Mental Aptitude / IQ / Reasoning · 7 cards
- Statement
- A declarative sentence presenting information, facts, opinions or situations that you must accept as absolutely true for the question's purpose, regardless of real-world accuracy.
- Conclusion
- A judgment or inference drawn from the statement; it "follows" only if it's a logical and direct consequence without requiring additional assumptions or external knowledge.
- Definite vs Probable
- A conclusion that "definitely follows" is one that must be true if the statement is true; a "probable" conclusion might be true but isn't guaranteed by the statement alone.
- Assumption Trap
- The most common error is accepting conclusions that require hidden assumptions — if you need to add information not in the statement to make the conclusion work, it doesn't follow.
- Scope Limitation
- Conclusions must stay within the scope of the statement — they cannot introduce new subjects, expand the context, or make generalizations beyond what's stated.
- Degree Matters
- Pay attention to absolute words (all, none, never, always) versus qualified words (some, many, generally, usually) — conclusions must match the degree of certainty in the statement.
- Multiple Conclusions
- When multiple conclusions are given, evaluate each independently — one may follow while others don't; the question will specify whether to select all that follow or the best one.
Mirror & Water Image — Mental Aptitude / IQ / Reasoning · 8 cards
- Mirror Image
- Reflection along a vertical axis placed to the left or right of the object. Left becomes right, right becomes left; top and bottom remain unchanged. Imagine holding text up to a mirror — that's your mirror image.
- Water Image
- Reflection along a horizontal axis placed below the object. Top becomes bottom, bottom becomes top; left and right positions remain unchanged. Visualize text reflected in still water.
- Vertical Symmetry
- Letters like A, H, I, M, O, T, U, V, W, X, Y have vertical symmetry — their mirror images look identical to the original. Always check for symmetry first to eliminate options quickly.
- Horizontal Symmetry
- Letters like B, C, D, E, H, I, K, O, X have horizontal symmetry — their water images may look similar or identical. Fewer letters are horizontally symmetrical than vertically symmetrical.
- Asymmetric Characters
- Letters like F, G, J, L, N, P, Q, R, S, Z change appearance significantly in both mirror and water images. These are high-yield for elimination in multiple-choice questions.
- Compound Objects
- When a figure contains multiple elements (clock face, geometric shapes with text), apply reflection rules to each component independently, then combine. The spatial relationship between elements also reverses.
- Axis Placement
- Mirror axis is typically vertical (left/right of object); water axis is horizontal (below object). Some questions specify axis position — always confirm before answering.
- Direction Reversal
- In mirror images, arrows pointing left point right and vice versa. In water images, upward arrows point down. Clock hands' positions also reverse in mirror (3 o'clock becomes 9 o'clock).
Paper Folding & Cutting — Mental Aptitude / IQ / Reasoning · 8 cards
- Fold multiplication principle
- Each fold doubles the number of layers. One fold creates 2 layers, two folds create 4 layers, three folds create 8 layers. A single punch through all layers creates holes equal to the number of layers.
- Symmetry along fold line
- When paper is folded and punched, the resulting holes appear symmetrically on both sides of the fold line when unfolded. The fold line acts as a mirror axis.
- Sequential folding matters
- The order of folds determines the final pattern. Fold left-then-up produces a different result than fold up-then-left, even with identical punches.
- Rotation vs reflection
- When a paper is folded diagonally, holes reflect diagonally. When folded horizontally or vertically, holes reflect along that axis. Corner folds create rotational patterns.
- Punch position tracking
- Mark mentally where the punch is relative to edges and previous fold lines. This position replicates across all layers when unfolded.
- Common fold types
- Half-fold (one crease), quarter-fold (two perpendicular creases), accordion fold (multiple parallel creases), and diagonal fold (corner-to-corner).
- Shape preservation
- Circular punches remain circular, triangular cuts remain triangular. The shape doesn't change, only the quantity and position multiply.
- Edge effects
- Punches near edges after folding produce asymmetric patterns. Always check if the punch is centered or offset toward an edge.
Figure Completion — Mental Aptitude / IQ / Reasoning · 8 cards
- Pattern continuity
- Every figure series follows a consistent rule that applies throughout. The missing figure must maintain this continuity without breaking the established pattern.
- Rotation patterns
- Figures may rotate clockwise or anticlockwise by fixed angles (45°, 90°, 180°). The completing figure continues this rotational sequence.
- Addition/Subtraction of elements
- New elements may be added progressively, or existing elements removed systematically. Count carefully to identify the increment or decrement pattern.
- Shape transformation
- One shape may gradually transform into another through intermediate steps. The completing figure represents the next logical transformation stage.
- Shading/color progression
- Shading patterns (empty → half-shaded → fully shaded) or color changes follow predictable sequences that the answer must continue.
- Positional movement
- Elements within a figure may move in specific directions (up/down, left/right, diagonal) by fixed units. Track the movement pattern to predict the next position.
- Mirror/symmetry operations
- Figures may reflect across horizontal or vertical axes. The completing figure maintains the symmetry rule established in the series.
- Size variation
- Elements may increase or decrease in size systematically. The completing figure follows the size progression pattern.
Dice & Cube — Mental Aptitude / IQ / Reasoning · 6 cards
- Standard die numbering
- On a normal die, opposite faces always sum to 7. So 1 is opposite 6, 2 is opposite 5, and 3 is opposite 4. This is the fundamental property used in most dice problems.
- Rotation preserves adjacency
- When a die rolls, the top and bottom faces change, but the four faces forming the "belt" around the middle maintain their circular order. If you know two adjacent faces, you can deduce others through rotation.
- Two views are often sufficient
- Most exam questions show a die in two or three positions. By comparing these views and noting which faces appear together, you can deduce the complete configuration and identify opposite faces.
- Painted cube problems
- A large cube is painted and cut into smaller unit cubes. The number of cubes with 0, 1, 2, or 3 painted faces follows fixed formulas based on the cube's dimensions (n × n × n).
- Corner, edge, and face cubes
- In a painted cube of side n, corner cubes have 3 painted faces (always 8), edge cubes have 2 painted faces, face-center cubes have 1 painted face, and internal cubes have 0 painted faces.
- Net diagrams
- Sometimes a die is shown as an unfolded net. To find opposite faces in a net, count the number of faces between them in a straight row or column — opposites are always separated by exactly one face in a standard net.
Problem Solving — Mental Aptitude / IQ / Reasoning · 8 cards
- Linear Seating
- People sit in a row facing north or south. Positions are numbered left-to-right. Statements like "A sits third from left" or "B sits two places away from C" define relative positions. Always clarify which end is which.
- Circular Seating
- People sit around a circular table, either all facing center or all facing outward. Positions are relative — no absolute "first" position. Use one person as reference point and place others clockwise/anticlockwise relative to them.
- Rectangular/Square Seating
- People sit on four sides of a table. Identify corners and middles clearly. Note who faces whom across the table — this is crucial for solving these problems.
- Scheduling Problems
- Assignments of activities, classes, or shifts across different time slots or days. Constraints specify what cannot occur together or what must occur in sequence. Use a grid or timeline to track possibilities.
- Constraint-Based Deduction
- Most problems give you conditional statements ("If A sits here, then B cannot sit there"). Process these systematically — direct constraints first, then derived conclusions.
- Elimination Technique
- When multiple possibilities exist, use additional constraints to eliminate impossible arrangements. Often the answer emerges by ruling out 3-4 options rather than directly constructing the solution.
- Variable Tracking
- In complex puzzles with multiple attributes (person-position-object-color), create a matrix to track which combinations are possible and which are ruled out.
- Definite vs Possible
- Some questions ask what "must be true" (only one answer) versus what "could be true" (multiple valid scenarios exist). Read the question type carefully.
Decision Making — Mental Aptitude / IQ / Reasoning · 7 cards
- Eligibility Decision Problems
- Multiple candidates described with attributes (age, qualification, experience, etc.). You must apply a set of conditions/rules to determine who qualifies. Check each condition sequentially for each candidate.
- Course of Action Questions
- A problem situation is described, followed by possible responses (I, II, III, etc.). You decide which action(s) logically follow or should be taken. Actions must be practical, address the root issue, and not contradict facts.
- Rule Application
- Given a set of rules or procedures, determine how they apply to specific cases. Often involves exceptions ("except when...") that override standard conditions.
- Condition Checking Order
- Always verify conditions in the order given. Some conditions may have provisos or relaxations mentioned later — read the complete rule set before deciding.
- Implicit vs Explicit Information
- Base decisions strictly on stated information. Don't add assumptions from "general knowledge" unless the question asks you to use practical judgment.
- Negative Conditions
- Pay special attention to "not", "except", "unless", "only if" — these reverse or limit conditions. A single overlooked negative word changes the answer.
- Multiple Valid Actions
- When asked "which action should follow", sometimes both (A) and (B) are sensible, but one is more direct or appropriate. Prioritize immediate, practical solutions over vague or delayed responses.
Visual Memory & Discrimination — Mental Aptitude / IQ / Reasoning · 6 cards
- Visual Working Memory
- The brain's temporary storage system for visual information, lasting 10-30 seconds without rehearsal.
- Feature-Based Encoding
- The brain remembers visual stimuli by encoding distinctive features (shape, colour, position, size). Focus on unique characteristics during observation rather than trying to memorize everything.
- Change Blindness
- The phenomenon where observers fail to detect changes in visual scenes. Exam questions deliberately introduce subtle variations to test whether you encoded specific details.
- Visual Discrimination
- The ability to distinguish between similar visual stimuli by identifying subtle differences in orientation, shading, size or arrangement. Requires systematic comparison rather than quick glancing.
- Pattern Recognition
- The cognitive process of matching incoming visual information against stored mental templates. Faster recognition occurs when you categorize shapes (triangles, circles) rather than memorizing raw pixel data.
- Spatial Memory
- Remembering the position and arrangement of objects relative to each other. Questions may shuffle positions or orientate figures differently to test true spatial encoding.
Observation — Mental Aptitude / IQ / Reasoning · 8 cards
- Systematic scanning
- Always follow a consistent direction (left-to-right, top-to-bottom) when counting to avoid missing or double-counting elements.
- Overlapping figure recognition
- When shapes overlap, trace each complete figure independently; mark mentally or lightly with finger to track what you've counted.
- Hidden element detection
- Numbers or letters embedded in complex designs require focusing on small segments; squinting slightly or changing viewing angle can help reveal hidden patterns.
- Size and orientation variation
- The same shape rotated, flipped or scaled differently still counts as that shape; train your eye to recognize figures regardless of transformation.
- Distraction elimination
- Complex diagrams include intentional visual noise; learn to filter out irrelevant lines, colors or patterns that don't contribute to the answer.
- Negative space observation
- Sometimes the answer lies in what's NOT present — gaps, missing elements or the space between figures can be as important as the figures themselves.
- Time management
- Observation questions can be time sinks; set a 45-60 second limit per question and move on if stuck.
- Verification habit
- Always recount quickly if time permits; observation errors are often simple miscounts that a second glance catches.
