SZF IOS 2022 PYQ-pattern questions

Showing 10 of the 20 PYQ-pattern questions in this set — freshly worded in that year's pattern, not the original questions. Answers and solutions open under each question.

Q1 · Work, Energy and Power
A machine does 2400 J of work in 30 seconds. What is the power of the machine?
- A. 60 W
- B. 80 W
- C. 100 W
- D. 120 W
Answer and solution
Answer: B
Power = Work / Time = 2400 J / 30 s = 80 W.
Q2 · Motion
A car accelerates uniformly from rest and covers 100 m in 10 seconds. What is the acceleration of the car?
- A. 1 m/s²
- B. 2 m/s²
- C. 5 m/s²
- D. 10 m/s²
Answer and solution
Answer: B
Using s = ut + (1/2)at² with u = 0, we get 100 = 0 + (1/2)a(10)². Solving, a = 200/100 = 2 m/s².
Q3 · Is Matter Around Us Pure?
A student wants to separate a mixture of common salt and ammonium chloride. Which method would be most suitable?
- A. Filtration followed by evaporation
- B. Sublimation followed by dissolution and evaporation
- C. Distillation
- D. Chromatography
Answer and solution
Answer: B
Ammonium chloride sublimes on heating, leaving behind common salt. The sublimed ammonium chloride can be collected separately, while salt remains in the container.
Q4 · Magnetic Effects of Current
Fleming's left-hand rule is used to determine the direction of which of the following?
- A. Induced current in a conductor
- B. Force on a current-carrying conductor in a magnetic field
- C. Magnetic field around a current-carrying conductor
- D. Direction of magnetic field lines
Answer and solution
Answer: B
Fleming's left-hand rule is used to find the direction of force (motion) experienced by a current-carrying conductor placed in a magnetic field, with the thumb indicating force, forefinger showing field, and middle finger showing current direction.
Q5 · Tissues
In which type of plant tissue would you find cells with thick, lignified walls that provide mechanical support?
- A. Parenchyma
- B. Collenchyma
- C. Sclerenchyma
- D. Chlorenchyma
Answer and solution
Answer: C
Sclerenchyma tissue has thick, lignified cell walls that make cells rigid and provide mechanical strength and support to plant parts.
Q6 · Metals and Non-Metals
When aluminium metal reacts with dilute hydrochloric acid, which gas is evolved and what is its confirmatory test?
- A. Oxygen gas; glowing splint relights
- B. Hydrogen gas; burns with a pop sound
- C. Carbon dioxide; turns lime water milky
- D. Chlorine gas; bleaches litmus paper
Answer and solution
Answer: B
Aluminium reacts with dilute HCl to produce hydrogen gas and aluminium chloride; hydrogen gas burns with a characteristic pop sound when ignited.
Q7 · How Do Organisms Reproduce
In humans, fertilization normally occurs in which part of the female reproductive system?
- A. Uterus
- B. Fallopian tube
- C. Ovary
- D. Cervix
Answer and solution
Answer: B
Fertilization typically occurs in the fallopian tube (oviduct) where the sperm meets the ovum after ovulation.
Q8 · Life Processes
In the human kidney, which of the following substances is NOT normally found in the glomerular filtrate?
- A. Glucose
- B. Urea
- C. Plasma proteins
- D. Amino acids
Answer and solution
Answer: C
Plasma proteins are too large to pass through the glomerular filtration membrane, so they remain in the blood and are not normally found in the filtrate.
Q9 · Scientific Reasoning
A scientist notices that bread left in a sealed container develops mold faster at 30°C than at 10°C. What scientific reasoning explains this observation?
- A. Mold grows slower in sealed containers
- B. Higher temperatures increase the metabolic rate of mold fungi
- C. Cold temperatures destroy mold spores completely
- D. Bread contains more nutrients at higher temperatures
Answer and solution
Answer: B
Higher temperatures enhance enzyme activity and metabolic processes in fungi, allowing mold to grow and reproduce more rapidly at 30°C compared to cooler temperatures.
Q10 · Higher Order Thinking
Three identical plants are kept in separate sealed transparent containers. Container X has normal air, Container Y has air enriched with extra CO₂, and Container Z has air with reduced CO₂. After two weeks in sunlight, which outcome is most likely?
- A. Plant in Container Z shows maximum growth
- B. Plant in Container Y shows maximum growth
- C. All three plants show identical growth
- D. Plants in all containers die due to lack of oxygen
Answer and solution
Answer: B
Plants use CO₂ for photosynthesis. Increased CO₂ availability in Container Y enhances the rate of photosynthesis, leading to faster growth compared to normal or reduced CO₂ conditions.

SZF IOS 2022 previous year paper — frequently asked questions

Where can I solve the SZF IOS 2022 previous year paper (PYQ) free online?

At https://shishya.in/exams/SZF_IOS/pyq/2022 you can solve SZF IOS 20 PYQ-pattern questions modelled on the 2022 paper free. Shishya does not reproduce the original paper: every question is freshly worded in that year's pattern — same topics, style and difficulty, new wording and numbers, and this set holds 20 questions, not the whole paper. They run as a timed mock with instant scoring, step-by-step solutions and topic-wise weak-area analysis. No fee and no coaching enrolment needed.

Are these the actual SZF IOS 2022 paper questions?

No. They are PYQ-pattern questions modelled on the SZF IOS 2022 paper — freshly worded practice questions in the same pattern, not the original questions, which Shishya does not reproduce. This set holds 20 questions. For a whole paper in one sitting, Shishya has a free full-length mock in the real pattern (50 questions, 60 minutes): the "Full-Length Mock (Real Pattern)" tile at https://shishya.in/exams/SZF_IOS

Do these SZF IOS 2022 pattern questions come with solutions and analysis?

Are previous year papers enough to crack SZF IOS?

Previous-year papers are the best signal of what the exam actually tests, but they work best with targeted practice and a plan. On Shishya (all free): solve PYQ-pattern sets year-wise, drill weak topics via the Mistake Notebook, follow a day-by-day plan from the Personal Coach at https://shishya.in/coach and sit the Sunday All-India Live Test at https://shishya.in/live-test to see where you stand nationally.
