Q1 · Ratio and Proportion
If two numbers are in the ratio 5:7 and their sum is 84, find the smaller number.
- A. 30
- B. 35
- C. 40
- D. 45
Answer and solution
Answer: B
Let numbers be 5x and 7x. Then 12x=84, so x=7. Smaller number = 5×7 = 35.
Q2 · BODMAS / Simplification
Simplify: 48 + 12 ÷ 3 - 6 × 2
- A. 38
- B. 40
- C. 42
- D. 44
Answer and solution
Answer: B
Following BODMAS: 12÷3=4, 6×2=12, then 48+4-12=40.
Q3 · Mensuration
The area of a circle is 154 sq cm. What is its radius? (Use π = 22/7)
- A. 5 cm
- B. 6 cm
- C. 7 cm
- D. 8 cm
Answer and solution
Answer: C
Using πr² = 154, with π=22/7: r²=49, so r=7 cm.
Q4 · Trigonometry
If sin θ = 3/5, then what is the value of cos θ?
- A. 4/5
- B. 5/3
- C. 3/4
- D. 5/4
Answer and solution
Answer: A
Using sin² θ + cos² θ = 1, we have (3/5)² + cos² θ = 1. So cos² θ = 1 - 9/25 = 16/25, hence cos θ = 4/5.
Q5 · Height and Distance
From the top of a 60 m high tower, the angle of depression of a point on the ground is 30°. What is the distance of the point from the base of the tower?
- A. 60√3 m
- B. 30√3 m
- C. 60 m
- D. 120 m
Answer and solution
Answer: A
Using tan 30° = height/distance, we have 1/√3 = 60/d. Hence d = 60√3 m.
Q6 · Elementary Statistics
The average weight of 8 persons increases by 2.5 kg when a new person replaces one of them weighing 65 kg. What is the weight of the new person?
- A. 80 kg
- B. 85 kg
- C. 90 kg
- D. 75 kg
Answer and solution
Answer: B
Total increase in weight = 8 × 2.5 = 20 kg. Weight of new person = 65 + 20 = 85 kg.
Q7 · Square Root
What is the square root of 10404?
- A. 98
- B. 102
- C. 104
- D. 106
Answer and solution
Answer: B
By factorization or calculation, √10404 = 102, which can be verified as 102 × 102 = 10404.
Q8 · Analogies
Select the option that is related to the third number in the same way as the second number is related to the first number: 6 : 35 :: 8 : ?
- A. 63
- B. 65
- C. 72
- D. 80
Answer and solution
Answer: A
The pattern is n² - 1. For 6: 6² - 1 = 35. For 8: 8² - 1 = 64 - 1 = 63.
Q9 · Venn Diagram
Which Venn diagram best represents the relationship among Teachers, Doctors, and Women?
- A. Three separate circles
- B. Three overlapping circles
- C. One circle inside another
- D. Two circles inside a larger circle
Answer and solution
Answer: B
Teachers, Doctors, and Women can overlap (e.g., a woman can be a teacher or doctor), so three overlapping circles best represent this relationship.
Q10 · Relationships
Introducing a man, a woman said, 'He is the son of my mother's only daughter.' How is the man related to the woman?
- A. Brother
- B. Son
- C. Nephew
