Q1 · CH-Ratio & Proportion
If the ratio of two numbers is 3:5 and their sum is 48, what is the larger number?
- (a) 18
- (b) 24
- (c) 30
- (d) 45
Show answer ↓
Answer: (c) 30
(c) is correct: Sum of ratio parts is 8, so each part is 48/8 = 6; the larger number is 5 x 6 = 30. (d) 45 is wrong because it does not match the sum of 48 with ratio 3:5.
Q2 · CH-Time Value of Money
The present value of Rs. 1,000 receivable after 2 years at 10% per annum compounded annually is approximately:
- (a) Rs. 826
- (b) Rs. 900
- (c) Rs. 909
- (d) Rs. 1,100
Show answer ↓
Answer: (a) Rs. 826
(a) is correct: PV = 1000 / (1.10)^2 = 1000 / 1.21 = Rs. 826.45. (c) Rs. 909 is the one-year discounted value, which is wrong for a 2-year period.
Q3 · CH-Permutation & Combination
The number of ways to arrange 4 different books on a shelf is:
- (a) 8
- (b) 16
- (c) 24
- (d) 12
Show answer ↓
Answer: (c) 24
(c) is correct: Arrangements of n distinct objects in a line are n!, so 4! = 24. (b) 16 is wrong because it is 2^4, which counts selections, not arrangements.
Q4 · CH-Ratio & Proportion
If a : b = 3 : 4 and b : c = 6 : 7, then a : b : c is:
- (a) 9 : 12 : 14
- (b) 3 : 4 : 7
- (c) 9 : 12 : 16
- (d) 18 : 24 : 21
Show answer ↓
Answer: (a) 9 : 12 : 14
(a) is correct: make b common (LCM 12), so a : b = 9 : 12 and b : c = 12 : 14, giving 9 : 12 : 14. (d) wrongly writes 28 as 21 for c.
Q5 · CH-Time Value of Money
The compound interest on ₹10,000 at 10% p.a. for 2 years, compounded annually, is:
- (a) ₹2,000
- (b) ₹2,050
- (c) ₹2,100
- (d) ₹2,200
Show answer ↓
Answer: (c) ₹2,100
(c) is correct: the amount is 10,000 × 1.1² = ₹12,100, so the interest is ₹2,100. (a) ₹2,000 is the simple interest, which ignores interest earned on interest.
