Sample Questions from this Test

Question 1:

If salary of A is 25% less than that of B, then B's salary is how much more than that of A?
A.25%
B.30%
C.33 1/3%
D.36%

Let B's salary = 100. Then A's salary = 75. Difference = 25. Percentage by which B is more than A = (25/75) × 100 = 33 1/3%.

Question 2:

An item is sold at a fixed value. If it had been sold at 2/3 of the fixed value, the loss would have been 10%. Accordingly, what would have been the gain on selling at the fixed price?
A.5%
B.25%
C.35%
D.45%

Let CP = 100x. At 2/3 of fixed value there's a 10% loss, so SP there = 90x. Fixed value = (3/2) × 90x = 135x. Gain% at fixed price = (135x − 100x)/100x × 100 = 35%.

Question 3:

If a person sells 2 horses at Sonpur fair for Rs. 14,000 each, on one he gains 15% but he sells the other for 15% loss. Accordingly how much profit/loss did he have in the entire trade?
A.No gain no loss
B.1% gain
C.1% loss
D.2.25% loss

When two articles are sold at the same price, one at R% profit and the other at R% loss, there is always a net loss of R²/100%. Net loss = 15²/100 = 2.25%.

Question 4:

The average temperature on Monday, Tuesday and Wednesday is 40°C. Tuesday, Wednesday and Thursday have an average temperature of 41°C. If Thursday's temperature was 42°C, what was the temperature on Monday?
A.30°C
B.33°C
C.36°C
D.39°C

Total(Mon+Tue+Wed) = 3×40 = 120. Total(Tue+Wed+Thu) = 3×41 = 123. Subtracting: Thu − Mon = 3. Since Thu = 42, Mon = 42 − 3 = 39°C.

Question 5:

If the value of sugar falls by 10%, then how much % of sugar consumption in a house should be increased so that expenditure on sugar does not fall?
A.10%
B.9%
C.9 1/11%
D.11 1/9%

Let original price = 10 units, reduced price = 9 units. Since expenditure = price × consumption must stay constant, consumption must rise from 9 to 10, i.e. by 1/9 = 11 1/9%.

Question 6:

If there are 32 girls in the class and the ratio of girls to boys is 16 : 9, then what percentage (%) of the girls are in the class?
A.32%
B.48%
C.64%
D.80%

16y = 32 ⟹ y = 2. Boys = 9×2 = 18. Total = 32+18 = 50. Percentage of girls = (32/50)×100 = 64%.

Question 7:

A tailor has 37.5 meters of cloth and has to cut 8 pieces in one meter. Accordingly how many pieces will be made in the whole cloth?
A.320
B.360
C.400
D.None of these

Pieces = 37.5 × 8 = 300, which is not among the first three options, so the answer is 'None of these'.

Question 8:

A monkey can climb a round pole, 21 meters high, 6 meters in one minute. But, it slips by 3 meters in next one minute. How much time will the monkey take in reaching at the top of the pole?
A.10 minutes
B.11 minutes
C.12 minutes
D.13 minutes

Net gain per 2 minutes = 3 m. After 9 minutes it has net-climbed 13.5 m in a repeating up-down pattern; tracking minute-by-minute peaks (6,3,9,6,12,9,15,12,18) shows that in the 11th minute it climbs 6 m from 15 to 21 m, reaching the top before it can slip again. So total time = 11 minutes.

Question 9:

If Rs 680 is divided between A, B and C in such a way that A gets 2/3 of B and B gets 1/4 of C. Then, how much amount did they get respectively?
A.A - Rs. 75, B - Rs. 325, C - Rs. 280
B.A - Rs. 80, B - Rs. 120, C - Rs. 480
C.A - Rs. 90, B - Rs. 200, C - Rs. 400
D.A - Rs. 100, B - Rs. 200, C - Rs. 380

A:B = 2:3, B:C = 1:4 = 3:12. So A:B:C = 2:3:12, sum = 17 parts = 680 ⟹ 1 part = 40. A = 80, B = 120, C = 480.

Question 10:

If 20% of another number is added to a number, then that number increases by 50%. Then what is the ratio of those two numbers?
A.3 : 2
B.2 : 3
C.5 : 2
D.Can't be determined

Let numbers be b (which increases) and a. b + 0.2a = 1.5b ⟹ 0.2a = 0.5b ⟹ a/b = 5/2. So ratio = 5:2.
