Twelve men take 6 hours to finish a piece of work. After the 12 men have worked for 1 hour, the boss calls in 8 more men. How many more hours would 20 men take to complete the remaining work?
A
3
B
5
C
2
D
4
Explanation and memory cue
Twelve men take 6 hours, so total work = 12 × 6 = 72 man-hours. After 1 hour, 12 men complete 12 man-hours, leaving 60 man-hours. Now 20 men work on the remaining 60 man-hours, so time needed = 60 ÷ 20 = 3 hours. However, the options do not include 3 hours as the correct answer for the remaining time after the first hour. Rechecking: After 1 hour, work done = 12 men × 1 hour = 12 man-hours. Remaining work = 72 - 12 = 60 man-hours. With 20 men working, time = 60 ÷ 20 = 3 hours. The correct answer is 3 hours, which corresponds to option A, not C. Therefore, correct_answer should be A.

Which number will complete the following number series? 3, 6, 15, ___, 123, 366
A
34
B
59
C
42
D
60
Explanation and memory cue
The number series follows the pattern where each term is obtained by multiplying the previous term by 3 and then subtracting 3. Specifically: 3 × 3 - 3 = 6, 6 × 3 - 3 = 15, 15 × 3 - 3 = 42, 42 × 3 - 3 = 123, and 123 × 3 - 3 = 366. Therefore, the missing number in the series is 42, which corresponds to option C.

Profit and Loss

MathematicsFIA
A retailer increases the selling price by 25%, due to which his profit percentage increases from 20% to 25%. What is the percentage increase in cost price?
A
20%
B
30%
C
25%
D
50%
Explanation and memory cue
Let the original cost price be 100. With 20% profit, the original selling price is 120. After a 25% increase, the new selling price is 120 × 1.25 = 150. The new profit is 25%, so the new cost price must satisfy: new cost price × 1.25 = 150, giving new cost price = 120. The increase in cost price is from 100 to 120, which is a 20% increase. However, this contradicts the options, so let's re-examine: The original profit is 20%, so SP1 = CP × 1.20. After a 25% increase in selling price, SP2 = SP1 × 1.25 = CP × 1.20 × 1.25 = CP × 1.5. The new profit is 25%, so SP2 = new CP × 1.25. Equate: new CP × 1.25 = CP × 1.5 → new CP = (CP × 1.5)/1.25 = CP × 1.2, which is a 20% increase in cost price. Therefore, the percentage increase in cost price is 20%. The correct answer is A, not B. Correction made accordingly.
