25 men can consume 250kg of wheat in 20 days. 20 men cang consume how much wheat in 25 days?
Correct answer: C. 250
- A. 300
- B. 200
- C. 250
- D. 350Downloading Digital Educational Resources
Explanation
The consumption rate is 250 kg ÷ (25 men x 20 days) = 250 kg ÷ 500 man-days = 0.5 kg per man-day. Therefore, 20 men consume 20 x 25 x 0.5 kg = 250 kg in 25 days. The likely mistaken answer is 200 kg, which fails to adjust correctly for both the new number of men and the new duration.
