In a ship the provisions are sufficient for 800 men for 50 days. How long will these be sufficient for if there would have been 200 more men?
Correct answer: A. 40
- A. 40
- B. 50
- C. 30
- D. 56
Explanation
The provisions equal 800 men x 50 days = 40,000 man-days. For 800 + 200 = 1000 men, the duration is 40,000 man-days ÷ 1000 men = 40 days. The likely mistaken answer is 50 days, which ignores the 200 additional men.
