Q1. At a ship, food was initially sufficient for 50 men for 20 days. After 10 days, half of the men died due to a disease. How many more days will the remaining food last?
Answer: 20 days
Explanation: Total food = 50 × 20 = 1000 man-days; after 10 days, 500 man-days remain; with 25 men left, food lasts 500/25 = 20 more days.
