A fort had provision of food for 150 men for 85 days. After 15 days, 25 men left the fort. Find the number of days for which the remaining food will last.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 84.
Total food = 150 men × 85 days = 12,750 man‑days
Food consumed in first 15 days = 150 × 15 = 2,250 man‑days
Remaining food = 12,750 − 2,250 = 10,500 man‑days
Remaining men = 150 − 25 = 125
Days food will last = 10,500 ÷ 125 = 84 days
