A fort had a provision of food for 150 men for 45 days. After 10 days, 25 men left the fort. For how many days will the remaining food last?
A
146/5
B
149/4
C
42
D
54
Correct Option:
C
Explanation
Total food initially = 150×45=6750 man-days. During the first 10 days, 150×10=1500 man-days are consumed, leaving 5250. After 25 men leave, 125 remain. Remaining duration =5250÷125=42 days.
