SSC GD Constable 4 Feb 2025 Shift 2 Paper

Remaining food = Initial food provision - Food consumed in 15 days
Remaining days of food $=$ Remaining food $∕$ Remaining men
Calculation:
Initial food provision $=150$ men $\times 85$ days $=12750$ man-days
25 men left after 15 days
Food consumed in 15 days $=150$ men $\times 15$ days $=2250$ man-days
Remaining men $=150-25=125$ men
Remaining food = 12750 man-days - 2250 man-days = 10500 man-days
Remaining days of food = 10500 man-days / 125 men
⇒ Remaining days of food $=84$ days
