Question

An army camp of 250 men has provision for 350 days. After 25 days, 50 men died due to an epidemic. The remaining food will last for

___ days (rounded to nearest integer).

Answer 1

Remaining number of men = 250 - 50 = 200 men
Remaining number of days = (350 - 25) days = 325 days.

250 men had provisions for 325 days
1 man had provisions for (250 × 325) days
200 men will have provisions for $\frac{(250\times 325)}{200}$ additional days
= 406.25days = 406 days
hence, the remaining food will last for 406 more days.
