Question

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

___

days.

Answer 1

Remaining number of men

$=250-50=200$

Remaining number of days

$=(350-25)days=325$.

250 men had provisions for 325 days

1 man had provisions for $(250\times 325)$ days

200 men had provisions for $\frac{(250\times 325)}{200}$ days

$=406.25days$

$=406days$

Hence, the remaining food will last for 406 days.
