Question

A camp had provisions for 300 soldiers for 90 days. After 20 days, 50 soldiers left the camp. How
would the food last at the same rate?



​

Answer 1

Answer:

Remaining number of men =(300−50)=250.

Remaining number of days =(90−20)days=70 days

300 men had provisions for 70 days

1 man had provisions for (300×70) days ...[less men, more days]

250 men had provisions for

250

300×70

days =84 days ...[more men, less days]

Hence, the remaining food will last for 84 days.
