Problem: 4000 soldiers in a camp have enough food for 190 days. After 30 days, 800 soldiers are posted elsewhere. How long would the remaining food last?

View all: PUBALI BANK OFFICER (JO) | WRITTEN QUESTION (MATH) SOLVE | 2013

Correct Answer: ans: 200 days

Explanation:

After 30 days 4000 soldiers have the food of (190 – 30) = 160 days.

After posting of 800 soldiers, there are (4000 – 800) = 3200 soldiers.

4000 soldiers can eat = 160 days

1 soldiers can eat = 4000 x 160 days

3200 soldiers can eat =$\frac{400×160}{3200}$=200 day
