32 days
(c) 30 days​

Answer 1

Answer:

Given that fort had provision of food for 1200 men for 28 days.

Therefore, after 4 days, the remaining food is sufficient for 1200 men for 24 days

Remaining men after 4 days =1200−300=900

Assume that after 4 days,the remaining food is sufficient for 900 men for x days

Now, we find for how long food lasts for 900 men is as follows:

900

1200
