Answer 2

Step-by-step explanation:

ANSWER

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

Therefore, after 4 days, the remaining food 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 = 24x

⇒x= 900/1200 ×24

⇒x= 34×24

⇒x=4×8

⇒x=32

Hence, the food lasts for 32 days now.
