In an army camp, there is food provision for 500 cadets for 25 days. If 125 more persons join the army camp on the first day itself, then for how many days will the provision last?

Correct option is A

Given:

There is a provision of food for 500 cadets for 25 days

125 more persons joined the army camp.

Solution:

Let the food be enough for x days.

=> 500 × 25 = 625 × x

=> 12500 = 625x

=> x = 20
