Question

There are 250 students in a camp. There is enough food for them for 15 days. How long will the food last, if 50 more students join the camp?​

Answer 1

Answer:

This is a case of inverse proportion.

Number of students in camp = 250

Number of days the food will last = 15 days

Number of students in camp afterwards = 300

Let number of days the food will last now be x.

So 250*15=300x

x = 250*15/300

= 12.5 days

So the food will last for 12.5 days if 50 more students join the camp.
