Question

A hostel of 500 boys has provision for 4 days. If the provision were continued for 20 days how many student have gone out of the hostel

Answer 1

Hi ,
In this question,
Note:
- Amount of provision = no. of boys * no. of days = constant
- The value of provisions remain same in both cases and hence can be equated

Let number of boys who remained = x

500*4 = x*20
2000 = 20x
x = 2000/20
x = 100
x = 100 boys

so number of boys who left are
= total boys - boys who remained
= 500 - x
= 500 - 100
= 400 boys

answer = 400 boys went out of the hostel.

Hope it helped.
Let me know if any doubts.
Cheers !!!
