Question

A hostel of 500 boys has provisions for 4 days. if the provisions were continued for 20 days, how many students have gone out of the hostel ​

Answer 1

Answer:

400 students have gone out of the hostel.

Step-by-step explanation:

We are given that a hostel of 500 boys has provisions for 4 days. If the provisions were continued for 20 days.

Let the number of students who remained in the hostel be 'x'.

As we know that the amount of provisions is fixed for both the cases, i.e;

Amount of provision = Number of boys x Number of days it lasts

So, according to the question;

500 × 4 = x × 20

2000 = x × 20

x = 200 upon 20

x = 100

This means that if the provisions were continued for 20 days, then that will be available for 100

boys only.

So, the number of students who have gone out of the hostel = 500-100= 400 boys.
