Answer 1

Given :

A hostel of 500 boys has provisions for 4 days.

To Find :

If the provisions were continued for 20 days, how many students have gone out of the hostel.

Solution :

Let, number of students left after 20 days are x.

Now, provisions are given by :

`\text{Provisions = Number of students}* \text{Number of days}`

Also, provisions remains same.

So, initial provision = final provision

`500* 4 = x * 20\\\\x=100`

Therefore, 100 students have gone out of the hostel.

Hence, this is the required solution.
