Question

If 480 pupils in a school are boys representing 4/5 of the school enrolment,find the total number of pupils in the school​

Answer 1

1000

Explanation:

Let the total number of children in school be y.

Then according to the question (4/5) of children are boys.

Then as we know that the sum of fractions is 1.

The fraction of girls in school is

1 - (4/5)= (1/5)

So this means (1/5) of the total children in school are girls which means

Y × (1/5) =200 , according to question.

Which gives y =200×5=100

This means that the total number of children in school is 1000.
