Question

# In a school, 𝑡ℎ of the students are boys, if there are 240 girls, find the number of boys in the school?

Hint:

### Find the total number of students and then subtract number of girls from it to

get the total number of boys.

## The correct answer is: 400

### Let the total number of students = x

Number of girls = 240

So, number of boys = x - 240…(i)

Given that of the total students are boys. That is, …(ii)

On equating (i) and (ii) , we get

Multiply by 8 on both sides.

We have

Hence total number of students = 640

From (ii), we get total number of boys

So, number of boys in the school = 400
