Answer 2

Dear Student,

◆ Answer -

3/5th students are girls.

No of boys = 110

● Explanation -

Suppose total no of students are x.

Then no of boys will be 2x/5 and no of girls will be x - 2x/5 = 3x/5. i.e. 3/5th of total.

Given that no of girls are -

3x/5 = 165

x = 165 × 5/3

x = 275 students

Now no of boys are -

2x/5 = 2 × 275 / 5

2x/5 = 110 boys

Hence, no of boys is 110.

Thanks dear. Hope this helps you...
