Question

In a class of 40 children, the ratio of the number of boys to the number of girls is 2:3. How many more boys are needed to make this 3:2 ​

Answer 1

Step-by-step explanation:

Number of boys in the class = 2/5 × 40

= 16

Hence, the number of girls = 40-16 = 24

Therefore, in order to make the ratio of boys to girls 3:2,

So, 20 more boys are required to make the ratio of boys to girls 3:2

(36/24)=(3:2)

NOTE :-

This is the case where we cannot change the number of girls.

If we are flexible with removing girls, then 8 boys will be added.
