The number of boys in the class is 12

The number of girls in the class is 20

Step-by-step explanation:

Given as :

The ratio of boys to girls in school classroom = 3 : 5

The Total number of students in class = 32

Let The number of boys in class = 3 x

And The number of girls in class = 5 x

According to question

The Total number of students in class = The number of boys in class + The number of girls in class

Or, 3 x + 5 x = 32

Or, 8 x = 32

∴   x =

I.e x = 4

So, The number of boys in class = 3 x = 3 ×4 = 12

And The number of girls in class = 5 x = 5 ×4 = 20

Hence The number of boys in the class is 12

And The number of girls in the class is 20   Answer
