Answer 2

HEY!!

HERE IS YOUR ANSWER,

This can be solved by cross multiplication method.

But, first, let’s solve for boys:

If 60 boys =============> 60% of the class

Then, X kids ==========> 100% of the class

> 100 x 60 = 60X

> 6000 = 60X.

Then,

> X = 6000 / 60 = 100 kids

Therefore, total no. of kids in the class = 100.

HOPE IT HELPS YOU,

THANK YOU. ^_^
