The** Boys Count in Class Problem** is as follows :

**Question :**

A Class has 90 students. If the ratio of boys and girls is 7:8, find the number of boys in the class.

**Solution :**

Now we know that the entire class gets divided into the ratio of 7:8 .

Now 7 + 8 = 15 . So that means out of every 15 students, 7 are boys and the remaining 8 are girls.

Hence this means that (7/15) th of the class is boys.

So (7/15) X 90 = 42.

Hence the number of boys is **(b) 42 **
