Answer 2

Answer:

Step-by-step explanation:

Assume number of girls is X. So number of boys is (X+10)

The ratio of boys to girls is 5/3

Let's try to now set up our equation:

Boys/Girls=(X+10)/X=5/3

I.e. 3*(X+10)=5*X

I.e. 3X + 30 = 5X

I.e. 30 = 5X-3X=2X

I.e.30/2=X

I.e.15=X

So number of girls = 15

And number of boys =15+10=25

And total number of people = 15+25=40
