12

Step-by-step explanation:

1st of all we should let the ration of boys to girls be 2x and 3x.

After that we should make the sum between 2x and3*and the sum of 2numbers is equal to 30

i. e. 2x+3x=30

Then, by solving this eqation we get the value of x=6

After that put the value of x in the number of boys

i. e.

2x=2*6=12

Hence, the number of boys is 12
