Answer 2

Answer:

Step-by-step explanation:

Let the number of girls be x

Since we are given that the number of boys is 2/5 of the girls

So, Number of boys = 2x/5

There are 42 students in total.

So, x+(2x/5)=42

7x/5=42

7x=210

x=30

Thus the number of girls is 30.

Number of boys = 2x/5=(2*30)/5=60/6=12

Thus the number of boys = 12
