Answer 1

Answer:

so what we have to find in it??

Answer 2

Answer:

Number of girls = 30

Number of boys = 12

Step-by-step explanation:

Let boys be x and girls be y.

x+y=42

y=5/7*42

y=5*6

y=30

Therefore number of girls will be 30.

Number of boys= Total Number of Students - Number of girls

                          = 42 - 30

                          = 12
