Answer 1

Answer:

no of girls=14

no of boys=21

Answer 2

Answer:

There are 25 boys in the class

Step-by-step explanation:

The prior thing in this sum is to find out the linear equation.

Given, Total Number of Students= 35

           Number of girls among them= 2/5 of the number of boys.

Let the number of boys be x.

Then the number of girls=2x/5

Hence, 2x/5+x=35

          =>7x/5=35

          =>x=35*5/7

          =>x=25

Hence, there are 25 boys in the class.

This can be cross-verified as,

No.of boys=25

No.of girls=2*25/5=10

Total no.of students=25+10=35
