The number c is the by multiplying by to create the equivalent ratio.

We are given ratio of number of boys to number of girls = 8:7

On multiplying c by 8, we get 8c and on multiplying c by 7 we get 7c.

Therefore, number of boys = 8c and

number of girls = 7c.

Total number of girls and boys = 195.

Number of boys + number of girls = 195.

We can setup an equation now

8c + 7c = 195.

Adding 8c and 7c we get 15c.

Therefore 8c + 7c = 195 equation would become

15c=195.

Dividing both sides by 15, we get

15c/15 = 195/15.

c = 13.

Therefore, value of number c is 13.

Fourth option is correct.
