Question

The number of boys and grils in a class are in ratio 7:5 ,the numbersog boys is 8 more then the numbers of grils what is the total class strength?

Answer 1

Step-by-step explanation:

Let the number of boys be 7x and that of girls be 5x.

According to the given condition:

no. of boys = no. of girls + 8

Therefore,

7x = 5x + 8

7x - 5x = 8

2x = 8

x = 4

no. of boys = 7x = 7*4 = 28

no. of girls = 7x = 5*4 = 20

Total class strength = 28 + 20 =48
