Question

The number of boys and girls in a class are in ratio 7:5. The numbers of boys is 8 more than one number of girls. What is the total class strength

Answer 1

Answer:

48

Step-by-step explanation:

let the number of boys in the class be 7x and the number of girls be 5x.

we know that the number of boys is 8 more than the number of girls.

therefore,

7x = 5x + 8

2x = 8

x= 4

substituting the value of x, we get,

number of boys: 7x = 7(4)

                                = 28 boys

number of girls: 5x = 5(4)

                                = 20 girls

therefore,

the class strength=  28 + 20= 48

hence, the class strength is 48.

Hope this helps you!
