Answer 1

Answer:

Let,

The number of boys 7x and the number of girls -5x.

According to the condition,

7x = 5x + 8

2x = 8

X = 4

Therefore The number of boys = 7x7 x 4 = 28 and the number of girls 5x = 5 x 4 20.

Therefore total strength of the class 28+ 20 = 48

Hope this helps ya!

Answer 2

ANSWER :

ratio of boys and girls = 7:5

boys = 7x

girls = 5x

difference between boys and girls = 8

then we can take the number of boys as 5x + 8 ,

7x = 5x+8

7x-5x=8

2x=8

x=8/2=4

X=4

we get it .

number of boys 7x = 7 × 4 = 28

number of girls 5x = 5 × 4 = 20

total students 12x = 12 × 4 = 48

CHECK IT IS CORRECT :

difference = 8

28-20=8

28:20 = 7:5

it is a correct answer
