Answer:

48 students are there in class.

Step-by-step explanation:

Let,

The number of boys = 7x

The number of girls =5x.

According to the condition given in the question,

7x = 5x + 8

2x = 8

x = 4

Therefore,

The number of boys = 7x = 7 × 4 = 28

The number of girls =5x = 5 × 4 = 20.

Hence,

Total strength of the class = 28 + 20 = 48

7x+8=5x
7x-5x=8
2x=8
X=8/2=4
