Answer 2

Answer:

total strength of class is 60

Step-by-step explanation:

Let the common multiple be x

No. of Boys = 7x

No. of girl = 5x

According to the question

7x = 5x +8

7x - 5x = 8

2x = 8

x = 8

2

x= 4

so , No. of boys = 7 × 5

= 35

No. of girls = 5 ×5

= 25

the strength of class = 35 +25 =60
