Answer:

there are13 students in the class

Answer 2

48

Step-by-step explanation:

Let,

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

 According to the question,

 $7x = 5x + 8\\2x = 8\\x = 4$

 

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

 

Therefore total strength of the class = $28 + 20 = 48$
