Answer 2

Answer:

48

Step-by-step explanation:

Difference between ratio = 7-5 = 2

Difference between number of boys and number of girls = 8 = 4×2

If total strength of class = 7+5 = 12, then number of boys is 2 more than number of girls.

If total strength of class = 7×4 + 5×4 = 48, then number of boys is 8 times number of girls.

Thus, total class strength = 48
