Answer :
The ratio of boys and girls = 7 : 5
Let, x be the common multiple.
So, number of boys is 7x and that of girls be 5x
Thus, total number of students
= 7x + 5x
= 12x
By the given condition,
7x = 5x + 8
or, 7x - 5x = 8
or, 2x = 8
or, x = 4
Hence, the strength of the total class
= total number of students
= 12x
= 12 × 4
= 48
