Number of boys and girls in a class are in the ratio 7 : 5. The number of boys is 8 more than the number of girls. The total class strength is
Let the number of girls and boys be 5x and 7x respectively
According to the question
7x = 8 + 5x

⇒ x = 4
Boys = 7x = 28
Girls = 5x = 20
Total strength = 20 + 28 = 48
