Q2 of 33 Page 44

A class has the same number of girls and boys. Only eight boys were absent on a particular day and then the number of girls was double the number of boys. What is the number of boys and girls?

Let the number of girls and boys in the class be x each.

On a particular day


8 boys were absent


∴ number of boys present = x-8


Since, number of girls is twice the number of boys present on that day


x = 2(x-8)


Solving the brackets, we get


X = 2x-2 × 8


⇒ x = 2x-16


⇒ 16 = 2x-x


⇒16 = x


Hence, number of boys and girls in the class = 16 each
