Question

a class has the same number of girls and boys only 8 boys were absent on a particular day then the number of girls was double the number of boys what is the number of boys and girls

Answer 1

no. of girls=no. of boys
n 8 boys are absent so half of no. of girls
consider no. of girls =no. of boys as x
$\frac{x}{2} = 8 \\ x = 2 \times 8 \\ x = 16 \\ x + x = 2x = 2 \times 16 = 32$
no of boys and girls together is 32 and sepratly 16
