Answer 2

Answer:

Number Of Boys = 16

and

Number Of Girls = 16

Step-by-step explanation:

Let the number of boys be 'x'.

Let the number of girls be 'y'.

Number of girls and boys are equal, i.e.

x = y_____'i'

When boys are 8 less (since, they are absent) then number of girls get doubled, i.e.

2(x - 8) = y

--> 2x -16 = y__'ii'

SUBSTITUTING 'i' in 'ii'

2x - 16 = x

--> 2x - x = 16

--> x = 16___'iii'

SUBSTITUTING 'iii' in 'i'

y = 16___'iv'

FROM 'iii' and 'iv'

Number Of Boys = 16

and

Number Of Girls = 16
