Hi Meghana,
Let the initial number of boys and girls be x and y respectively.
It is given,
40x+60y/x+y = 45
5x = 15y
x = 3y
It is also given that,
40(3y) + 640 + 60y/4y + 8 = 52
Solving, we get y = 8 and x = 24
Therefore, the number of boys and girls initially is 24 and 8, respectively.
Hope this helps!
