Let x denote the number of boys. Let y denote the number of girls.

A = x + y -> equation 1
B = x - y -> equation 2

Subtracting equation 2 from equation 1 we will get y = (A - B)/2 -> equation 3

Ratio of total number of girls to the total strength will be y / x + y.

Now substituting A for x + y as per equation 1 and (A - B)/2 for y as per equation 3 we will get the answer as
(A - B)/(2*(A + B))

By Putting that value in any equation
We get Girls = (A-B)/2
