Your model is inaccurate. A and B should have the same 1u and A has extra. Then the after model, 90 boys are moved so B would be 1u-90 and A is 1u+extra+90. Try to draw again?

The after models do not have a great proportion because of bad estimation, but i hope you understand better.
For such questions, you should try before and after models.
