if 50% of (x-y) = 30% of (x+y) then what percent of x is y?	Choose the correct choice from the following:	A) 2.5%	B) 10%	C) 5%	D) 15%	E) 25%
50% of (x-y)=30% of(x+y)   (50/100)(x-y)=(30/100)(x+y)   5(x-y)=3(x+y)   2x=8y   x=4y   therefore required percentage   =((y/x) X 100)% = ((y/4y) X 100) =25%   Answer is 25%.
