if 50% of (x-y) = 20% of (x+y) then what percent of x is y?	Choose the correct choice
A) 2.5% B) 10% C) 5% D) 15% E) 43%
50% of (x-y)=20% of(x+y)   (50/100)(x-y)=(20/100)(x+y)   5(x-y)=2(x+y)   3x=7y   x=7/3y   therefore required percentage   =((y/x) X 100)% = ((y/(7/3)y) X 100) =43%   Answer is 43%.
