if 50% of (x-y) = 40% of (x+y) then what percent of x is y?
Select the correct option:  A) 2.5%  B) 11%  C) 5%  D) 15%  E) 25%
50% of (x-y)=40% of(x+y)   (50/100)(x-y)=(40/100)(x+y)   5(x-y)=4(x+y)   x=9y   x=9y   therefore required percentage   =((y/x) X 100)% = ((y/9y) X 100) =11%   Answer is 11%.
