One fourth of a solution that was 10 percent sugar by weight was replaced by a second solution resulting in a solution that was 16 percent sugar by weight. The second solution was what percent sugar by weight ? Choose the correct choice from the following answers
A) 34% B) 24% C) 22% D) 18% E) 8.5%
Let the original solution be 100 ml   It had 10ml of sugar   1/4 of this solution is removed   sugar remaining = 7.5 ML   25 ml of x% solution is added.   New volume of sugar = 7.5+25*x/100   Since resulting solution is 16% sugar by weight, volume of sugar = 16ml   equating the 2   x=(16-7.5)*4=
