One fourth of a solution that was 13% salt 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 salt by weight?  Choose one:  A) 25%  B) 34%  C) 22%  D) 18%  E) 8.5%
consider total solution to be 100 liters and in this case you'll have: 75*0.13+25*x=100*0.16 --&gt; x=0.25.   25%nswer: 25%.
