One fourth of a solution that was 22% sugar by weight was replaced by a second solution resulting in a solution that was 35 percent sugar by weight. The second solution was what percent sugar by weight?	Pick one:
A) 74%  B) 24%  C) 22%  D) 18%  E) 8.5%
Say the second solution (which was 1/4 th of total) was x% sugar, then 3/4*0.22+1/4*x=1*0.35 --&gt; x=0.74. Alternately you can consider total solution to be 100 liters and in this case you'll have: 75*0.22+25*x=100*0.35 --&gt; x=0.74.   74%nswer: 74%.
