How many liters of water must be evaporated from 50 liters of a 3-percent sugar solution to get a 3-percent solution? Choose one.
A) 35	B) 33 1/3	C) 27	D) 16 2/3	E) 19.5
How many liters of water must be evaporated from 50 liters of a 3-percent sugar solution to get a 3-percent solution?   3% of a 50 liter solution is 1.5L. So you are trying to determine how many liters must a solution be for the 1.5L to represent 3% of the solution. Set up an inequality and solve for x:   1.5/x = 1/3   x = 4.5   Since you need a 15L solution, you must evaporate 19.5 of the original 50L solution to get a 3% solution.   Answer is 19.5.
