How many liters of water must be evaporated from 50 liters of a 3-percent sugar solution to get a 20-percent solution?
Choose the correct choice from the following answers:
A) 45
B) 33 1/3
C) 27
D) 16 2/3
E) 15
How many liters of water must be evaporated from 50 liters of a 3-percent sugar solution to get a 20-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 20% of the solution. Set up an inequality and solve for x:   1.5/x = 1/20   x = 30   Since you need a 15L solution, you must evaporate 45 of the original 50L solution to get a 20% solution.   45nswer is 45.
