How many liters of pure alcohol must be added to a 100-liter solution that is 20 percent alcohol in order to produce a solution that is 32 percent alcohol?
Choose the correct choice.
A) 7/2	B) 5	C) 20/3	D) 8	E) 300/17
20% Alcohol solution means; in the 100 liter solution, 20 liters of solution is alcohol and 80 liters other solvents.   If we addxliters of alcohol to the solution, the solution becomes100+xliters and alcohol, which was 20 liters, becomes 20+x liters.   According to the statement;   20+x = 32% of (100+x)   OR   20+x=(100+x)8/25   500+25x=800+8x   17x=300   x=300/17   Ans:300/17
