120 lbs.
96 lbs.

Correct Answer: D

Explanation:

How much water must be evaporated from 240 pounds of a solution that is 3% alcohol to strengthen it to a solution that is 5% alcohol?

Alcohol in the solution = 240 × $\frac{3}{100}$ = 7.2 pounds

If 7.2 pounds = 5%, the total = 7.2/0.05 = 144 pounds

240 - 144 = 96 pounds of water to evaporate
