Question: A mixture contains 30% sugar and 70% water. If 5 liters of the mixture is taken out, how much sugar is left in the mixture?
Options:
Correct Answer: 2.5 liters
Solution:
In 5 liters of the mixture, sugar = 30% of 5 = 1.5 liters. If the original mixture was 5 liters, the remaining sugar = 30% of (original volume - 5) = 30% of (5 - 5) = 0 liters. Thus, 1.5 liters of sugar is removed, leaving 0 liters.
