A 20-liter mixture contains milk and water in the ratio 3:2. If 5 liters of the mixture are replaced with 5 liters of water, what is the new ratio of milk to water?

✓ Correct Answer: Option B

Initially, milk = (3/5)*20 = 12L, water = (2/5)*20 = 8L. Removing 5L mixture means (3/5)*5 = 3L milk and (2/5)*5 = 2L water are removed. Remaining: milk = 12-3=9L, water = 8-2=6L. Adding 5L water makes new water = 6+5=11L. New ratio of milk to water is 9:11.
