A mixture has 60 g of milk and 40 g of water. If 20 g of the mixture is removed, what is the new ratio of milk to water?

3:2
9:6
36:24:00
3:1

Correct answer: 9:6

Solution

The original ratio of milk to water is 60:40 = 3:2. In 20 g of the same mixture, milk removed = 12 g and water removed = 8 g, leaving 48 g milk and 32 g water. The new ratio is 48:32 = 9:6.
