A container consists of x liters of milk. The milk in the container is adulterated by adding water equal to 50 percent of the milk in the container. If a person takes out 6 liters of the milk solution from the container, how many liters of water does he take out?

A. 1
B. 2
C. 3
D. 4
E. 5

Answer: B

Solution:

In the new solution, where the amount of water equals 50% of the amount of milk in the container, it means that the ratio of water to milk is 1 to 2; therefore, when 6 liters of the milk solution are removed from the container, 2 liters will be water, and the other 4 liters will be milk.
