The ratio of milk and water in a mixture is 2:1,
Let milk = 2 liters and water = 1 liter.
Some quantity of water is added to the mixture to make the ratio of milk and water in the new mixture 1:2.
Since the resulting amount of water must be double the original 2 liters of milk, the resulting amount of water = 4 liters.
The quantity of water added to the original mixture is what percent of the quantity of water in the original mixture?
Since the water increases from 1 liter to 4 liters, the amount of added water = 4-1 = 3 liters.
(added water)/(original water) * 100 = (3/1) * 100 = 300%,
The correct answer is
C.
