Coca Cola contains 75% water (GMAT Mixture Problem)

Coca Cola contains 75% water and 25% soda; how many more liters of water than liters of soda are in 200 liters of Coca Cola?

A. 50
B. 100
C. 125
D. 150
E. 175


For water, 75% of 200 liters is 150 liters of water: (200 liters)(0.75 water concentration) = 150 liters of water.

For soda, 25% of 200 liters is 50 liters of oil: (200 liters)(0.25 soda concentration) = 50 liters of soda.

The difference between the two is 150-50, which equals 100 liters.

Correct Answer - Choice B
