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

Answer

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
