Problem 11 - Entrance Test

A recipe calls for a ratio of 3:4 of flour to sugar. If you need 12 cups of flour, how many cups of sugar do you need?

Correct: B

The ratio of flour to sugar is 3:4. If you need 12 cups of flour, which is 4 times 3, you need 4 times 4 cups of sugar. So, 4 * 4 = 16 cups of sugar.
