The ratio of flour to water to sugar in a recipe is 7:4:1. The ratio in a new recipe calls for a doubling of the ratio of flour to water from the original recipe and a halving of the ratio of flour to sugar. If the new recipe calls for 8 cups of water, how much sugar is required?

(A) 4 cups

(B) 6 cups

(C) 8 cups

(D) 12 cups

(E) 16 cups

Hello,

Flour/Water = 7/4, Flour/Sugar = 7/1

Double the ratio of Flour/Water = 7/4 * 2 = 7/2

Halve the ratio of Flour to Sugar = 7 * 1/2 = 7/2

The new ratio of Flour: Water: Sugar = 7:2:2

For 8 cups of water in the new recipe, sugar required will be 8 cups.

Answer is C

Hope this helps
