Data Sufficiency question Ratio HELP

Q: Number of cups of flour/Number of cups of sugar = ?

1. Number of cups of flour = 2.5 * number of cups of sugar

=> Number of cups of flour/Number of cups of sugar = 2.5 - Sufficient

2. F = 1.5 + S (F = Nu. of cups of flour, S = No. of cups of sugar)

This is not sufficient because there is no way to determine Number of cups of flour/Number of cups of sugar.

1. The number of cups of flour required in the recipe is 250% of the number of cups of sugar required. - The ratio of the number cups of flour to the number of cups of sugar = 250/100. Sufficient

2. 1 1/2 more cups of flour than cups of sugar are required. - The ratio of the number cups of flour to the number of cups of sugar = (cups of sugar + 1.5)/cups of sugar. Insufficient
