GRE Sample Test 1 Quantitative Reasoning 1

The punch is made with two parts soda and three parts ice cream. This means that in one mixture if you added two parts of soda, then that’s 4 × 2 = 8 parts sugar and 5 × 2 = 10 parts citric acid. If you added three parts ice cream, then that’s 3 × 3 = 9 parts sugar and 2 × 3 = 6 parts citric acid. There’s 8 + 9 = 17 total parts sugar and 10 + 6 = 16 total parts citric acid. There’s more sugar than citric acid. Choice (A) is correct.
