Of the 28 mathematics questions on the GRE, 10 are standard multiple-choice questions, what the ETS calls discrete quantitative questions. The way to answer such a question is to do the necessary work, get the solution, and then look at the five choices to find your answer. Now let’s look at two examples.
Discrete Quantitative Questions Example No. 1
To solve this problem requires only that you understand what a ratio is. Ignore the fact that this is a multiple-choice question. Don’t even look at the choices.
· Let 4x and 3x be the number of students taking and not taking Spanish, respectively.
· Then 4x + 3x = 840 => 7x = 840 => x = 120.
· The number of students taking Spanish is 4 x 120 = 480.
· Having found the answer to be 480, now look at the five choices, see 480 listed as Choice C, click on that choice, and confirm your answer.
Another type of multiple-choice question that appears on the GRE is the Roman numeral-type question. These questions consist of three statements labeled I, II, and III. The five answer choices give various possibilities for which of the statements are true. Here is a typical example.
Discrete Quantitative Questions Example No. 2
To solve this problem, examine each statement independently, and think of it as a true-false question.
