Section 3: Quantitative

Time: 75 minutes

37 questions

This section consists of two different types of questions: Problem-Solving and Data Sufficiency. To answer the questions, select the best answer from the answer choices given.

The Problem-Solving questions require you to solve the problem and select the best answer choice.

Numbers: All the numbers used are real numbers.

Figures: A figure given for a question provides information that can be used to solve the problem. Figures are drawn to scale, as accurately as possible, unless it is stated otherwise. A line that appears straight should be considered a straight line. All figures given in this section lie in a plane unless it is stated otherwise.

Each Data Sufficiency problem contains a question followed by two statements, (1) and (2). You are asked to determine whether the statements are sufficient to answer the question. You need to use the information given in the statements along with your knowledge of general mathematics and other common facts (such as the number of minutes in an hour or the number of days in a year) to determine which of the following is true:

  1. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question.
  2. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question.
  3. BOTH statements (1) and (2) TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
  4. EACH statement ALONE is sufficient to answer the question.
  5. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question, and additional data specific to the problem is needed.

In any Data Sufficiency problem that asks for the value of an unknown quantity, the statements are sufficient to answer the question only when you can determine exactly one value.
