Chapter 7 - Mixed Practice Sets

Practice Set 3

This chapter contains three sets of practice questions. Each set has 25 questions, with a mixture of content and question types.

Practice Set 1

The questions for Practice Set 1 are in the document titled, “GRE Chapter 7 Set 1 Questions.doc.” The answer key and the explanations are in the separate document titled “GREChapter 7 Set 1 Answers and Explanations.doc.”

Practice Set 2

The questions for Practice Set 2 are in the document titled, “GRE Chapter 7 Set 2 Questions.doc.” The answer key and the explanations are in the separate document titled “GREChapter 7 Set 2 Answers and Explanations.doc.”

Practice Set 3

The questions for Practice Set 3 are in this document. The answer key and the explanations are in the separate document titled “GRE Chapter 7 Set 3 Answers and Explanations.doc.”

Each of the Practice Sets in this chapter has 25 questions which are arranged by question type: Quantitative Comparison questions, followed by both types of Multiple-choice questions, then by Numeric Entry questions, and ending with a Data Interpretation set. Review the answers and explanations carefully, paying particular attention to explanations for questions that you answered incorrectly.

Note that each set of 25 practice questions has about the same number of questions of each type as the individual Quantitative Reasoning sections in the paper-based GRE revised General Test, with 25 questions per 40-minute (Standard Time) section. Therefore, to help you gauge the timed aspect of the Quantitative Reasoning measure, it may be useful to set aside a 40-minute (Standard Time) block of time for each set of 25 questions.

Before answering the practice questions, read the Quantitative Reasoning section directions that begin on the next page. Also, review the directions that precede each question type to make sure you understand how to answer the questions.

Quantitative Reasoning Section Directions

Directions: For each question, indicate the best answer, using the directions given.

Notes: All numbers used are real numbers.

All figures are assumed to lie in a plane unless otherwise indicated.

Geometric figures, such as lines, circles, triangles, and quadrilaterals, are not necessarily drawn to scale. That is, you should not assume that quantities such as lengths and angle measures are as they appear in a figure. You should assume, however, that lines shown as straight are actually straight, points on a line are in the order shown, and more generally, all geometric objects are in the relative positions shown. For questions with geometric figures, you should base your answers on geometric reasoning, not on estimating or comparing quantities from how they are drawn in the geometric figure.

Coordinate systems, such as x y-planes and number lines, are drawn to scale; therefore, you can read, estimate, or compare quantities in such figures from how they are drawn in the coordinate system.

Graphical data presentations, such as bar graphs, circle graphs, and line graphs, are drawn to scale; therefore, you can read, estimate, or compare data values from how they are drawn in the graphical data presentation.

Quantitative Comparison Questions

For Questions 1 to 9, compare Quantity A and Quantity B, using the additional information given, if any. Select one of the following four answer choices.

A. Quantity A is greater.

B. Quantity B is greater.

C. The two quantities are equal.

D. The relationship cannot be determined from the information given.

A symbol that appears more than once in a question has the same meaning throughout the question.

Example 1:

Quantity A: 2 times 6

Quantity B: 2+6

Solution: Quantity A is equal to 12 and Quantity B is equal to 8, so the correct answer for Example 1 is answer choice A, Quantity A is greater.

Example 2:

Refer to the figure.

Figure for Example 2

Begin skippable part of figure description.

The figure for example 2 shows triangle PQR where P is the leftmost vertex of the horizontal base PR and vertex Q is above PR. Point S lies on horizontal base PR and appears to be the midpoint of PR. Line segment QS is drawn from vertex Q to point S. The lengths of PS and SR appear to be equal.

End skippable part of figure description.

Quantity A: The length of PS

Quantity B: The length of SR

Solution: The correct answer for Example 2 is answer choice D. The relationship between the lengths of PS and SR cannot be determined from the information given since equal measures cannot be assumed, even though the lengths of PS and SR appear to be equal in the figure.
