GRE Quantitative Practice Questions — Quantitative Comparison Format

Here you'll find a series of eight GRE Quantitative Comparison practice questions (where you compare two quantities and decide which, if either, is greater). You'll probably find earlier questions to be simpler and easier than later ones.

NOTE: On the actual GRE exam, each Quantitative Reasoning section will include several questions in this format. They'll be mixed with multiple-choice and Numeric Entry questions.

Instructions for Practice Questions:
  1. Review the test directions (below).

  2. Go to any of the numbered practice questions. You can select an answer choice by clicking on a button.

  3. Scroll down the page for the correct answer and an analysis of the question. Click on "Directions" to return to this page.

  4. This is not a timed test. But if you want to simulate timed testing conditions, limit yourself to 1¾ minutes per question, on average.

Compare Quantity A and Quantity B. Use additional, centered information (if any) to make the comparison. Select one of four answer choices:

    A. Quantity A is greater.

    B. Quantity B is greater.

    C. The quantities are equal.

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

NOTE: Any symbol appearing more than once in a question has the same meaning throughout the question.


All numbers used are real numbers.

All figures lie on a plane unless otherwise indicated.

All lines shown as straight are straight.

All angle measures are positive.

Figures are intended to provide useful information for answering the questions. However, unless a figure is accompanied by a "Note" stating that it is drawn to scale, answer the question using your knowledge of mathematics and not by visual measurement or estimation.
