INTRODUCTION
Congratulations! You’ve taken a big step toward GRE® success by purchasing
McGraw Hill 500 GRE Math Questions to know by test day. We are here to help
you take the next step and score high on your GRE exam so you can get into the
graduate school of your choice!
This book gives you 500 updated GRE-style questions that cover all the most
essential course material in the Quantitative Reasoning section. Each question is
clearly explained in the answer key. The questions will give you valuable indepen-
dent practice to supplement your earlier studies.
This edition also features our 20-question GRE Quantitative Reasoning
diagnostic quiz at the beginning of the book to test your knowledge upfront.
Designed to represent the different topics covered on the GRE, it can give you a
head start on learning what you know and what you need to improve upon.
The math questions in the Quantitative Reasoning section of the computer-
based GRE revised General Test are presented in two 35-minute sections, consist-
ing of 20 questions per section. The questions test your knowledge of and skills in
arithmetic, elementary algebra, basic geometry, and data analysis and your ability
to reason analytically and solve math problems in context. You are allowed to skip
questions, move back and forth, and change answers within a section. You also
have access to an on-screen basic calculator.
Four question types are presented in the Quantitative Reasoning section:
quantitative comparison questions, multiple-choice questions (select one answer
choice), multiple-choice questions (select one or more answer choices), and
numeric entry questions. Quantitative comparison questions require you to com-
pare two quantities and then decide whether one is greater, whether the two
quantities are equal, or whether the relationship cannot be determined from the
given information. Multiple-choice questions (select one answer choice) pres-
ent five answer choices from which you must select the one best answer choice.
Multiple-choice questions (select one or more answer choices) present a list of
choices from which you must select one or more answer choices, as specified in
the question. Numeric entry questions are open-ended questions in which you
enter your answer in an answer box.
This book and the others in the series were written by expert teachers who know
the subject inside and out and can identify crucial information as well as the kinds
of questions that are most likely to appear on the exam.
You might be the kind of student who needs to study extra a few weeks before
the exam for a final review. Or you might be the kind of student who puts off
preparing until the last minute before the exam. No matter what your preparation
style, you will benefit from reviewing these 500 questions, which closely parallel the
content, format, and degree of difficulty of the questions on the actual GRE exam.

on the Quantitative Reasoning section of the GRE and, further, are designed to

ematics behind the question.
Note: Unless otherwise stated, you can assume all of the following.
All numbers used are real numbers. All figures lie in a plane and are drawn accu-
rately, but are not necessarily drawn to scale. Lines shown as straight are straight
lines. The relative positions of points, angles, and regions are in the order shown.
Coordinate systems, such as number lines and xy-planes, are drawn to scale.
Graphical displays of data, such as bar graphs and frequency distributions, are
drawn to scale.
Directions for Questions 1 through 5: Compare Quantity A and Quantity B
using all the information given. Then select one of the answer choices that follow
the question.
1. Quantity A Quantity B
1(57)25 19(57)24
