The GRE Quantitative Reasoning section tests your basic mathematical knowledge (understanding of high-school level mathematical concepts) and your ability to interpret and solve problems using quantitative methods. The questions asked in this section are either placed in real-life settings or based on pure mathematics. However, even if you are not good with numbers, you can easily score high in this section if you revise and practice your elementary level mathematics.
The Quantitative Reasoning section is divided into two sections with four question types. Having a basic overview of the GRE Quantitative Reasoning will help you know the concepts asked and the questions you can expect in the GRE. Let’s take a look at the same.
GRE Quantitative Question Types:
There are four types of questions asked in the GRE quant section. The questions could be in any form, such as word problems or numeric problems. Here’s a brief overview of each question type.
- Quantitative Comparison Questions – Each question presents two quantities with or without a short description regarding the quantities. You must analyze each quantity, compare them and select the best option from the answer choices.
- Multiple-choice Questions (Select One Answer) – These questions present a problem (word problems, equations and more) and five answer options. These are classic MCQ questions, where you have to solve the problem and select one answer.
- Multiple-choice Questions (Select One or More Answer) – Unlike the classic MCQ questions, this type of question requires you to choose all the possible correct answers from the options. Though some questions specify how many answers to pick, others leave that up to you. Besides, you will only get credit if all your selected answers are correct.
- Numeric Entry Questions – Numeric Entry Questions have no answer options. Instead, each question presents two boxes, wherein you have to type the correct answer. If your answer is an integer or a decimal, you must type it in a single box, and if it is a fraction, you’ll be given two separate boxes (for the numerator and one for the denominator).
Additionally, the GRE Quantitative Reasoning consists of a set of questions called the Data Interpretation, wherein you have to interpret the given data and choose the best possible answer choice. All the questions in this set are based on the same data, that is presented in the form of tables, graphs or any other data representation. The questions asked could be in any format like Multiple-choice (both types) or Numeric Entry.
GRE Quant Concepts:
The GRE quant questions are mainly asked from high-school level math concepts such as arithmetic, algebra, geometry, and data interpretation. Let us have a brief look at the topics that come under each concept.
- Arithmetic – Types of integers (divisibility, prime numbers, remainders etc) exponents and roots, estimation, percentage, the number line, sequence of numbers, ratio, decimal representation etc.
- Algebra – Rules of Exponents, Solving Linear Equations, Solving Quadratic Equations, Solving Linear Inequalities, Coordinate Geometry Graphs of Functions etc.
- Geometry – Parallel and perpendicular lines, triangles (all types), quadrilaterals, polygons, three-dimensional figures, the Pythagorean theorem, area, volume etc.
- Data analysis– Mean, standard deviation, mode, interquartile range, median, quartiles and percentiles, interpretation of data in multiple formats, basic probability, combinations, permutations etc.
Quantitative Reasoning Questions:
Practice is the key to ace the GRE math section. Though a lot of topics are tested in this section, you can easily get a good score by solving the sample questions. To begin with, here are two GRE quantitative questions and their answers. You can find similar questions and answers on the official website of GRE.
- Shopkeeper sells goods at a Certain Price and makes a loss of 8%. If he would have increased the selling Price by Rs 900 he could have gained 7% from the transaction. Find the Actual Cost of the Article?
Let us Assume the Cost Price be Rs 100
So while Selling the Person Makes a Loss of 8 %
Loss of 8% on Rs 100 = Rs 8.
So the Selling Price = Cost Price – Loss
Selling Price = 100 – 8 = Rs 92
If he adds Rs X with the Current Selling Price he Gains 7%. i.e., 7% Profit on Cost Price.
profit = Rs 7 on Cost Price of Rs 100.
Therefore Selling Price + Rs X = 107
Selling Price = 92 Rs
Therefore Rs X = 15
But we Rs X was Rs 900 (given in Question)
So we assumed CP is 100 which corresponds to 100% of the Value
So if 15% Corresponds to Rs 900
Then 100% Corresponds to?
900 x 100/15 = Rs 6000(Cross Multiplication)
Hence Option D) 6000 is the Answer i.e. The Cost Price of the Article.
- A rectangular box is 10 inches Wide, 10 inches long & 5 inches high. What can be the greatest possible Distance, in inches, between any two points?
There can ‘n’ no. of Points on the body and as it’s a Rectangular Box which is also called a Cuboid.
So which 2 points are the Farthest or at the maximum Distance?
Best way to answer such a question is to Draw the Diagram or visualize.
Let a, b and c be the 3 measurements of the box as already given in the question
Hence the points which are the body diagonal would be the furthest.
So from one topmost Corner to the bottom most corner is called a Body Diagonal and on one face is called a Face Diagonal.
So, what would be the Length of Body Diagonal?
Length of Face Diagonal (Pythagoras Theorem): 10^2+ 10^2+ 5^2 .
So Again Body Diagonal would be =15
Hence Option D is the Answer.
So now, you have a clear idea of what GRE quant topics you need to emphasise on and the kind of questions you will be asked, start practicing. A high score in the math section creates a great impact on your overall GRE score. Hence, keep all the above information in mind, strategise and give it your best. Good luck!
