GRE : Introduction to Quantitative Reasoning


The Quantitative Reasoning section of the GRE is a test of math 
concepts that you learned in seventh through tenth grades. 
This section is not just about cracking numbers. 
As the Verbal Reasoning section tests your ability to analyze words  and passages in context, similarly the QR section measures your  ability to analyze numbers. 

So, let's review what the section holds for you.

Major Quant Concepts
The GRE QR assesses your ability to deal with numbers in the following four main categories:
1. Arithmetic
2. Algebra
3. Geometry
4. Data Analysis

For detailed understanding of these topics you can visit an article on Introduction to Quantitative Reasoning section by ETS.

Most of the questions in the Quant section appear in a “word problem” format.

Question Types in the Quant section
1) Multiple Choice
This is the basic multiple choice format with five answer choices.
Example: 
The average (arithmetic mean) of seven numbers is 9 and the average of the three of these numbers is 5. What is the average of the other four numbers?
🔘 4
🔘 5
🔘 7
🔘 10
🔘 12
2) Multiple Choice with Multiple Answer
The questions appear similar to the basic multiple choice questions, however, you have to choose more than one correct answer.
Remember NO partial marking is given by ETS, so you will have to choose all correct answers to get credit for the question.
Example:
There are at least 200 apples in a grocery store. The ratio of the number of oranges to the number of apples is 9 to 10. How many oranges could there be in the store?
Indicate all possible choices.
🔘 171
🔘 180 
🔘 216
🔘 252
🔘 315

3) Quantitative Comparison
These questions consist of two columns, A and B. You have to compare the quantities of the two and choose the right answer.
Example:
A and B are points on the circumference of the circle with center O (not shown). The length of chord AB is 15.
Quantity A                                 Quantity B                                     
 Circumference of circle O12Ï€
🔘 Quantity A is greater
🔘 Quantity A is greater
🔘 The two quantities are equal
🔘 The relationship cannot be determined from the information given.
4) Numeric Entry
These questions won’t have answer choices. You have to reach an answer and then type it into the space provided. 
Example:
Each month, Renaldo earns a commission of 10.5% of his total sales for the month, plus a salary of $2,500. If Renaldo earns $3,025 in a certain month, what were his total sales?

                                                             $ ⬜
     
                               Click on the answer box and type in a number.
                                   Backspace to erase.

Data Interpretation Sets
Some questions on the GRE QR section will be a part of a set. These sets may be presented in the form of tables, pie charts, graphs or some other display.
Example:

 Approximately how many tons of aluminium and copper combined were purchased in 1995?
🔘 125
🔘 255
🔘 325
🔘 375
🔘 515
---------------------------------------------------------------------------------
Check your answers below!

1) Multiple Choice: (E) 12
2) Multiple Choice, Multiple Answer: (B), (C), (D), (E)
3) Quantitative Comparison: (A) Quantity A is greater
4) Numeric Entry: 5,000 (Just enter 5,000; no need for units).
Data Interpretation : (D) 375

P.S. Don't worry about calculations. You will get an on-screen calculator in the QR section. You will also get a scratch paper to work out your calculations.
