Introduction to Quantity comparison questions:

Each Quantitative Section in GRE contains about 7 Quantitative Comparison questions. As the name suggests ,  in these questions you need to compare two quantities mathematically and mark an answer accordingly. Also this a type of question not a topic , so you can get a quantity comparison question on any of the math topics( such as geometry , statistics etc ).

Since 35 percent of quantitative section constitutes of quantity comparison questions , it is very important to learn some strategies that can help students to solve these questions in lesser time and with better accuracy.

Format :

These questions have a very specific format : ‘column A’ and ‘column B’, each column containing numbers of variables. Often, you’ll get additional information about the variables. You will then have to choose one of the following 4 answers:
1. The quantity in column A is greater
2. The quantity in column B is greater
3. The two quantities are equal
4. The relationship cannot be determined from the information given

This might sound a bit confusing, but it’s pretty straightforward- all you need to do is analyze the information in both the columns and decide whether column A or B contains a larger quantity.Sometimes you are not able to compare the columns using given information or you end up getting more than one relation between the two columns , in that case D is your answer, and sometimes both the quantities are equal, so you’ll answer C. Check the following link to understand the questions in detail


1. Know the format of questions and order of answer options

2. If you encounter a complex comparison than try and simplify that by applying the same operations to both columns. For example: you can multiply or divide both the columns by a same term or same number.

3. Focus on the information( if any) centred between the two columns.

4.  In case of variables in the questions consider what happens if you choose positive versus negative values, odd versus even values, and integer versus fractional values.

5.  ETS generally tests your knowledge of equations,  numbers  ,  geometry and arithmetic .

6.  Do plug in numbers into expressions with variables and if you get different results, than answer is D. Use FROZEN to choose numbers:

F- Fractions
R-Repeats ( Numbers present in  the questions)
E-Extreme( Maximum and Minimum value a variable can take)

7.  Do not trust the geometric figures in comparison questions as they are never drawn to scale.

8.  Calculate to compare not to solve. Don’t do needless calculations . STOP when you get the comparison.

9.  Use FROZEN to consider all the possibilities in case of unknowns or variables.

10.  Don’t confuse percent and numbers.

11.  Estimate or Ballpark: Since there is no negative marking for an incorrect answer in GRE exam , it’s always better to ballpark and mark an answer.

12.  Use hints and mark Reasonable answers.

13.  Boundary condition helps us a lot

Quantity comparison questions are tricky and in order to score a 165+ in math section you need to avoid the TRAP answers. Also 14 out 40 scored questions would be quantity comparison questions so they are as important as any other type and require as much practice as Problem solving or Data interpretation questions.

Best of luck!!

CityXfer saves your time and let you focus on your preparations

In this post, we will be covering an exciting startup - CityXfer. Though this is not related to GRE, but we are excited about this young company for three reasons - firstly, they are solving a very pertinent problem of delivering any type of item on the same day; secondly, we've had a first hand experience of their top class product & service; and thirdly, CityXfer has been started by our friend Kumar Gaurav who, like us is a geek & problem solver to the core.

So here is what CityXfer does - at times, we have to leave our office work or family to do mundane tasks of delivering items like documents or clothes or something bigger like furniture etc. This eats up our precious 3-4 hours and we feel we could have utilized this time better like finishing that presentation or watching a movie or playing with our kids or taking a mock test, of course! CityXfer comes across as a respite in such situations. Their delivery executives will pickup & deliver the item from your doorstep to the destination on the same day. Their pricing also fits into the pocket. They are seeing amazing early traction in Bangalore and we believe they are upto something big.

If you are an individual or a small business, just head to their Website or Android App or call them to checkout their delivery services.

Team WiseSwan wishes CityXfer good luck :)
