In this blog post, we shall be focusing on the quantitative aptitude section for RBI Grade B. 

The Quantitative Aptitude section of RBI Grade B is somewhat more difficult than the other banking examinations; in general, one can expect moderate-hard level questions in the section or any topic from it. However, some topics in the QA section of RBI Grade B have more questions coming from them in the exam than others; anyhow, the topic-wise preparation strategy for RBI Grade B Quantitative Aptitude.


Simplification is one of those topics in Quantitative Aptitude which is quite important from the exam point of view. If you look at the RBI Grade B Past Years Papers, you will see that it is an important chapter that cannot be ignored. Simplification could target as much as 15-20% of the total number of questions in the Quant section.

  • When you are revising, start with Simplification or keep it in the earliest of chapters for revision
  • There are many topics in which you will need to be good with mental mathematics. It is not necessary, but it helps, so while practicing, try to compute simple calculations in your memory.
  • Among simplification, the majorly important topics are percentages, squares and cubes, surds and indices, etc. Ensure that you are thorough with each of them.

Number Series

While number series might take some time to master, they are easily answered/attempted when they have become familiar. However, the major challenge here is to identify the patterns in the number series question. Devote no more than half a minute to attempting them; beyond that, it is a waste of time and you might get the answer wrong most likely. Having said that –

  • Practice as many number series questions as you can. The idea is to become more comfortable with various kinds of questions
  • While practicing, take notes regarding what you find to be important for each pattern or anywhere you think you can go wrong
  • Oliveboard’s topic tests can help you determine whether you have understood the patterns correctly/well or not, but ensure that you analyse the results

Data Interpretation (DI)

Banking examinations rely heavily on data interpretation and data sufficiency and RBI Grade B is no exception. DI should be practiced every single day, even if 1 question is all that is being practiced or attempted. Additionally, to do well in the topic, you need to take care of the following:

  • Practice is essentially important in this topic, because you need to be familiar with the kind of DI question that is presented.
  • Start by looking at the diagram and understanding what it provides and then move on to the question. That way you can connect the information that exists for both the diagram and the question.
  • Data interpretation questions are not as hard as they look. The challenge is to however not get worried but the huge amount of information they include, much of which is not usually needed to answer the questions.

Quadratic Equations

Another important topic in the RBI Grade B Quantitative Aptitude is quadratic equations. Quadratic equations are important because like simplification, they have a good number of questions allotted to them in the examinations. However, unlike some other, trickier topics, it is possible to solve quadratic equations easily if you can remember the formula associated with them.

  • It is not enough to know the formula; you should also know how to apply the same. To do that, only practicing correctly will help.
  • Quadratic equations are relatively straightforward questions, but it helps to keep a track of the various ways they could be asked in the exam. You can do so by preparing your own notes wherever you think necessary.
  • Revision should be done from your notes strictly. This will help you save time and only focus on what’s important.

Profit and Loss

Profit and Loss is one of the relatively easier topics in quantitative aptitude, and although it does not have many questions in the RBI Grade B exam (as the topic is simple), you should still not ignore it, because even 1 correct answer can save your luck in the examination. There are no direct ways to score marks here except for practice. Check out the video for profit and loss here:

Ratio and Proportion

Like Profit and Loss, this is an easy topic as well, but the main challenge students face here is reading and understanding the question correctly. In the examination, it is reasonable for anyone to get overconfident due to which they may not get the question correct or perhaps as they would be rushing, it is easy to make mistakes. However, should those be taken care of, then it’s quite possible to score marks well here. With regards to solving ratio and proportion questions, you shall find the video below helpful: 

Focusing on those topics is enough to help you score more than average marks and get you through the section with ease.

All the Best!
