How to Prepare Maths for RRB NTPC 2019-20

To crack the RRB NTPC exam you need to work on the following parameters:

  • Beat the Clock 

    Time can be your worst enemy or a loving friend. Yes, you read it right. It solely depends on you how you treat this entity. Organizing yourself by devising a proper schedule and following it religiously can bring a drastic change in your life. Assign 2-3 hours daily to this subject and practice questions in a limited time followed by a thorough revision. 
  • Build your Concepts

    You can't just start with any topic blindly. Some topics form the basics for the other topics and so they need to be placed at the top of your preparation schedule. Start with the basics such as number system and you will be amazed to see its application on the other topics. Let us take a look at the topics which should form the start point of your journey.
  1. Number System
  2. Percentages
  3. Ratio & Proportion

Note: These three topics form the base of your preparation. So, practice them well. 

  • Bulk is better

    To clear your concepts on any topic, you need to practice problems in bulk. Take time to imbibe the concepts by practicing a lot of questions on it. There is no oral revision in maths, you need to practice questions in order to remember them for long. 
  • Break the Monotony

    When you start a topic, it is important that you go through all the variety of questions that appeared in various examinations. The more you expose yourself to diverse problems, the more you will feel at ease when an 'Out of the Box' problem hits you at the time of the exam.
  • 'Drop the Pen' Approach

    Minimize the use of pen as you get comfortable with various problems. In every competitive exam, there are at least 5-6 problems in every competitive exam that do not require the use of pen. Do not lose heart if you are not able to pick such problems at first as you will be able to do it gradually if your consistent in your preparation.

Important Tips to Follow

Now let us know the tips you need to follow to make your preparation effective.  

Follow one standard book religiously

There is an ample number of books available in the market but you need not go after each one of them. Instead, take a standard book that will clear your concepts and covers the entire syllabus. We are enlisting a few Important books to make your tasks easier

  1. Quantitative CAT by Sarvesh Kumar Verma
  2. Quantitative Aptitude for the CAT by Nishit K. Sinha
  3. Platform Series by Rukmini Publications

Start with one topic at a time and practice a variety of questions from the topic

Do not exert yourself too much by practising all the topics at once. Instead, go slow and start with one topic at a time and try to master the concepts behind it. If you come across any short method that will bring down the time factor, note it down immediately in your diary for future context.  

Do not underscore the power of formulas

Formulas do play an important role in any competition. They are devised for this purpose only i.e to cut down the time limit. Therefore, never hesitate to learn some important formulas. Without them, you may fall short in your defence. 

Work on your Speed

Speed can be a major hassle as you enter the competitive world. If you devote too much time on a question, you are more prone to lagging behind in the competition. However, if you stay consistent in your preparation, you are more likely to reach your goal faster. What should you do to increase your speed? Well, there are numerous ways to increase your speed like learning tables, squares, cubes, square roots, cube roots, etc. Inculcate all these things in your regime and feel the change. 

Maintain a diary of important questions & short notes

Maintaining a diary is one of the best ways to organize yourself. Doing this, you will avoid the hassle of reaching out to different sources that were once visited by you when you started off with your preparation. It is important to mention here that different problems can be solved using different approaches. Therefore, you are advised not to stick on one approach. If you find a short or an impressive approach, do not forget to mention that in your diary.

Analyze the Mock Tests

If you are not in a habit of analysing the mock tests, then develop one straight away. We have taken a problem from our 'Mock Test Series' which is designed by Maths experts. To every question, we have uploaded two types of approach:

1. Conservative Method (To help you understand the concept)

2. Short Approach (To help you save your time in the real exam)

A reduction of 21% in the price of Mangoes enables Ram to buy 7 kg more for Rs. 1000. Then find how many kgs of the mangoes will be bought at a reduced price if he will purchase mangoes for Rs. 1000?

Basic Method

Let the original price be ‘a’ per kg. 
Given, a reduction of 21% in the price of Mangoes enables Ram to buy 7 kg more for Rs. 1000. 
∴ Reduced price = a – 21% of a 
⇒ Reduced price = 0.79a 
Now, the number of kgs of mangoes bought at Rs. ‘a’ per kg for Rs. 1000 = 1000/a 
The number of kgs of mangoes bought at the reduced price of Rs. 0.79a per kg = 1000/0.79a 
⇒ 1000 – 790 = 7 × 0.79a 
⇒ 210 = 7 × 0.79a 
⇒ 0.79a = 30 
∴ Reduced price = Rs. 30 per kg 
He will purchase 1000/30 = byjusexamprep kg mangoes for Rs. 1000.

If you follow the basic approach to this problem, you will end up wasting your precious time. And if you follow the same approach for other problems as well, you will end up having no time for other sections. Therefore, it is advised that you expose yourself to different approaches and follow the one that helps you in getting the solution in no time. 

Short Method

In 21% (of the original price) at a reduced price, he buys 7 kg more
100%(of original price = 1000)=7*100/21=100/3kg

Practise Quizzes & Mock tests

The last step of every preparation is revision and practice. Some students devote their entire time in completing the entire syllabus and commit a mistake of not taking mock tests during this period. And after completing the syllabus, when they sit for the mock tests, they end up forgetting most of the topics. Quite Relatable, Right!!! Just Remember, Mock tests should be a part of your preparation and you should not wait for the syllabus to end in order to attempt quizzes or mock tests.

Go Through Previous Year Question Papers

This will help candidates to have an idea of the examination pattern. Aspirants should practice the previous papers at the time of revision so that they can know the time limit and can practice weak areas. Click to download RRB NTPC Previous Years' Papers PDF.
