How to Prepare:

  • Number series: this is the topic where one can expect 5 questions in prelims for sure . Even in mains 5 questions can be expected. The preparation methodology for this topic is be perfect with 
  • Prime Numbers upto-100 
  • Squares Upto-50 
  • Cubes Upto-20 
Because the logics or patterns among the numbers in the given series are framed with the above numbers in different permutations. Prepare a table like below and just memorize the numbers in vertical order so that one can identify the hidden logic easily.
Number(N) N2 N3 N2 +1 N2-1 N3-1 N3+1 Nn Nn +1 Nn/2 N3+N N3-N
0 0 1
1 1 2
2 4 9
3 3 28
4 16 65
5 25 126
6 36 217
7 49 344
8 64 513
9 81 730
10 100 1001
In this way memorize the vertical sequence so that whenever the difference between the numbers is drawn one can easily identify the logic.


Initially it was a scoring topic in quantitative aptitude but the level of difficulty in this topic is also increased . New variety of questions are being asked. For this one should look into the previous year questions and practice well.

This is one of the scoring topics , In this topic only limited models are asked so that one can master this topic easily. If asked in mains problems related to Cube root , square root are also asked .

Percentages + Averages+ Ratio-Proportions

How to attempt the Quantitative Aptitude Section:

  • Try to follow the order of answering as below – Simplifications - Quadratic Equation - Data Interpretation - Data Sufficiency - Single items
  • Focus on short cuts for basic mathematical operations like BODMAS.
