In the Quantitative Aptitude section of the SBI Clerk Prelims exam, it is essential to prepare the following topics:

  • Simplification 
  • Approximation
  • Number Series
  • Data Interpretation

  • Miscellaneous questions (Profit Loss, Average, Simple & Compound Interest, Age, Ratio & Proportion, Time and Speed, etc.)

Let’s understand some important rules/ key things about the below-given topics. It will help you to prepare the topics in an efficient manner.

1. Simplification/ Approximation – Generally set of 5 questions come from this topic. In this, you have to find the value in place of the question mark.

Tips to solve this type of Questions in the exam –

(i) Basic Rules of Simplification – BODMAS Rule

Follow the correct sequence of operators to find the correct value in a given mathematical expression. This means that to simplify an expression, the following order must be followed –

B = Bracket, O = Order (Powers, Square Roots, etc.), D = Division, M = Multiplication, = Addition, S = Subtraction

(ii) These questions demand good calculation speed with a shortcut approach.

(iii) Learn tables up to 20, squares up to 30 and cubes up to 20 for faster calculation.

(iv) Don't waste time if you get stuck in any complex or large calculation. 

(v) Try to build good command on shortcut techniques for multiplication, cubes, squares, cube root, square root, etc. 

Approximation – In such questions, you have to find an approximate value which will come in place of the question mark in the questions. The first and foremost rule that you should apply here is the conversion of decimal numbers to the nearest number. This way you will simplify your equation and get an approximate answer.

2. Number Series – You can expect 5 questions from this topic too. In these questions, the series follows a logical rule based on elementary arithmetic. You can be asked to find the missing number in the sequence, the last number of the sequence or a new sequence based on the given pattern. For example:

a. 25, 49, 64, 100, 144, ? Find the last number of the sequence.

b. 1, 3, 8, 26, ?, 532   Find the missing number of the sequence.

c. 1, 8, 27, 64, 125

    a, b, c,  d, e. Find the value of e. 

On the basis of the pattern of the given sequence, you have to find the value.

Tips to solve the number series questions –

(i) Identify the pattern to solve a number series. Some of the basic patterns can be the difference between the numbers, the difference of differences, squares, cubes of numbers, multiplication, divisions, prime numbers. Practising such questions will help you to solve maximum questions.

(ii) Solve various math puzzles like sudoku. It will help you in building the logical path.

Important NoteLearning shortcut tricks like remembering squares, cubes and common fractions to decimals can be of great assistance in solving the questions. But, if there is a chance that error can occur or it is taking too much time, you may leave such questions and spend that precious time in solving other types of questions.
