The process of breaking down a long arithmetical calculation into simple parts and then solving it is known as a simplification. An approximation is a process of rounding off for simplicity in a calculation (like 2.003, taken as 2). Both are an important component of the quantitative section of bank exams. Questions on simplification and approximation for bank exams help candidates to score good marks and therefore, many of them use simplification and approximation pdf download of previous bank exam questions as an important study material. You can easily get simplification and approximation previous years’ questions from BYJU'S Exam Prep.

Important Simplification and Approximation Topics



The BODMAS rule

The order of operation for solving an expression is,

1)  Simplify the term inside the Bracket. 2) The second process involves working on the exponents and roots. (Of)  3) Next is the Division. 4) Then, Multiplication. 5) The addition is next. 6) The last one, Subtractions.

 Solving a given problem in the wrong order will give you the wrong answer. 

Polynomial Equation (An equation made up of numbers & variables)

 Formulas for solving such equations like, (a+b)2, (a3+b3) are to be remembered.

Ratio & Proportion

Basic school level concepts

Time and Distance

Remembering basic formula ,d= rt

Unitary method

Finding the value of a unit first from the value of a multiple.


Geometric method of measurement

Basic Geometry

Basic  school level concepts

Tips to Solve Simplification and Approximation Questions:

A) Remember the rules related to simplification:

  • Replace of by multiplication and, / by division.
  • BODMAS - operations in the correct priorities.
  • Both Division and Multiplication have the same priority. The operation which is appearing on the left, to be attempted first.
  • Same priority for Additions and Subtractions.
  • Decimals may be rounded off the nearest integer (164.6 to be taken as 165)
  • Try to  memorise squares (1 to 30  at least) and cubes(1 to 15) of numbers
  • Remember common fraction values (like, 5% is 0.05 , 10% is 0.1 and 100% is 1 , 250% is 2.5 etc)
  • Have a clear concept of Reciprocals ( a number divided by 1) and for a fraction, it is reversing the numerator/denominator (1/6 becomes 6/1).

B) Other Tips

  • Study the question carefully and understand the total logic before you start solving so that you work with only one logic/option.
  • Practise with the time tested method of mock tests and solving previous years’ papers.

Importance of Simplification in the Quantitative Section of Competitive Banking & Government Exams
