  # Simplification and Approximation for Bank and Insurance Exams like: SBI PO, IBPS PO, IBPS RRB PO, SBI Clerk, IBPS Clerk, NIACL, LIC Etc

Dear Aspirants, Simplification is one of the most important topic for all bank and insurance exams you can easily gain 4 to 5 marks in 3 just to 5 minutes, so in this article we will discuss types of simplification question is being asked in SBI PO, IBPS PO, IBPS RRB PO, NIACL, LIC, IBPS Clerk, SBI Clerk and other Bank & Insurance Exams. Approximation is also a part of simplification which will discuss further in brief.

In simplification questions, a normal student/aspirant would be roughly calculation for approximately 50% of the time that he/she takes to solve a question. This means that half the total time that you would spend in solving questions of basic simplification would essentially go into calculations. Thus, if the test paper consists of say 30-40% questions on basic numeracy and data interpretation you would be expected to spend somewhere between 16 to 28 minutes on these questions – which would in turn translate to approximately 18 to 24 minutes in calculations inside the test paper.

So the contention is this: If you can improve your calculation speed to 3x, the time you would require to do the same calculations would come down to 1/3th of your original time. In other words, 18 minutes would come down to 7.3 minutes – a saving of 14.6 minutes just by improving your calculation speed!!

In exams like the Bank and Insurance where you would always run out of time 14 extra minutes could easily means between 10–12 marks.

10–12 extra marks in the prelims exam could very well make the difference between getting a chance to write the mains examination in the same year versus going back to the drawing board and preparing for the prelims for another year!!

In this article, we will discuss that one has to follow while solving simplification and approximation questions.

Introduction: To solve such arithmetical questions, aspirant has to solve Vinculum Bar (-), addition (+), subtraction (–), multiplication (×), division (÷), root (√), and brackets, etc systematically. Let discuss VBODMAS rule to make this intro clearer.

VBODMAS rule gives the correct order in which various operations regarding simplification are to be performed, so as to find out the values of given expressions in simple ways. Let us see what these letters mean.

V = Vinculum Bar
B = Brackets,
Order of removing brackets
I: Vinculum Brackets (Bar Brackets) ‘–’
II:  Small Brackets (Circular Brackets) ‘( )’
III:  Middle Brackets (Curly Brackets) ‘{ }’
IV: Square Brackets (Big Brackets) ‘[ ]’
O = Of
D = Division (÷)
M = Multiplication (×)
S = Subtraction (–)

Order of above mentioned operations is as same as the order of letters in the ‘VBODMAS’ from the left to right as

V → B → O → D → M → A → S
Left to Right
Clearly, the order will be as follows:
First Vinculum bracket is solved,
Remember[– 5 – 10 = – 15 but –5 – 10 = –(–5 ) = 5],
Secondbrackets are to be solved in order given above,
[First, then second, then third and then fourth]
Third Operation of ‘Of’ is done,
Fourth Operation of division is done,
Fifth Operation of multiplication is done,
Sixth Operation of addition is done, and

Seventh Operation of subtraction is done

So, aspirants need to solve a given expression at simpler or equivalent one. Here are different types of Simplification questions in the form of quizzes and PDFs which have been seen in different bank and Insurance Exams, you can take quizzes online and check your level of preparedness for SBI PO 2019, IBPS PO 2019, SBI Clerk 2019, IBPS Clerk 2019, IBPS RRB PO and even download simplification PDFs so you can solve them offline too.
