The process of breaking down a long arithmetical calculation into simple parts and then solving it is known as simplification. Simplification questions for bank exams are one of the topics in the quant section of bank exams that requires an accurate and quick calculation to solve the maximum number of questions on it in less time.

Simplification questions for bank exams is a significant topic in Quantitative Aptitude for banking candidates because approximately 5-7 questions are asked from this topic alone, with up to 10 at the clerical level. Simplification questions for bank exams is a scoring section that can be aced with regular practice and a basic understanding of concepts and formulae to solve the numericals.

## What is Simplification?

Simplification questions for bank exams generally mean finding an answer for a complex calculation that may involve numbers on division, multiplication, square roots, cube roots, plus, and minus.

Simplification questions are asked in the Bank and Insurance exam to check the ability of an aspirant to deal with numbers which can be in one of the following two types.

• Sometimes, a calculation is given and one of the numbers is missing from the calculation. To find out the missing number, we have to approximate the given numbers or do the basic operations.
• Sometimes all the numbers are given with some operations between them & we have to simplify the calculation.

## Importance of Simplification Questions for Bank Exams

Simplification Questions for SBI PO is an important scoring section in Bank exams. Check out the important rules of simplification to perform well in the examination.

• 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, is 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 memorize 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).
• Simplification questions are an important component of the quantitative section.
• Helps candidates to score high marks.
• Problems are easy to solve using basic mathematics and can be grasped with regular practice.
• Knowledge of a few simplification tricks can help in quick solutions leading to better overall scores.

## Simplification Questions – Important Rules

Check out a few important rules to solve simplification questions for bank exams. Candidates must check out all the rules carefully as it is a step-by-step process and missing out on any step can lead to wrong answers.

Rule-(I) Replace ‘of’ by ‘Multiplication’ & ‘/’ by ‘Division’.

Explanation: Whenever we find ‘of’ in a simplification problem, we can replace that with ‘multiplication(*)’. Similarly ‘/’ can be replaced by ‘÷’.

Example: Find ¼ of 20

Solution: (¼) x 20 = 20÷4 = 5

Rule-(II)Always keep in mind the “BODMAS” rule. These operations have priorities in the same order as mentioned.

Explanation: Whenever we have more than one operation in the given calculation, we have to do the operations according to the priority specified by ‘BODMAS’

• B-Bracket
• O-Of (means multiplication)
• D-Division
• M-Multiplication
• S-Subtraction

Example: Simplify: (2+3)*30

Solution: In this question, we have two things-Bracket & Multiplication. According to the BODMAS rule, we have to solve the bracket first and not multiplication. So now coming to the bracket, we have only one operation-Addition, so we will do addition.

(2+3)*30 = 5*30

Now we have only one operation to do – Multiplication

5*30 = 150

Example: Simplify: (2+5) of 80

Solution: In this question, we have three things – bracket, addition & of. Replacing ‘of’ by ‘multiplication’.

(2+5) of 30 = (2+5)*80

Now we have three things – bracket, addition & Multiplication. According to the BODMAS rule, we have to solve brackets first and not multiplication. So now coming to the bracket, we have only one operation-Addition, we will do addition.

(2+5)*80 = 7*80

Now we will do multiplication.

7*80 = 560

Rule-(III) Multiplication & Division have the same priority(Do that operation first which is on the left)

Explanation: Though division has more priority than multiplication according to ‘BODMAS’, we can perform any two operations first if multiplication is on the left.

Example: 8*30/15

8*30 ÷ 15

Solution: In this question, we have two things – Multiplication & Division. Multiplication is on the left So we can perform that first.

Doing Multiplication first:

240 ÷ 15

16

Dividing first:

8*2

16

Rule-(IV) Addition & Subtraction have the same priority.

Explanation: Though addition has more priority than division according to ‘BODMAS’, we can perform any two operations first.

Example: 30+40-15

Solution: In this question, we have two things – Addition & Subtraction. So we can perform any operation first as they have the same priority.

70 – 15

55

Doing Subtraction first:

30 + 25

55

Rule-(V) Don’t hesitate in rounding the numbers to the nearest integers.

Explanation: Most of the time the numbers are given in such a way that you can round them quickly and get the answer (Rounding should be done or not, It can be realized by looking at the given options).

Example: (324.5*15)/(5.01*24.98)

Solution: (325*15)/(5*25)

=13*3

=39

610 -? = 310

? = 300 (Option 4)

Example 2: What will come in place of a: (128 ÷ 16 x a – 7*2)/(72-8*6+a2) = 1

1. 1
2. 5
3. 9
4. 13
5. 17

Solution: Using the BODMAS rule

(8*a – 14)/(49-48+a2) = 1

(8*a – 14)/(1 + a2) = 1

8a – 14 = 1 + a2

a2 – 8a + 15 = 0

a=3 or 5 (Option 2)

## Simplification Questions for IBPS Clerk

To solve simplification questions for IBPS Clerk one needs to use the BODMAS rule. Candidates must be conversant with all the rules to solve simplification questions for IBPS Clerk. Check out the below-mentioned examples to have a better understanding of this section.

Example 1:  (17 -13)4 – 174 – 134 – [- 52(17)3 – 68(133)] = (?)*221

Using formula: (a – b)4 = a4 – 4a3b + 6a2b2 – 4ab3+ b4)
⇒ (a – b)4 – a4 + 4a3b + 4ab3 – b4 = + 6a2b2
(17 -13)4 – 174 – 134 – [- 52(17)3 – 68(133)] = (?)*221
