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).

- Knowledge of a few simplification tricks can help in quick solutions leading to better overall scores.
Important Topics For Simplification
Check out the important topics for simplification questions for SBI Clerk with maximum weightage. These topics will help candidates understand difficult concepts in a better manner.
TOPIC | DETAILS |
The BODMAS rule | The order of operation for solving an expression is, Simplify the term inside the Bracket. The second process involves working on the exponents and roots. (Of) Next is the Division. Then, Multiplication. The addition is next. 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 the basic formula,d= rt |

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
- A-Addition
- 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.
Doing Addition first:
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

Simplification Questions for SBI PO
Candidates can check out samples of simplification questions for SBI PO here. Simplification is an important section of the SBI PO exam. Candidates must follow the important steps and practice frequently to clear all the difficult concepts. Sample papers will be really helpful for candidates to practice simplification questions for SBI PO and ace their exams meritoriously.
Example 1: What will come at place of ?: 85.147 + 34.192*6.2 +? = 802.293
- 400
- 450
- 550
- 600
- 500
Solution: Using the rounding concept
85 + 35*6 +? = 803
Using the BODMAS rule
85 + 210 + ? = 803
295 + ? = 803
? = 508 [approx. = 500] (Option 5)
Example 2: What will come at place of? : (3/8 of 168)*15 ÷ 5 + ? = 549 ÷ 9 + 235
- 189
- 107
- 174
- 296
- None of these
Solution: Using the BODMAS rule
(3*168÷8)*15 ÷ 5 +? = 549 ÷ 9 + 235
(504÷8)*3 + ? = 61 + 235
63*3 + ? = 296
189 + ? = 296
? = 107 (Option 2)
Simplification Questions for SBI Clerk
The SBI Clerk exam comprises two stages - prelims and mains and in both phases, simplification is one of the most essential sections. To solve simplification questions for SBI Clerk candidates must practice the previous year's questions and mock tests to gain confidence and avoid exam jitters in the examination hall. Check out a few model questions with detailed solutions for simplification questions for SBI Clerk here-
Example 1: What will come at the place of ?: 9876 ÷ 24.96 + 215.005 -? = 309.99
- 270
- 280
- 290
- 300
- 310
Solution: Using the rounding concept
9875 ÷ 25 + 215 -? = 310
Using the BODMAS rule
395 + 215 - ? = 310
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
- 5
- 9
- 13
- 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
Here, a = 17 and b = 13
⇒ (?)= (6 (17)2 (13)2)/221
⇒(?) = (6 × 289 × 169)/221
⇒ (?) = 1326
Example 2: Simplify: 127.001 * 7.998 + 6.05 * 4.001
- 1000
- 1020
- 1040
- 1080
- None of these
Solution: Using the rounding concept
127 * 8 + 6 * 4
Using the BODMAS rule
1016 + 24
1040 (Option 3)
