How to Approach Simplification questions?

1. BODMAS Rule

The first thing to keep in mind while solving simplification/approximation questions is the proper application of ‘BODMAS’ rule.

‘BODMAS’ is an acronym that is used to denote the order of operations to be followed while calculating the simplified value of a given expression.
It stands for
B – Brackets
O – Order of power or roots (it also stands for the expression “of”)
D – Division
M – Multiplication
A – Addition
S – Subtraction

Mathematical expressions having multiple operations need to be solved from left to right using this order only i.e. BODMAS

Important Question Simplification For IBPS RRB 2024 Exam

Question 1: What will come in the place of question mark (?) in the given expression?

[{(4608 ÷ 24) ÷ 12} ÷ 4] + 11²+ √169 = ?

A) 133

B) 138

C) 143

D) 148

E) None of these

Ans: 2

Solution:

[{(4608 ÷ 24) ÷ 12} ÷ 4] + 11²+ √169 = ?

? = [{192 ÷ 12} ÷ 4] + 121+ 13

? = [16 ÷ 4] + 134

? = 4 + 134

? = 138

Hence, option b.

Question 2: What will come in the place of question mark (?) in the given expression?

125 + ? + 272 – 391 = 184 – 215 + 169

A) 124

B) 128

C) 132

D) 136

E) None of these

Ans: 3

Solution:

125 + ? + 272 – 391 = 184 – 215 + 169

? + 397 – 391 = 353 – 215

? + 6= 138

?= 138 – 6

? = 132

Hence, option c.

Question 3: What will come in the place of question mark (?) in the given expression?

256⁴ ÷ 64⁶ × 16² = 4^?

A) 4

B) 8

C) 2

D) 6

E) None of these

Ans: 3

Solution:

256⁴ ÷ 64⁶ × 16² = 4^?

4^?= (4⁴)⁴ ÷ (4³)⁶ × (4²)²

4^?= 4¹⁶ ÷ 4¹⁸ × 4⁴

4^?= 4^16-18+4

4^?= 4²

? = 2

Hence, option c.

Question 4: What will come in the place of question mark (?) in the given expression?

√225 + √729 – √324 = 20% of ?

A) 120

B) 124

C) 128

D) 132

E) None of these

Ans: 1

Solution:

√225 + √729 – √324 = 20% of ?

0.2 × ? = 15 + 27 – 18

0.2 × ? = 24

? = 24/0.2

? = 120

Hence, option a.

Question 5: What will come in the place of question mark (?) in the given expression?

30% of 150 = 15% of ? + 20% of 180

A) 45

B) 60

C) 75

D) 90

E) 105

Ans: 2

Solution:

30% of 150 = 15% of ? + 20% of 180

0.15 × ? + 0.20 × 180 = 0.30 × 150

0.15 × ? + 36 = 45

0.15 × ? = 9

? = 9/0.15

? = 60

Hence, option b.

Question 6: What will come in the place of question mark (?) in the given expression?

√2116 × 4 + ?³ = 696

A) 8

B) 9

C) 7

D) 6

E) None of these

Ans: 1

Solution:

√2116 × 4 + ?³ = 696

46 × 4 + ?³= 696

184 + ?³ = 696

?³ = 512

? = 8

Hence, option a.

Question 7: What will come in the place of question mark (?) in the given expression?

12.5% of 4960 + ?% of 2400 = 1580

A) 25

B) 40

C) 50

D) 45

E) None of these

Ans: 2

Solution:

12.5% of 4960 + ?% of 2400 = 1580

620 + ? × 24 = 1580

? × 24 = 960

? = 960/24 = 40

Hence, option b.

Question 8: What will come in the place of question mark (?) in the given expression?

4225% of 40 + 1226 = ?²

A) 56

B) 60

C) 62

D) 58

E) None of these

Ans: 5

Solution:

4225% of 40 + 1226 = ?²

0.4 × 4225 + 1226 = ?²

1690 + 1226 = ?²

?²= 2916

? = 54

Hence, option e.

Question 9: What will come in the place of question mark (?) in the given expression?

?% of 600 – 120 = 8² + 4²

A) 40

B) 100/3

C) 50

D) 200/3

E) 25

Ans: 2

Solution:

?% of 600 – 120 = 8² + 4²

? × 6 – 120 = 64 + 16

? × 6 = 200

? = 200/6 = 100/3

Hence, option b.

Question 10: What will come in the place of question mark (?) in the given expression?

{(452 – 214 + 72) / 5} × 2 = ?

A) 154

B) 142

C) 124

D) 136

E) None of these

Ans: 3

Solution:

{(452 – 214 + 72) / 5} × 2 = ?

? = (310 / 5) × 2

? = 62 × 2

? = 124

Hence, option c.
