1. Understanding Simplification Questions
Simplification refers to finding the correct value of a mathematical expression involving arithmetic operations such as addition, subtraction, multiplication, division, percentages, square roots, and exponents.
In IBPS exams, simplification questions are designed to test calculation speed and numerical accuracy. Candidates usually encounter 10–15 questions from this topic. Since the difficulty level is moderate, these questions provide an excellent opportunity to maximize scores.
For example:
48 ÷ 6 × 3 + 12
Using BODMAS:
48 ÷ 6 = 8
8 × 3 = 24
24 + 12 = 36
Answer = 36
Many students mistakenly solve operations from left to right without following the correct order. Understanding the structure of simplification questions is therefore essential.
Regular practice helps candidates identify patterns and avoid common mistakes. Since IBPS exams are highly competitive, solving simplification questions accurately within a few seconds can create a significant advantage over other candidates.
Aspirants should begin by strengthening basic arithmetic skills and gradually move towards advanced simplification problems involving fractions, roots, percentages, and powers.
2. Mastering the BODMAS Rule
BODMAS stands for:
B – Brackets
O – Orders (Powers and Roots)
D – Division
M – Multiplication
A – Addition
S – Subtraction
This rule determines the sequence of operations in simplification problems.
Example:
20 + (15 ÷ 3) × 4
Bracket first:
15 ÷ 3 = 5
Multiplication:
5 × 4 = 20
Addition:
20 + 20 = 40
Answer = 40
Many errors occur because students ignore the order of operations. Learning BODMAS thoroughly prevents unnecessary mistakes.
In IBPS exams, questions often include multiple operations in a single expression. Candidates must quickly identify which operation to perform first.
Practice questions involving nested brackets, powers, roots, and fractions. With repeated exposure, the application of BODMAS becomes automatic.
A strong command of BODMAS is the foundation of simplification and directly improves accuracy and speed in examinations.
3. Importance of Fast Calculation Skills
Fast calculations play a major role in simplification. Candidates who perform arithmetic quickly can save valuable time for difficult questions.
Important calculations to memorize:
Squares up to 50
Cubes up to 30
Fraction-to-percentage conversions
Tables up to 25
Example:
25² = 625
35² = 1225
45² = 2025
Similarly:
12.5% = 1/8
20% = 1/5
25% = 1/4
Rapid recall eliminates the need for lengthy calculations during the exam.
Daily practice of mental arithmetic improves numerical agility and confidence. Candidates should spend 15–20 minutes every day practicing multiplication, division, squares, and percentage calculations.
Using calculation shortcuts reduces dependence on rough work and enhances speed significantly.
4. Approximation Techniques
Approximation helps solve lengthy calculations quickly.
Example:
498 × 21
Approximate:
500 × 20 = 10000
Actual answer will be close to 10000.
Approximation is particularly useful when answer choices are widely separated.
Common approximation rules:
498 ≈ 500
199 ≈ 200
9.98 ≈ 10
4.99 ≈ 5
Candidates should use approximation only when answer options allow it. If options are very close, exact calculation becomes necessary.
Approximation saves time and is one of the most important techniques used by toppers in banking examinations.
5. Solving Questions with Fractions
Fractions frequently appear in simplification problems.
Important Fraction Values:
1/2 = 50%
1/3 = 33.33%
1/4 = 25%
1/5 = 20%
1/8 = 12.5%
Example:
(3/4 × 200) + (1/5 × 100)
= 150 + 20
= 170
Understanding fraction conversions simplifies calculations dramatically.
Practice converting percentages into fractions and vice versa. This technique helps solve questions involving ratios, percentages, and simplification much faster.
6. Square Roots and Cube Roots Tricks
Questions involving roots are common in IBPS exams.
Example:
√144 = 12
√225 = 15
∛125 = 5
∛216 = 6
Memorizing perfect squares and cubes enables instant solutions.
Candidates should learn:
Squares up to 50
Cubes up to 30
Square roots of common perfect squares
Cube roots of common perfect cubes
Strong knowledge of roots reduces calculation time and improves accuracy.
7. Percentage-Based Simplification
Percentages are often combined with arithmetic operations.
Example:
25% of 400 + 20% of 250
= 100 + 50
= 150
Useful conversions:
50% = 1/2
25% = 1/4
75% = 3/4
12.5% = 1/8
Converting percentages into fractions makes calculations easier and faster.
Candidates should regularly practice percentage calculations because they appear in multiple aptitude topics.
8. Common Mistakes to Avoid
Frequent mistakes include:
Ignoring BODMAS
Incorrect decimal calculations
Wrong percentage conversions
Calculation errors
Rushing through questions
Example:
16 ÷ 4 × 2
Correct:
16 ÷ 4 = 4
4 × 2 = 8
Many students mistakenly write:
16 ÷ 8 = 2
Avoiding such mistakes can improve scores significantly.
Accuracy should always accompany speed.
9. Time Management Strategies
Simplification questions should ideally be solved within 20–30 seconds.
Tips:
Attempt simplification first.
Skip lengthy calculations initially.
Use approximation wherever possible.
Avoid spending more than 40 seconds on a single question.
Regular timed practice develops examination temperament and improves overall performance.
Candidates should solve mock tests regularly to identify weak areas and improve speed.
10. Practice Examples for IBPS Exams
Example 1:
45 + 15 × 2
= 45 + 30
= 75
Example 2:
225 ÷ 15 + 10
= 15 + 10
= 25
Example 3:
√324 + 16
= 18 + 16
= 34
Example 4:
25% of 800
= 200
Example 5:
(3/5 × 250) + 50
= 150 + 50
= 200
Practicing similar questions daily builds confidence and enhances calculation speed.
The more questions you solve, the better your accuracy and speed become.
