Speed Maths Tricks for Banking Exams: Fast Calculation Shortcuts

Speed Maths Tricks for Banking Exams help candidates perform calculations faster and save valuable time in the Quantitative Aptitude section. These techniques focus on mental calculation, Vedic Maths shortcuts, fraction-to-percentage conversions, multiplication and division tricks, squares and cubes, simplification, and approximation. Since banking exams require candidates to solve Quant questions under strict time limits, reducing calculation time while maintaining accuracy can help improve overall time management. This guide covers practical speed maths tricks for IBPS, SBI, RRB, and other banking exams, along with methods to build faster calculation skills through regular timed practice.

What Are Speed Maths Tricks for Banking Exams?

Speed maths tricks for banking exams are shortcut calculation methods that reduce the number of steps required to solve Quantitative Aptitude questions. They are particularly useful in Simplification, Approximation, Number Series, Data Interpretation and arithmetic-based questions.

For example, instead of calculating 48 × 25 through conventional multiplication, you can use:

48 × 25 = 48 × 100 ÷ 4 = 1200

The objective is not simply to memorise formulas. Candidates should understand when a shortcut is useful and practise it until the method becomes automatic.

Why Is Speed Maths Important in Banking Exams?

Banking examinations use sectional or time-bound Quantitative Aptitude tests, depending on the examination. For example, SBI’s official PO information lists 35 Quantitative Aptitude questions in the preliminary examination, while its current Junior Associate information lists 35 Quantitative Aptitude questions in Prelims. 

Therefore, spending too much time on basic calculations can reduce the number of questions you can attempt. Speed maths helps you:

• Reduce calculation time
• Improve accuracy
• Avoid unnecessary written steps
• Solve DI calculations faster
• Handle Simplification and Approximation efficiently
• Improve overall time management

Important Speed Maths Topics for Bank Exams

The following speed maths topics for bank exams should be included in your preparation because they form the foundation for faster calculations.

10 Speed Maths Tricks for Banking Exams

These speed maths tricks for banking exams focus on calculations that repeatedly appear in banking Quant sections. Practise each technique with different numbers instead of memorising only the examples.

1. Memorise Important Tables

Tables are the foundation of fast calculation. Start with tables up to 20 and gradually extend them to 25 or 30.

For example:

17 × 8 = 136
24 × 7 = 168
28 × 9 = 252

Quick recall saves time during multiplication, division and DI calculations.

2. Learn Common Fraction-to-Percentage Conversions

Memorising frequently used fractions can eliminate lengthy calculations.

For example, 12.5% of 800 = 800 ÷ 8 = 100.

3. Square Numbers Ending in 5

For a number ending in 5, multiply the number before 5 by its successor and append 25.

75²

7 × 8 = 56

Therefore:

75² = 5625

Similarly:

85² = 8 × 9 | 25 = 7225

This is one of the easiest calculation shortcuts to practise.

4. Multiply a Number by 11

For a two-digit number, add the two digits and place the result between them.

43 × 11

4 + 3 = 7

Therefore:

43 × 11 = 473

For 78 × 11:

7 + 8 = 15

After carrying:

78 × 11 = 858

5. Multiply by 25 Quickly

Since:

25 = 100 ÷ 4

you can divide the number by 4 and multiply by 100.

For example:

48 × 25 = 48 ÷ 4 × 100 = 1200

Another example:

64 × 25 = 16 × 100 = 1600

6. Divide by 5

To divide a number by 5, multiply it by 2 and divide by 10.

240 ÷ 5

= 240 × 2 ÷ 10

= 48

This method is particularly useful when the number is even.

7. Divide by 25

Use:

25 = 100 ÷ 4

Therefore:

600 ÷ 25 = 600 × 4 ÷ 100 = 24

Similarly:

800 ÷ 25 = 32

8. Use the Percentage Interchange Trick

A useful percentage shortcut is:

A% of B = B% of A

For example:

64% of 25

can be changed to:

25% of 64 = 64 ÷ 4 = 16

Therefore:

64% of 25 = 16

This trick is especially useful in DI and percentage-based arithmetic.

9. Use Base Method for Numbers Near 100

When two numbers are close to 100, the base method can make multiplication faster.

For example:

97 × 103

= (100 – 3)(100 + 3)

Using:

(a – b)(a + b) = a² – b²

we get:

= 100² – 3²

= 10000 – 9

= 9991

10. Use Approximation When Appropriate

Approximation can save considerable time when the question asks for an approximate value or when the answer options are sufficiently far apart.

For example:

398 × 51

can be approximated as:

400 × 50 = 20,000

However, approximation should only be used when the question and answer options allow it. Do not sacrifice accuracy simply to save a few seconds.

Speed Maths Tricks for Percentage Calculations

Percentage calculations appear across Data Interpretation, Profit & Loss, Simple Interest, Compound Interest and other arithmetic topics. Therefore, percentage shortcuts should be a priority in speed maths practice for bank exams.

Common Percentage Values

For example:

37.5% of 800

= 3/8 × 800

= 300

Successive Percentage Change

For two successive percentage changes of a% and b%, the net percentage change is:

a + b + (ab/100)

Use the appropriate sign for increase or decrease.

For example, a 20% increase followed by a 10% increase gives:

20 + 10 + (20 × 10)/100

= 32% increase

How to Use Speed Maths in Data Interpretation

Speed maths is especially useful for Data Interpretation, where calculations can consume more time than understanding the graph or table.

Before calculating, check whether the question can be solved through:

• Percentage comparison
• Ratio comparison
• Approximation
• Fraction conversion
• Difference calculation
• Average shortcut
• Option elimination

For example, if a DI question asks you to calculate 12.5% of 640, do not perform a lengthy percentage calculation.

Simply use:

12.5% = 1/8

Therefore:

640 ÷ 8 = 80

This approach can save several seconds across a complete DI set.

How to Practise Speed Maths for Bank Exams

Learning shortcuts is only the first step. Regular speed maths practice for bank exams is required to make these methods automatic.

Follow this simple daily routine:

Start without a timer while learning a new trick. Once you understand the method, introduce a time limit and gradually increase the difficulty.

Speed vs Accuracy: What Should You Prioritise?

Do not try to become fast by rushing through every question. Accuracy should come first, followed by speed.

A useful progression is:

Understand the concept > Learn the shortcut > Practise slowly > Practise with a timer > Apply in mocks

This prevents candidates from developing fast but inaccurate calculation habits.

Common Mistakes to Avoid While Using Speed Maths Tricks

Even the best fast maths tricks for banking can reduce your score if used incorrectly. Avoid these common mistakes:

• Memorising shortcuts without understanding them
• Using approximation when exact calculation is required
• Applying a shortcut to an unsuitable question
• Ignoring basic arithmetic
• Focusing only on speed and neglecting accuracy
• Learning too many tricks without practising them
• Not revising tables, squares and fractions regularly

A shortcut should reduce calculation steps, not increase the possibility of an error.

How to Improve Calculation Speed for Banking Exams

To improve calculation speed consistently:

1. Memorise essential tables, squares and cubes.
2. Revise common fraction-percentage conversions.
3. Practise multiplication and division shortcuts daily.
4. Solve 10–20 timed calculation questions.
5. Apply shortcuts to DI and arithmetic questions.
6. Analyse calculation errors after every practice session.
7. Use sectional tests and full-length mocks to measure improvement.

Candidates preparing for different banking examinations should adapt their practice according to the latest official exam pattern and notification because the structure and timings can vary between examinations. SBI’s official information, for instance, shows different Quantitative Aptitude structures across its PO and Junior Associate examinations. 

Conclusion

Speed maths tricks for banking exams are most effective when they become part of your regular Quantitative Aptitude practice rather than something you memorise just before the examination. Start with basic calculations, fractions, percentages, multiplication and division before moving to advanced shortcuts.

With consistent speed maths practice for bank exams, you can gradually improve both calculation speed and accuracy. Practise these techniques through timed quizzes and mocks on PracticeMock to understand which areas need more improvement.
