complete with solved examples, to help you crack numerical ability and reasoning

sections more efficiently.

Why Are Bank Exam Shortcuts Important?

Bank exams often include sections like quantitative aptitude, reasoning ability, and

general awareness, with a limited time frame. While a strong foundation in concepts is

essential, knowing shortcut methods can significantly reduce the time spent on lengthy

calculations or complex puzzles. Instead of spending minutes on a single question, these

shortcuts enable you to arrive at answers quickly without compromising accuracy.

Moreover, practicing these shortcuts regularly enhances mental agility and confidence,

making the exam experience less stressful. For many aspirants, these tricks are the

difference between clearing the cut-off and missing out by a few marks.

Popular Bank Exam Shortcuts with Example Solved

Let’s dive into some commonly used shortcuts across different topics, accompanied by

examples to clarify their application.

1. Simplifying Percentage Calculations

Calculating percentages quickly is crucial, especially in questions related to profit & loss,

discounts, and interest rates.

Shortcut: Convert percentages into fractions or decimals and use multiplication/division

tricks.

Example: Find 18% of 2500.

Traditional method:

18% of 2500 = (18/100) × 2500 = 0.18 × 2500 = 450.

Shortcut:

Think of 18% as 20% - 2%.

Calculate 20% of 2500 = (1/5) of 2500 = 500.

Calculate 2% of 2500 = (2/100) × 2500 = 50.

Now, 18% = 500 - 50 = 450.

This method avoids decimal multiplication and speeds up the process.

2. Speedy Calculation of Squares Ending with 5

Numbers ending with 5 have a unique pattern when squared.

Shortcut:

For any two-digit number ending with 5, say xy5, the square is given by multiplying x by

(x+1) and then appending 25.

Example: Calculate 75².

Multiply 7 by 8 (7+1): 7 × 8 = 56.

Append 25 to 56 → 5625.

So, 75² = 5625.

This trick works for any number ending with 5 (e.g., 35², 95²).

3. Divisibility Rules for Quick Checks

Knowing divisibility shortcuts can help eliminate options or verify answers instantly.

Divisible by 3: Sum of digits divisible by 3.

1.

Divisible by 4: Last two digits divisible by 4.

2.

Divisible by 11: Difference between sum of alternate digits is 0 or multiple of 11.

3.

Example: Is 7428 divisible by 3?

Sum of digits = 7 + 4 + 2 + 8 = 21, which is divisible by 3.

Therefore, 7428 is divisible by 3.

4. Average Shortcut Formula

Calculating average quickly is often tested in the quantitative section.

Shortcut:

Average = Total sum / Number of observations.

To find the average after adding or removing numbers, adjust the total sum accordingly.

Example: The average weight of 10 students is 50 kg. If one student weighing 60 kg

leaves, find the new average.

Total weight = 10 × 50 = 500 kg.

After removing 60 kg, total weight = 500 - 60 = 440 kg.

Number of students = 9.

New average = 440 / 9 ≈ 48.89 kg.

5. Time and Work Shortcut

Time and work problems are frequent in bank exams and can be tricky if approached

traditionally.

Shortcut: Use the formula:

Work done = (1 / Time taken)

If A can do a job in 'a' days and B in 'b' days, both working together can do it in:

(a × b) / (a + b) days.

Example: A can complete a task in 12 days, B in 16 days. How long will they take working

together?

Using the formula:

(12 × 16) / (12 + 16) = 192 / 28 ≈ 6.86 days.

Hence, together they finish in approximately 6.86 days.

Effective Tips to Use Bank Exam Shortcuts Efficiently

While shortcuts are handy, their effectiveness depends on how well you integrate them

into your preparation.

1. Understand the Concept First

Shortcuts are most useful when you have a solid grasp of the underlying concepts. Don’t

rely solely on tricks without understanding the basics.

2. Practice Regularly

Consistent practice of shortcut methods improves speed and reduces errors. Solve

previous years’ papers and mock tests using these shortcuts.

3. Identify Which Shortcut to Use

Different problems require different techniques. Train yourself to quickly identify the most

suitable shortcut for each question.

4. Avoid Blind Application

Sometimes, shortcuts might not be the best option, especially for complex problems. Use

discretion and avoid forced application.

Additional Bank Exam Shortcuts for Reasoning and Aptitude

1. Number Series Shortcuts

Often, the difference between consecutive numbers forms a pattern (arithmetic or

geometric). Quickly spotting this reduces time.

Example: Find the next number in the series: 2, 6, 12, 20, 30, ?

Differences: 4, 6, 8, 10 → increasing by 2.

Next difference = 12.

Next number = 30 + 12 = 42.

2. Simplifying Profit and Loss Calculations

Shortcut:

If the profit is x%, then

SP = CP + (x% of CP) = CP × (1 + x/100).

Similarly, for loss,

SP = CP × (1 - x/100).

Example: Cost Price (CP) = ₹500, Profit = 20%. Find Selling Price (SP).

SP = 500 × (1 + 20/100) = 500 × 1.20 = ₹600.

3. Using Approximation Techniques

When exact values are difficult, approximate numbers to closest convenient values for

quicker mental calculations.

For instance, to calculate 49.8 × 20.1, approximate as 50 × 20 = 1000 (close enough for

quick estimation).

Incorporating Bank Exam Shortcuts in Your Study Routine

Integrating shortcut methods into your daily study schedule can transform your

preparation. Start by learning a few shortcuts every week and practice them with example

questions. Over time, you will notice an improvement in your solving speed and

confidence.

Additionally, many coaching institutes and online platforms offer specialized sessions on

bank exam shortcuts and tricks. Leveraging these resources can provide structured

learning and exposure to diverse problem types.

It’s also helpful to maintain a “shortcut notebook” where you jot down new tricks along

with examples. This personalized reference can be invaluable during revision.

The journey to mastering bank exam shortcuts with example solved is a blend of

understanding, practice, and smart application. As you grow comfortable with these

techniques, you will find tackling the quantitative and reasoning sections not only faster

but also more enjoyable. This approach ultimately shifts your focus from mere calculation

to strategic problem-solving, a key skill in competitive exams.

important?

Bank exam shortcuts are quick calculation methods and

tricks used to solve numerical problems efficiently. They

are important because they save time during exams and

help improve accuracy in solving quantitative aptitude

questions.

Can you explain the shortcut

method for calculating the

square of a number ending

with 5 with an example?

To find the square of a number ending with 5, multiply

the first digit(s) by one more than itself and append 25

at the end. For example, 35²: Multiply 3 by 4 = 12, then

append 25, so 35² = 1225.

How can I quickly calculate 9

× a number using shortcuts

in bank exams?

To multiply a number by 9, multiply the number by 10

and then subtract the original number. For example, 9 ×

27 = (27 × 10) - 27 = 270 - 27 = 243.

What is the shortcut for

finding the percentage of a

given number with an

example?

To find x% of a number, multiply the number by x and

divide by 100. For example, to find 12% of 250: (12 ×

250) / 100 = 3000 / 100 = 30.

Explain the shortcut to solve

problems on profit and loss

with a simple example.

Profit or Loss % = (Profit or Loss / Cost Price) × 100. For

example, if cost price is 500 and selling price is 550,

Profit = 550 - 500 = 50. Profit % = (50/500) × 100 =

10%.

How to quickly find the LCM

of two numbers using the

shortcut method?

LCM of two numbers = (Product of the numbers) / (HCF

of the numbers). For example, for 12 and 15, HCF is 3, so

LCM = (12 × 15)/3 = 180/3 = 60.

What is the shortcut trick for

solving time and work

problems?

If A can do a work in 'a' days and B in 'b' days, then

together they can do it in (a × b) / (a + b) days. For

example, if A takes 4 days and B takes 6 days, together

they do it in (4 × 6)/(4 + 6) = 24/10 = 2.4 days.

How to quickly calculate the

compound interest using

shortcuts?

Compound Interest can be approximated using the

formula CI ≈ P × r × t / 100 when the rate and time are

small. For example, for P=1000, r=5%, t=2 years, CI ≈

1000 × 5 × 2 / 100 = 100. Exact CI can be found using

CI = P(1 + r/100)^t - P.

shortcuts. These techniques not only accelerate problem-solving but also reduce the

likelihood of errors caused by fatigue or time pressure.

Moreover, integrating shortcuts with consistent practice helps aspirants build confidence

and develop a systematic approach to tackling different question types. Understanding

when and how to apply these tricks is as important as memorizing them, ensuring that

candidates can adapt to varying question patterns.

Bank Exam Shortcuts with Example Solved: Key Techniques

1. Simplification and Approximation

Simplification shortcuts are particularly useful in questions involving large numbers or

complicated expressions. Instead of performing full calculations, candidates can

approximate values or use factorization to simplify expressions.

Example: Simplify (125 × 24) ÷ (25 × 12)

Step 1: Break down the numbers using factorization:

125 = 25 × 5

24 = 12 × 2

Step 2: Substitute these in the expression:

(25 × 5 × 12 × 2) ÷ (25 × 12)

Step 3: Cancel common factors (25 and 12):

= (5 × 2) = 10

This shortcut eliminates the need for lengthy multiplication and division, yielding a faster

and accurate result.

2. Percentage Shortcut

Percentage problems are common in banking exams, and several shortcuts exist to

calculate percentages quickly without using calculators.

Example: Find 8% of 250.

Step 1: Calculate 10% of 250 = 25

Step 2: 8% = 10% – 2%

Step 3: 2% of 250 = (2/10) × 25 = 5

Step 4: 8% of 250 = 25 – 5 = 20

This method avoids direct multiplication by converting percentages to simpler fractions

and subtracting or adding accordingly.

3. Speed Math Tricks for Multiplication

Multiplying numbers quickly is a critical skill, particularly for two-digit numbers close to 50

or 100. One such shortcut is the "Base Method" or "Complement Method."

Example: Multiply 97 × 96

Step 1: Identify the base as 100 (nearest power of 10)

Step 2: Calculate deficiencies from 100:

97 → 100 – 97 = 3

96 → 100 – 96 = 4

Step 3: Subtract crosswise:

97 – 4 = 93 or 96 – 3 = 93

Step 4: Multiply deficiencies:

3 × 4 = 12

Step 5: Combine the two parts:

Result = 9300 + 12 = 9312

This shortcut transforms the multiplication of two numbers into simple subtraction and

multiplication of smaller numbers, enhancing speed and accuracy.

4. Ratio and Proportion Shortcuts

In ratio problems, shortcuts can help solve equations faster by applying cross

multiplication or expressing variables directly.

Example: If the ratio of A to B is 3:4, and B is 20, find A.

Step 1: Write the ratio as A/B = 3/4

Step 2: Cross-multiply:

4A = 3 × 20

Step 3: Solve for A:

A = (3 × 20)/4 = 60/4 = 15

Using direct cross multiplication avoids setting up complex equations and saves time.

Applying Shortcuts Across Various Bank Exam Sections

Bank exams comprise multiple sections where shortcuts can be instrumental in

maximizing scores.

Quantitative Aptitude

The quantitative aptitude section benefits the most from shortcuts. Topics such as

simplification, percentages, profit & loss, time & work, and number series often have well-

known tricks that candidates can memorize and practice. For example, time and work

problems can be quickly solved using the concept of efficiency—calculating work done per

unit time and scaling accordingly.

Reasoning Ability

Reasoning questions require logical deduction and pattern recognition. Shortcuts in this

section often involve recognizing common logical sequences, eliminating options quickly,

or using diagrammatic methods such as Venn diagrams and puzzles like seating

arrangements.

English Language

Although shortcuts are less common in language sections, techniques such as skimming

and scanning can speed up reading comprehension. Likewise, mastering common

vocabulary and grammar rules reduces time spent on error detection or sentence

rearrangement questions.

General Awareness

General awareness demands updated knowledge and cannot be shortcut mathematically.

However, strategic preparation through focused reading and daily current affairs
