Essential Short Tricks in Maths in CPT

Let’s dive into some of the most eﬀective and widely applicable short tricks that every

CPT candidate should know. These techniques cover various topics, from multiplication to

percentages, and are designed to simplify complex problems.

1. Multiplication Shortcuts

Multiplying large numbers can be intimidating, but there are clever ways to make the

process faster:

**Multiplying by 11:** To multiply any two-digit number by 11, add the digits and

place the sum between them.

For example, 23 × 11 = 2 (2+3) 3 = 253. If the sum exceeds 9, carry over the digit.

**Square of Numbers Ending with 5:** For any two-digit number ending in 5,

multiply the ﬁrst digit by its next higher digit and append 25.

Example: 35² = 3 × 4 = 12, so the answer is 1225.

**Multiplying Numbers Close to 100:** Subtract each number from 100, add the

diﬀerences, subtract from 100, and multiply the diﬀerences for the last two digits.

Example: 97 × 96

Diﬀerences: 3 and 4

Sum: 3 + 4 = 7

100 - 7 = 93

Multiply diﬀerences: 3 × 4 = 12

Result: 9312

These tricks not only save time but also help avoid errors in lengthy calculations.

2. Division Tricks

Dividing large numbers can be made simpler with some basic techniques:

**Divisibility Rules:** Quickly identify if a number is divisible by 2, 3, 5, 7, 11, or 13

using simple rules without actual division.

**Long Division Simpliﬁcation:** Use estimation and approximation to guess the

quotient's digits and adjust quickly rather than performing full division every time.

**Shortcut for Dividing by 5:** Multiply the number by 2 and move the decimal point

one place to the left.

For example, 125 ÷ 5 = (125 × 2) ÷ 10 = 250 ÷ 10 = 25.

3. Percentage Calculations Made Easy

Percentage problems often appear in CPT maths questions, and solving them fast is

crucial:

**10%, 5%, and 1% Calculations:** Calculate 10% by moving the decimal one place

left, 5% is half of 10%, and 1% is one-tenth of 10%.

**Finding Percent Increase/Decrease:** Use the formula [(New Value - Old Value) /

Old Value] × 100, but applying approximate values can speed up answers.

**Converting Percent to Fraction:** Remember common equivalents like 25% = 1/4,

50% = 1/2, which simpliﬁes calculations.

4. Square Root Estimation

Exact square roots may not always be needed. Estimating roots quickly can help in

multiple-choice questions:

Identify perfect squares near the number.

Use linear approximation between those squares.

For instance, to estimate √50, note that 49 and 64 are perfect squares. Since 50 is close

to 49, √50 ≈ 7.07.

5. LCM and HCF Shortcuts

Finding the Least Common Multiple (LCM) and Highest Common Factor (HCF) can be

tedious but is straightforward with prime factorization:

**Prime Factorization:** Break numbers into primes, multiply highest powers for

LCM, and multiply common primes for HCF.

**Relationship Between LCM and HCF:** Use the formula LCM × HCF = Product of

the two numbers, which often simpliﬁes calculations.

How to Incorporate Short Tricks in Maths in CPT Preparation

Learning these tricks is just the beginning; applying them eﬀectively requires practice and

strategy.

Practice Regularly

Short tricks lose their utility if you don’t practice them regularly. Set aside time every day

to solve problems using these techniques until they become second nature.

Identify Suitable Questions

Not all questions are suitable for shortcuts. Understand which problems can be solved

faster using tricks and which require traditional methods. This skill develops with

experience and mock tests.

Use Timed Mock Tests

Simulate exam conditions and time yourself. This approach helps you gauge how

eﬀectively you implement short tricks and manage time during the actual exam.

Maintain Accuracy

Speed is important, but accuracy is paramount. Always double-check critical steps,

especially in calculations involving carrying over numbers or decimals.
