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.
