Vedic Maths For Competitive Exams: Master Speed & Accuracy
In today’s fast-paced world of competitive exams, time is a crucial factor. Whether you’re preparing for banking exams, SSC, railways, Olympiads, or other entrance tests, your ability to calculate quickly can make a significant difference. Vedic Maths, an ancient Indian mathematical system, offers a set of techniques that help solve complex problems mentally and with incredible speed. Let’s explore how Vedic Maths can be a game-changer for competitive exam aspirants.
Why Vedic Maths for Competitive Exams?
- Boosts Speed & Accuracy: Vedic Maths techniques help in solving calculations faster than conventional methods, reducing errors significantly.
- Eliminates Dependence on Calculators: Competitive exams often do not allow calculators, making mental math skills essential.
- Simplifies Complex Calculations: Multiplication, division, squares, cubes, and even algebraic equations become easier and faster to solve.
- Saves Precious Time: Time management is key in exams; with Vedic Maths, you can solve problems in seconds, leaving more time for other questions.
Crack Banking & SSC Exams with these Vedic Maths Shortcuts
Banking, SSC, and government exams involve extensive numerical ability sections, where speed and accuracy are crucial.
Here are some Vedic Maths shortcuts that can help you ace these exams:
- Multiplication Trick – Base Multiplication
Suitable for numbers close to base values (10, 100, 1000, etc.).
Step-by-Step Explanation Using Nikhilam Sutra
The Nikhilam Navatashcaramam Dashatah Sutra translates to “All from 9 and last from 10.” This method is particularly useful when numbers are close to a base value (like 100, 1000, etc.)
Step 1: Identify the Base
- The nearest base to 103 and 105 is 100.
Step 2: Find the Deviations (Surplus or Excess)
- 103 is 3 more than 100 → (+3)
- 105 is 5 more than 100 → (+5)
Step 3: Cross-Addition and Multiply the Deviations
- The left part of the answer: 103 + 5 or 105 + 3 = 108
- The right part of the answer: (+3) × (+5) = 15
Step 4: Combine the Parts
- Final Answer = 108 | 15 → 10815
Thus, 103 × 105 = 10815 using the Nikhilam Sutra of Vedic Maths! 🚀
This method drastically simplifies multiplication when numbers are near a power of 10.
- Squaring Numbers Ending in 5
- Left is number on the left multiplied by the next number, right is 5 x 5 = 25
- Example: 35² = (3 × 4) | 25 = 1225.
- Addition & Subtraction Tricks
- Using number complements and rounding to simplify operations mentally.
- 266 + 98 = 266 + 100 = 366, 366 – 2 = 364
- 68 + 58 = 70 + 58 = 128, 128 – 2 = 126
- Percentage Calculation in Seconds
- Convert percentages into fractions for quick estimations.
- Example: 12.5% of 640 = 1/8 × 640 = 80
- Example: 25% of 320 = 1/4 × 320 = 80
Mental Math Techniques to Solve Problems Without a Calculator
Vedic Maths empowers you with mental strategies to tackle even the toughest problems without needing a calculator.
- Cross Multiplication for Fractions:
- Example: Solve 7/8 + 5/6 in seconds using cross-multiplication.
- Instant Subtraction Using All From 9 and Last From 10 [Nikhilam Sutra]
- The “All from 9 and the Last from 10” technique is a powerful Vedic Maths method used for quick subtraction, especially when subtracting from base values like 10, 100, 1000, etc.
How Does It Work?
Instead of using conventional borrowing, we apply a simple rule:
- Subtract each digit from 9 (except the last one).
- Subtract the last digit from 10.
Example 1: 1000 – 357
Let’s subtract 357 from 1000 using this method.
Step 1: Apply “All from 9 and Last from 10”
- Subtract 3 from 9 → 6
- Subtract 5 from 9 → 4
- Subtract 7 from 10 → 3
Thus, 1000 – 357 = 643 ✅
Let’s subtract 2689 from 10,000 using the same method.
Step 1: Apply “All from 9 and Last from 10”
- Subtract 2 from 9 → 7
- Subtract 6 from 9 → 3
- Subtract 8 from 9 → 1
- Subtract 9 from 10 → 1
Thus, 10,000 – 2689 = 7311 ✅
Why Use This Method?
✔ Faster than traditional borrowing
✔ Eliminates confusion and errors
✔ Works efficiently for large numbers
This trick is especially helpful in competitive exams where speed and accuracy matter.
- Magic Number for Divisibility:
- Learn quick checks for divisibility rules.
- Reverse Calculation for Checking Answers:
- Verify calculations instantly using inverse operations.
