If you’re a competitive exam aspirant, you’re already aware of the importance of quantitative aptitude. While some questions might be time-consuming, you’ll be surprised to know that you can even solve them in under 30 seconds. Want to know how? Let us show you how:
1. Use Vedic Math for Fast Calculations
Vedic Math tricks help in simplifying complex calculations. Whether it’s multiplication, division, or squaring numbers, these ancient techniques can save you enough time. Many modern Quantitative Aptitude Books now include a dedicated section on these methods.
Let’s understand this with an example. If you need to multiply 97 × 96, all you’ve got to do is use the following formula:
(Base – Difference)² + Cross Subtraction = 9312 (in seconds!)
2. Try Approximation
In exams, you can solve faster by rounding off numbers when the options are close. You don’t need to aim for exact figures every time. Rather, you must learn to judge when it’s safe to use an approximation and go ahead with your calculation. This trick is particularly helpful in questions that involve ratios, averages, and percentages.
3. Break Down Large Numbers
Instead of multiplying large numbers straight, break them into smaller factors.
Example:
125 × 48 = (125 × 50) – (125 × 2) = 6250 – 250 = 6000
Such breakdowns are usually used in the quantitative aptitude for competitive examination formats.
4. Learn Percent to Fraction Conversion
You must memorise some basic percent to fraction conversions like the following:
-
25% = 1/4
-
12.5% = 1/8
-
33.33% = 1/3
This helps you increase your speed in questions related to profit & loss, discount, and interest.
5. Master Shortcut Formulas
There are several formula-based shortcuts for time, speed, distance, work, etc. The best book for quantitative aptitude will provide these, along with examples. You can use them rather than trial and error!

6. Option Elimination
Sometimes you don’t need to solve the entire problem. You just need to check which option is logically correct. This technique works well in number systems and algebra. You can learn smart back-solving techniques from any authentic quantitative aptitude book.
7. Time-Bound Practice
You must practice regularly to apply the shortcuts accurately. Solve at least 10 questions by setting a timer. Try reducing your time per set gradually. You can find time-based tests in quantitative aptitude for competitive examinations books, offering level-wise difficulty that mirrors actual exams.
Final Thoughts
Speed matters, but only when combined with accuracy. These tricks boost both. To master them, pick a reliable quantitative aptitude book that explains concepts and includes shortcut methods, previous year questions, and mock tests. If you're still searching for a suitable resource, choose one that’s exam-specific, practice-rich, and trick-loaded, because in competitive exams, every second saved is a mark earned.
