You can solve arithmetic problems in less than 60 seconds, but you have to apply smart speed math tricks, practice, and develop solid fundamentals. Rather than just using the conventional approaches based on a quantitative aptitude textbook or objective arithmetic textbook, learning the correct maths tricks to competitive exams can significantly cut down on the time taken to solve the problem and increase accuracy. Regardless of whether you are using the best book to prepare quantitative aptitude or any aptitude book, learning these tricks will be a significant boost in exams.
Why Speed Math is Important
Speed is a very important aspect in nearly all competitive exams. Arithmetic and quantitative aptitude sections are usually accompanied by time constraints, and it is necessary to find solutions as fast and as precise as possible. Applicants that depend on long calculations usually find it difficult to fill the paper.
Speed math saves time and increases confidence. You have more time to revise answers and do more questions when you can answer questions quicker. This is more so when you are practicing using a quantitative aptitude book or trying mock tests.
Basics You Must Know Before Learning Speed Tricks
It should be noted that before one leaps into tricks, a good foundation must be laid. Shortcuts may cause mistakes without the basic knowledge.
Strong Number Sense
You are supposed to be at ease with numbers, patterns and approximations. It is easier to use shortcuts when you understand the way numbers act. As an illustration, it would be easier to know that 49 is near to 50 or 98 is near to 100.
Tables, Squares, and Cubes
Learning multiplication tables to 20, squares to 30 and simple cubes can be very helpful in increasing speed. A majority of the issues in any aptitude book are simplified when you do not need to compute simple values over and over again.

Top Speed Math Tricks for Arithmetic
Speed math is about making things easier and not taking unnecessary steps. The following are some of the potent methods:
Fast Addition Tricks
Rather than adding numbers as we are used to, attempt to divide them into simpler components. For example, while adding 468 + 327, you can think of it as 468 + 300 + 27. This saves on mental burdens and accelerates calculations.
Left-to-right addition is another good technique that will allow you to come to the answer quicker without having to write down the steps
Quick Subtraction Techniques
With the complement method, subtraction is easier. To illustrate, you do not need to solve 1000 -487, but can reason how many you have to add to 487 to get 1000.
Another trick is rounding off numbers. For example, 502 – 298 can be calculated as 502 – 300 + 2, which is much faster.
Multiplication Shortcuts
The biggest time-saving tricks are used in multiplication.
The most common one is multiplying by 11. For example:
-
52 × 11 = 5 (5+2) 2 = 572
Near-base multiplication is another technique that can be helpful. For example:
-
98 × 97 can be solved by considering both numbers close to 100, reducing the complexity.
These methods are usually described in a good objective arithmetic book and are necessary to learn maths tricks in competitive exams.
Division Speed Tricks
Approximation can be used to simplify division. The answer is not solved, but estimated and improved. This is effective in multiple choice questions.
Calculation time is also minimized by breaking numbers into smaller parts or simplifying fractions.

Speed Tricks for Percentage, Ratio & Average
Shortcuts make the arithmetic topics such as percentages, ratios and averages a lot easier.
Percentage Tricks
It is easy to use percentages by transforming them into fractions. For example, 50% is 1/2, 25% is 1/4, and 10% is simply dividing by 10. The 10, 5 and 1 percent rule will enable you to compute nearly any percentage in your head.
Ratio & Proportion Tricks
It is time-saving to simplify ratios and then solve. To illustrate, do not work with large numbers, simplify them. Another fast way of solving proportion problems is by cross multiplication.
Average Shortcuts
Rather than summing up all the numbers, employ the supposed mean procedure. This saves on calculation effort particularly when numbers are near one another.

How to Solve Questions in Under 60 Seconds
Quickly solving needs a structured approach. The first step is to read the question and determine what kind of problem. Then, select the right trick rather than employing long procedures. Lastly, check your answer before it is too late.
Time management is also significant. When a question appears too long, then it is better to leave it and come back. This habit can be developed by practicing sets of questions with a book of quantitative aptitude on time.
Common Mistakes to Avoid in Speed Math
Speed math can be helpful, but when used excessively, it can create errors because of over-reliance on tricks without understanding. Most students hurry up with calculations and commit haphazard mistakes.
The other similar problem is neglecting simple concepts. No amount of the best book on quantitative aptitude can assist you when your fundamentals are weak. Speed and accuracy should be balanced.
Lastly, do not attempt new tricks in the exam. Always stick to what you have mastered.
Practice Plan to Improve Speed
Speed is something that must be practiced. It can be a big difference, and it does not take much time: 15-20 minutes a day. Pay attention to both simple and complex questions to gain confidence.
Regular solving of questions with a good aptitude book is also helpful to solidify the concepts and become faster with time.
