Overview: When appearing for competitive exams with quantitative aptitude as one of the main subjects the main concern should be solving questions in the shortest possible time. Knowing multiplication and division given in this article helps you with the same.
If you are an aspirant for the IPMAT exam but worried about performing calculations in less time, this article will equip you with the shortcuts to do just that.
Learn the different techniques for solving multiplication and division tricks for competitive exams. Solve solve IPMAT multiplication and division questions faster by multiplication short tricks to save your time and attempt all the questions.
The majority topics from Quantitative section of IPMAT require the basic multiplication, and division. Mastering the shortcuts of multiplication, and division for IPMAT will give you extra time for other questions.
Mainly, the topics including Number System, Averages & Percentages, Roots, Indices, Surds, Simple & Compound Interest, Profit & Loss, Algebraic Formulae, Linear & Quadratic Equations, Ratio & Proportion, Partnership, Mixtures & Alligations, Time, Speed & Distance, Work Related Problems, and Pipes & Cisterns require faster calculation technique of multiply and divide.
Learning simple tricks will help manage your time in the final exam and help you solve the questions with utmost accuracy. You can learn tips and tricks to improve your efficiency and accuracy within the stipulated time by learning simple tricks to attempt questions in the IPMAT Quant section.
Note: The quantitative tricks differ in length depending on the mathematical operation and the numbers involved. If you can calculate the problems in seconds by using short tricks, scoring the marks in the exam is easy.
Without knowing the trick, many of you might waste your time multiplying a particular number with 5.
Generally, 5 is expressed as, 10/2.
Whenever you convert 5 from 10/2, the calculation becomes easy.
For Example:
If you want to multiply 72 X 5. Replace 5 by 10/2
Then, it will become 72 X 10/2
Divide the 72/2 , which is 36
Finally, multiply 36 with 10, (36X10). The final answer is 360
Knowing the short trick to multiply any number by 11 will help you solve the problem in less than 5 seconds.
Suppose if you want to multiply PX11
For Example:
Multiply 58X11 by using the trick mentioned above.
The last digit of the answer is the last digit of P. Here, P is 58, which means 8 is the last digit.
The middle digit of the answer is the last digit of the sum of all numbers of P: 5+8=13 i.e., 3
The first digit of the answer is the first digit of P plus they carry (if any): 5+1=6
Hence, the final answer for 58X11 is 638
Add AB0 + CDE = your answer
For example:
Consider multiplying 56 by 15 using the simple technique explained below:
Add a zero to the first number i.e., for 56. It becomes 560
Divide that number by 2. then we get 560/2=280
Add a resultant number to the consequent of the first number after adding zero i.e., 280+560 = 840
Hence, the final answer is 840
Remember, multiplying any number by 9 is just multiplying as (10-1). You can follow the trick given below while multiplying any number by 9.
For Example:
Multiply 68 by 9, which means 68X9
Consider multiplying 9 as (10-1) i.e. 68X(10-1)
It becomes 680-68=612
Here, the final answer is 612
As per the previous year's trends, the difficulty level of questions asked in the IPMAT exam varies yearly. Therefore, learning some essential rules will help you solve any question in a matter of seconds.
The following are some important rules that you need to focus on while solving multiplication and division questions.
Number | Divisibility Test | Example |
2 | A number is divisible by 2 if its last digit is 0, 2, 4, 6, or 8. | 18 is divisible by 2 because the last digit is 8. |
3 | A number is divisible by 3 if the sum of its digits is divisible by 3. | 123 is divisible by 3 because the sum of its digits (1+2+3=6) is divisible by 3. |
4 | A number is divisible by 4 if its last two digits are divisible by 4 or have 00 for the last two digit | 132 is divisible by 4 because the last two digits form the number 32, which is divisible by 4. |
5 | A number is divisible by 5 if its last digit is 0 or 5. | 25 is divisible by 5 because the last digit is 5. |
6 | A number is divisible by 6 if it is divisible by both 2 and 3. | 24 is divisible by 6 because it is divisible by both 2 and 3. |
7 | To check divisibility by 7, take the last digit, double it, and subtract it from the rest of the number, if the result is divisible by 7 (including 0), then the number is divisible by 7. | 133 is divisible by 7 because if you double the last digit and subtract it from the rest of the number you get 13-6=7, which is divisible by 7. |
8 | A number is divisible by 8 if its last three digits are divisible by 8 or it has 000 for its last three digits | 1232 is divisible by 8 because the last three digits form the number 232, which is divisible by 8. |
9 | A number is divisible by 9 if the sum of its digits is divisible by 9. | 234 is divisible by 9 because the sum of its digits (2+3+4=9) is divisible by 9. |
Mastering quick multiplication and division tricks is essential for performing well in the IPMAT exam. These techniques not only save valuable time but also enhance accuracy, giving you a significant advantage in the quantitative section.
By incorporating these shortcuts and essential formulas into your IPMAT preparation, you can confidently tackle the exam and maximize your scores.
