What to Expect from this Article? - When appearing for competitive exams with aptitude as the main subject it is very obvious to be concerned about solving questions in time.
If you are an aspirant for the IPMAT exam but worried about how to perform calculations in less time, you are at the right place.
Learn the different techniques for solving multiplication and division tricks for competitive exams. Solve questions faster by multiplication short tricks to save your time and attempt all the questions.
This post shall guide you through short tips and tricks for solving multiplication and division questions in the IPMAT exam.
Why Learn Quick Multiplication and Division Tricks?
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.
Now, let us understand how to multiply and divide numbers using simple tricks from the post below.
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.
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
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
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.
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.
Consider 861 (8+6+1=15)
15 is divisible by 3. Therefore, 861 is also divisible by 3

Consider 1600 divided by 4
The answer is 400
225 divided by 5
The answer is 45
Consider whether 9522 is divisible by 9 or not.
18 is divisible by 9. Therefore, 9522 is also divisible by 9
To divide any number by 5, replace 5 with 10/2
Let us take 144/5, then 144/(10/2)
Now its become 144X2/10 = 288/10
The final answer is 28.8
