According to the experts, learning formulas and short tricks would help you crack the quantitative section of the IPMAT exam easily.
In this post, we have provided the topic-wise important IPMAT Maths Formulas to help enhance your preparation levels.
So, why late! Scroll through the post to learn important formulae and perform calculations using these formulae in a matter of seconds.
Important Questions with Solutions for IPMAT Exam by SuperGrads
As we all know, the quantitative ability section plays a vital role in the IPMAT exam, and this is because it holds 60% weightage in the exam compared to other areas.
Each one of your preparation strategies may vary. However, focusing on formulae will help enhance your preparation for the IPMAT Maths section.
From the post below, let us go through the formulas based on number systems, square roots, cube roots, percentage, profit, and loss, etc.
Note:
In the above formulae, "n" or "a" or "b" or "c" are constants or variables with value as an integer > 0.
Product of two numbers a and b
(a*b) = Their HCF * Their LCM.
But a*b*c ≠ HCF*LCM

Note:
Co-primes
Two numbers are said to be co-prime if their H.C.F. is 1.
HCF of a given number always divides its LCM.
Methods of finding HCF of two or more numbers
The following are the three methods that are used to find the highest common factor of the given numbers:
Let us understand all these methods with examples from the post below.
Method 1: Prime Factors Method
Example:
If you have to find the HCF of 42 and 70.
Then 42 = 2*3*7
And 72 = 2*5*7
Common factors are 2 and 7 so, HCF = 2*7 =14.

Method 2: Division Method
Method 3: HCF of Large Numbers
Methods of finding LCM of two or more numbers
You can use the prime factors method to find the least common multiple of the given numbers.
Let us understand how to find the LCM using the prime factors method with the following example.
Method 1: Prime Factors Method

Example:
LCM of 8,12,15 and 21.
Now, 8 can be written as = 2*2*2 = 23
12 = 2*2*3 = 22*3
15 = 3*5
21 = 3*7
So highest power factors that occurred are: 23, 3, 5 and 7
LCM = 23*3*5*7
= 840.
You can follow the Toppers Tips to Crack IPMAT with a good score. The following are some of the important formulas from the simplifaction topics.
BODMAS Rule
Here are some rules of simplification given below-
B – Bracket (First of all, remove all the brackets strictly in the order (), {} and ||, and after removing the brackets, you can follow the below sequence)
O – Of
D – Division,
M – Multiplication,
A – Addition and
S – Subtraction
Modulus of a Real Number
Modulus of a real number a is defined as
|a| = a, if a > 0
= -a, if a< 0
Thus, |5| = 5 and |-5| = -(-5) = 5.
Vinculum (or Bar):
When an expression contains Vinculum, before applying the ‘BODMAS’ rule, we simplify the expression under the Vinculum.

Duplex Combination Method for Squaring
In this method, we either calculate the square by multiplying the same digit twice or perform cross multiplication.
Here are the following Duplex rules and formulas, please check below.
a = D = (a*a)
ab = D = 2*(a*b)
abc = D = 2*(a*c)+(b)2
abcd = D = 2*(a*d) + 2*(b*c)
abcde = D = 2*(a*e) + 2*(b*d) + (c)2
abcdef = D = 2*(a*f)2 + 2*(b*e)2 + 2*(c*d)2
Now I’ll make you understand the complete squaring procedure better with the help of examples.
Check out the example here :
We have to find out the solution of (207)2 instantly.
Then,
(207)2 = D for 2 / D for 20 / D for 207 / D for 07 / D for 7
(207)2 = 2*2 / 2*(2*0) / 2*(2*7) + 02 / 2*(0*7) / 7*7
(207)2 = 4/0/28/0/49
(207)2 = 4/0/28/0/49
(207)2 = 4 / (0+2) / 8 / (0+4) / 9
(207)2 = 4 / 2 / 8 / 4 / 9
(207)2 = 42849.
Easy Method to calculate Cube
Let us understand the cube method with the help of the following example:
Find out the result of (16)3
Here, we will write the 16 power 3 in the following way:
1 6 (6*6) (6*6*6)
6*6 = 36
6*6*6 = 216
Therefore, the final value = 1 6 36 216
The following are some important formulas for the problems based on ages for the upcoming IPMAT Entrance Exam.
Quicker Methods – To find out the son’s age, use this formula.
Son’s Age = t1 (x-1) / (x-y)
Son’s Age = (z-1)t1 / (y-z)
Son’s Age = [(z-1)t2 + (x-1)t1] / (x-z)
