3 digit multiplication trick


A person who knows math tricks certainly has an edge over the others.With the ability to rapid do mental calculation one will not only be able to score higher marks in competitive exams but will also enhance his mental sharpness enormously. Its fun to calculate this way after all, steps of calculation need not be shown on paper!




Below we shall discuss one such multiplication trick wherein you will be able to multiply any two 3 digit numbers easily within seconds.
One thing to remember here is that both the numbers should be close to 100.The closer they are the easier it is to multiply.

Here are steps to do the 3 digit multiplication in detail

Step 1:Find the difference of each of the numbers from 100
Step 2:Multiply the differences that you found in step 1 to get the unit’s place digit
Step 3:Add the differences of both the numbers to 100 and place them to the left of the result obtained in step 2.

Let us now consider an example to understand better

Example 1: 102 x 103
Here we notice that both the numbers are close to 100
We shall apply the technique that we learnt 

Step 1:First we find the differences of the numbers
We observe that 
102 is 2 more than 100 so the difference is 2
103 is 3 more than 100 so the difference is 3

Step 2:Multiplying the differences 
we get,
2 x 3=6 which is the unit’s place digit.

Step 3:Now to find the rest of the number adding the differences to 100 
we get,
2+3+100=105

Placing 105 to the left of the result obtained in step 2(6)
we get 
102 x 103=10506

Ans 10506


Try multiplying the below numbers using the above trick and see how fast you are able to do it
(1)101 x 102
(2)102 x 104
(3)103 x 104
(4)104 x 105
(5)105 x 106
(6)106 x 107
(7)107 x 108
(8)108 x 109

Shortcut to square any number from 100-120
Shortcut to square any number from 100 to 120 using base method. Base method is popularly used to find square of numbers when the numbers are close to a base.By choosing the right base you will arrive at your answer quickly.
So whenever you see 102,101,112,106 it should strike to you immediately .


Hey! this is quite close to 100 so let me take the base as 100 and see if I can get the answer soon.

Here we discuss the shortcut method to square any number from 100 to 120 using the base method.

Lets go through the steps now

Examples

Example 1: Find square of 102 in seconds?

Step 1:Take 100 as base and see how far the number is from 100.
Add the given number and its deviation.
Lets say you need to square 102.
Here you can notice that the number is 2 more than 100.
Adding the given number(102) and its deviation(2)
we get,
102+2=104

Step 2:Square the deviation(2)and place it next to the result obtained in step 1.
Squaring we get,
22=4

Ans 10404

Example 2: Find square of 103 in seconds?

Step 1:Take 100 as base and see how far the number is from 100.
Add the given number and its deviation.

Here you can notice that the number is 3 more than 100.
Adding the given number(103) and its deviation(3)
we get,
103+3=106

Step 2:Square the deviation(3)and place it next to the result obtained in step 1.
Squaring we get,
32=9

Ans 10609

Example 3: Find square of 104 in seconds?

Step 1:Take 100 as base and see how far the number is from 100.
Add the given number and its deviation.

Here you can notice that the number is 4 more than 100.
Adding the given number(104) and its deviation(4)
we get,
104+4=108

Step 2:Square the deviation(3)and place it next to the result obtained in step 1.
Squaring we get,
42=16

Ans 10816

Decoding words trick for bank exams

Decoding words trick for bank exams

Decoding words trick to your rescue to help you decode words quicker.These type of problems are often asked in Reasoning ability section of bank exams. Knowing the technique to decode letters will help in arriving at the answer within seconds.
There are different types of decoding.

Today we shall see problems of the following type 
In a certain code, a word is 
written as some word(code). How is another word written in that code?

Examples of Decoding words trick to solve reasoning problems


Let us see the steps to decode the letters of word 

Step 1:First of all write down all the alphabets from A to Z in the following manner
A=1,B=2,C=3,D=4,E=5,F=6,G=7,H=8,I=9,J=10,K=11,L=12,M=13,N=14,O=15,P=16,Q=17,R=18,S=19,T=20,U=21,V=22,W=23,X=24,Y=25,Z=26

Step 2:Now write the given word and the code in the form of numbers by substituting the value of the letters with their corresponding numbers.
Step 3:Compare the letter and the code and try to identify the pattern it is following.
       To identify the pattern check 2 things
       (a)Is there a change in the order of the letters or not
       (b)After substituting each of the letters with numbers see if the number increased or decreased and by how much. Step 4:Now write the another word that is to be written in that code in the form of numbers as you did in step 2.

Step 5:Apply the pattern that you identified in step 3 to the word to be decoded.

Step 6:Substitute the letters corresponding to the numbers of the pattern


Let us consider an example to understand better

Example 1:In a certain code, ‘TRICK’ is written as ‘SQHBJ’. How ‘LIGHT’ is written in that code?

Step 1:We write the Alphabetic series as
A=1,B=2,C=3,D=4,E=5,F=6,G=7,H=8,I=9,J=10,K=11,L=12,M=13,N=14,O=15,
P=16,Q=17,R=18,S=19,T=20,U=21,V=22,W=23,X=24,Y=25,Z=26

Step 2:Substituting the numbers in the word and the code
TRICK-20,18,9,3,11
SQHBJ-19,17,8,2,10

Step 3:Comparing the order of the letters of the word with the code, we notice that
there is no change in the order of the letters
Next we check if there is increase or decrease, we find that
Pattern here is 19=20-1,17=18-1,8=9-1,2=3-1,10=11-1
We have successfully identified the pattern as decreasing by 1. 

Step 4:Substituting the numbers in the word to be decoded
LIGHT-12,9,7,8,20

Step 5:Applying the pattern we identified in step 3 to the word LIGHT we get
         12-1=11,9-1=8,7-1=6,8-1=7,20-1=19
         we get,
         11,8,6,7,19

Step 6:Substitute the letters corresponding to numbers of the pattern


Ans Decoded word of LIGHT will be KHFGS

Vedic math trick to check multiplication

Vedic maths is the ancient mathmematics discovered from the vedas by Sri Bharati Krsna Tirthaji. My Salutations to the Swamiji for providing us with such a useful and magical tool to solve complex mathematical problems. Vedic math trick to check multiplication is one such amazing trick. This Vedic math trick is an easy method to check if the multiplication of any two given numbers is done correctly.

Vedic math trick to check multiplication steps

Let us now see the how it is done in the steps below.

Step 1:Find the sum of the digits of the numbers to be multiplied separately.

Step 2:Find the sum of the digits of the answer you got on multiplying each of the numbers.

Step 3:Multiply the results obtained in step 1 and find its sum of digits.

Step 4:Compare the sum of digits obtained in step 2 with the sum of the digits obtained in step 3.
If both are same then it means you have multiplied correctly.

Examples
Let us consider an example to understand better

Example 1: 105 x 140=14700
We want to check whether 14700 is the correct answer.
Here is how we can check it
Step 1:Finding sum of the digits of 105
         105=1+0+5=6
         Finding sum of digits of 140
         140=1+4+0=5
Step 2:Finding sum of digits of the answer 14700
          14700=1+4+7+0+0=12=1+2=3

Step 3:Multiplying the results obtained in step 1 we get,
          6 x 5=30
        finding sum of digits of 30
        30=3+0=3

Step 4:Comparing result obtained in step 2 with result obtained in step 3 we notice that
Sum of digits in the both the cases is 3.

Hence, we can conclude that our multiplication is right and we arrived at the correct answer.
