Difference of Other Digits is Odd

Multiplying Two Numbers Ending With Five When Difference Of Other Digit is Odd:  This method is used when we have two numbers ending with five and the difference of the other digit is odd  Such type of Techniques of Vedic Maths help us to perform calculations in a much faster way.  Mastering such type of techniques is very essential in Competitive Exams where time is very precious

We will take following steps to multiply such numbers

For Example: We have to multiply 85 with 55.

As both the numbers are ending with five and the difference of other digit is odd

Step 1: As the diffrence is odd we will append 75 in the answer.

Answer = ____75

Step 2: We will multiply the other digits. In this case we will multiply 8 with 5

Result 1 = 8 X 5 = 40

We will now add the digits.That is Result 2 = 8 + 5 = 13

We will divide the Result 2 with 2. We get Result 3= 13/2 = 6.5

As Result 3 is in decimals we will use the integral part

Result 4 = Result 1 + Result 3 = 40 + 6 = 46

We will prefix the Result 4 in the answer

Answer= 4675
