Find the square of the number $95$ using Vedic Mathematics.

maths vedic mathematics square roots using vedic maths square and square roots using vedic mathematics history of mathematics

  1. $9025$

  2. $9125$

  3. $8025$

  4. $8125$

Show answer
Correct Option: A
Explanation:
To find $(95)^{2}$
$100$ is the nearest power of $10$ which can be taken out as base.
Deviation is obtained by $95-100=-5$
Left side of the number is $95-5=90$
Since, the base is $100$, the right hand side number will have two digits and that can be obtained by taking square of deviation $-5$. So, $(-5)^{2}=25$.
Thus, the right side number will be $25$.
Hence, the required number is $9025$.
