Question

Find the square of the number $105$ using Vedic Mathematics.

• A. $11125$
• B. $11235$
• C. $11325$
• D. $11025$

Answer 1

Answer: (D)

$11025$

To find $(105{)}^2$

$100$ is the nearest power of $10$ which can be taken out as base.

Deviation is obtained by $105-100=5$

Left side of the number is $105+5=110$

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 $11025$.
