• A. $100489$
• B. $100289$
• C. $998256$
• D. $Noneofthese$

Answer 1

Answer: (A)

$100489$

We know that, $100000$ is lowest $6$ digit number.

From above long division method we can see that it is not perfect square.

Here, Quotient $=316$

${316}^2=99856$ but it is $5$ digit number.

Let us take square of $317$

${317}^2=100489.$

$\therefore$ $100489$ is least number of six digit which is perfect square.
