Question

Q12. Find the greatest number of three digits which is a perfect square.
​

Answer 1

Trial and error:

30² = 900

31² = 961

32² = 1024

So, the answer, I hope, comes out to be 961

Answer 2

Hey! mate, GOOD AFTERNOON☺

We know that 999 is not a perfect square as it leaves 38 as remainder. So if 38 will be addede to 999 then it will become a 4 digit number. Therefore to find the largest 3 digit perfect square we will subtract 38 from 999. Hence 961 isthe largest 3 digit perfect square whose squareroot is 31.
