Solution :

The least number which must be added to 1500 so as to get a perfect square number.

We have to find the most closest perfect square in between the number lies.

i.e. 1444<1500<15211444<1500<1521

38^2<1500<39^2382<1500<392

We need to add 39^2-1500392−1500 in the number.

Required number is R=39^2-1500R=392−1500

R=1521-1500R=1521−1500

R=21R=21

If we add 21 in the number it will make a perfect square of 39.
