"Still" implies that the original number is a square number. In that case, the answer is as follows:

There is no number such that it is a perfect sqiuare and that the number increased (or decreased) by 10 is also a perfect square.

And if you do not limit it to perfect square then every non-negative number is a square with the number that is 10 more also being a square.
