9 should be added to 1015 to make it a perfect square.
Because when we do the square root of 1015 by division method we get 31 and square of 31 is 961 which is less than 1015 so we will do square of next consecutive number which is 32 then the square of 32 is 1024 which is greater than 1025 and difference between 1024 and 1015 is 9.
So, the answer is 9.
