According to the question 9999 - n is even. Hence, n is odd.

8n ≥ 9999 - n to yield an exact integer, so n ≥ 1111

Now,  Plug and play with numbers 

Put n = 1111 This works.

(9999 - n)k = 8n for some positive integer k.

9999k = (k + 8)n

n = 1111 is the only possible solution.

The answer is 1.
