Is n an integer?

1. 2n is an integer.
n could be 1 or 1/2. In one case, the number n is an integer, and in another option, it is not.
Insufficient
2. 5n is an integer.
n could be 1 or 1/5. In one case, the number n is an integer, and in another option, it is not.
Insufficient

On combining information from both the statements, we can certainly say that the only option when
2n and 5n are both integers, n has to be integer(Sufficient) (Option C)
Hope that helps!
