If N is an integer, is 36/N an integer?
(1) N is a multiple of 9.
(2) 9 < N < 27
1. If N is a multiple of 9, 36/N can or cannot be an integer.
If N = 9, 18, or 36 - 36/N is an integer. Else it is not an integer
(Insufficient)2. In this range 9 < N < 27, is N = 10, 36/N is not an integer.
But 36/18 is an integer. Hence, this statement alone isn't enough
(Insufficient)On combining the information from both the statements,
N can take only one value
18 and 36/N is an integer
(Sufficient - Option C)
