If n and k are positive integers, is n/k an even integer?
1. n is divisible by 8
2. k is divisible by 4.
IOM it's C.
1. n is divisible by 8
2. k is divisible by 4.

First off, neither statements are sufficent alone b/c each provides info about one of the variables.
Putting the statments together--pick multiples of 8 for n and 4 for k:
n=8, 16, 24, 32, 40, 48 etc.
k=4, 8, 12, 16, 20, 24, 28, etc.
So, put the statements together:
-If n=8 and k=4-->2-->even
-If n=8 and k=8-->1-->odd
INSUFFICIENT. Choice E.
Or, without writing out any of the multiples, you can just say that there are too many possible scenarios for n and k where some quotients are even and some are odd, so together but statements are insufficient.
