1) 4*x*k = 4 => x*k=1 not suff to determine if x>k
2) 27 *x* k = 81 => x*k=3 again not suff to determine if x>k

E.

Actually 1) & 2) should not contradict with each other. here they do.
one says x*k=1 and other says x*k=3

I was wondering whether there is any catch. How ever, as others noticed (1) and (2) contradict with each other. In GMAT DS (1) and (2) never contradict.
