If k, m, and t are positive integers and k/6 + m/4 = t/12 , do t and 12 have a common factor greater than 1 ?
(1) k is a multiple of 3.
(2) m is a multiple of 3.

(1) 2k is a multiple of 3 (2*multiple of 3) but we know M is greater than 1. And thus 3M is also a multiple of 3. So we can tell that t does have more than one common factor.

Same with (2).

Should be (D). My bad.. didn't read the question properly

Although I solved it by substituition , takes lot longer. _________________
