    Any quick way to solve this. I got this question on gmatprep and
    ended up fumbling (and moving on in the interest of time).

    Upon reviewing I found out what the error was on my part but
    would like to hear alternate approaches to attack this kind of problem.

    1 is sufficient
    it refers to a number of the format 6k+3 (k an integer)
    [ a number not divisible by 2 can be represented 2k+1
    when this number is divisible by 3 it can be represented 3*(2k+1)
    ]

    so when divided by 6 it will leave a remainder of 3

    2 is also sufficient
    it refers to a number of the format 12k+3 (k an integer)
    which leaves a remainder of 3 when divided by 6
