    Please see the attached image for a problem on number theory. The questions that I will be posting in this forum are based on concepts tested in recent GMAT tests.

    You will need to be logged in to see the problem statement because it is posted as an image. It makes it easier for me to write math using free hand software.

    I will post the answer in few days.

    Cheers,
    Mark
