    We have:

    I am a three digit number. My tens digit is twice my ones digit, my hundreds digit is twice my tens digit. I am greater than 500. Who am I?

    How about 631?

    631 is > 500.

    This is a math riddle not a math question. There are several answers.

    Ahh, but the ratio of
    unit digit:tens digit:hundred digit
    must be 1:2:4

    631 does not fit that ratio

    drwl's answer of 841 does, and is the only one > 500

    Good point and you are right.

    I did not capture that part of the question.

    Good looking out, Reiny.

    Thanks for the correction.
