**Guido**, Sunday, February 17, 2008 at 10:42amWe 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.

**Reiny**, Sunday, February 17, 2008 at 11:24amAhh, 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

**Guido**, Sunday, February 17, 2008 at 1:14pmGood point and you are right.

I did not capture that part of the question.

Good looking out, Reiny.

Thanks for the correction.
