Well, do it!


Thinking of a number. It has thousands, ones, hundreds, and tens. It looks like this:

ABCD - Where each of A, B, C, and D are from digits 0-9.

Twice as many thousands as ones. A = 2*D
Twice as many ones as hundreds. D = 2*B
Twice as many hundreds as tens. B = 2*C

This is not as tricky as it may look. Everything keeps getting bigger. There is only so much to do with that.

Working from the bottom.
If C = 0, then B = 0 and D = 0 and A = 0 and the number is 0000. I'm guessing that is unsatisfactory.

If C = 1, then B = 2 and D = 4 and A = 8 and the number is 8214. That looks okay.

If C = 2, then B = 4 and D = 8 and A = 16 and the number is (16)428. You tell me what's wrong with that.

I think it's done.
