Well, do it!
Ones Tens Hundreds etc.
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 09.
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.
