Have been sick these past few days. So a quick one for now.
Are there two seven digit numbers, each with the digits 1,2,3,4,5,6,7 used exactly once such that one divides the other?
For example with two digits 1,2, the possibilities are 12 (twelve) and 21 (twenty one).
Try solving this mentally without using any pen/paper etc.
