ganesh posted this problem a few months ago:

"Two dices are marked with numbers from zero to nine on each face.

The two dices are meant to display all the dates in a month from 01 to 31.

Remember, single digit dates would have to be shown as 01, 02, 03 etc.

That is, one dice should show zero and the other 1 or 2 or 3 and so on.

The two dices can be interchanged i.e. placed in any order.

What would be the numbers written on the six faces of the two dices???"

I would like to know how to prove this situation is impossible if you don't count 6 and 9 as the same. Although I have a crude prose proof, I want to use just math and variables. How can I do this? Thanks

Jack
