Suppose you have four numbered tiles, one with a 3 on it, one with a 4, one with a 5, and one with a 6.?

Question

What is the largest four-digit number that can be formed by these tiles that is not evenly divisible by 9?

Answer 1

6543.

It is always divisible by 9.

Answer 2

6543

Answer 3

9543 but that would involve turning around the 6 tile upside down

Answer 4

9,543...!

Answer 5

Man, I dont know. I've tried so many different combination but they are all divisable by 9

Answer 6

you can do 9543 but that would involve turning around the 6 tile

if you use all the numbers the right way round then there are no numbers (that i can find)

hope you can find some!

Answer 7

3+4+5+6=18 18/9=2 which means it's impossible. if you flip the 6 over to a 9, the largest number would be 9543.
