"A five-digit number N consists of 3 distinct nonzero digits" vs. "N equals the sum of all possible 2-digit numbers made up of 2 of its 3 digits". The former means N is a 5-digit number while the latter means there are only 6 possible 2-digit numbers made up of 2 of its 3 nonzero digits and N never equals the sum of these 6 2-digit numbers. What does exactly the number N refer to?

The problem was meant to say "three-digit number". It should now display correctly.
