How many numbers are between 1 and 1000?
I would go with elimination of one character from a base 10 numbering system gives you a base 9 numbering system. 9^3 = 729 permutations of a base 9 numbering system (a system with no number 3) with 3 digits, since 10^3 = 1000; 10^3 – 9^3 = 271 thus 271 numbers have a 3 in them.
