Guess my number (Posted on 2004-09-24)

I'm thinking of a number.

if it is not a multiple of 4, then it is between 60 and 69
if it is a multiple of 3 it is between 50 and 59
if it is not a multiple of 6 it is between 70 and 79.

What is the number?

Hmmm...

This one is fairly simple because the number must lie between 50 and 79. So guessing and checking is plausible. But it is still possible to go about it systematically.
