Note: The best answer I will choose for this is the one that:
a. answers the riddle with the correct answer
b. has the least number of moves that really works
c. isn't too long, but gives all the steps with easy-to-read grammar.
It will not be the first one it will be the best one. Now onto the riddle.
You have 24 [insert item of choice here-I'll be using coins]. 23 of them are normal, but 1 of them is either heavier or lighter. This changes each time you do the puzzle. Using a balance scale (shows whether both sides are the same weight or if one is heavier), what is the least number of times you have to balance the [coins] to find out which is different, and to tell me whether it is heavier or lighter? This must work each time, whether the different [coin] is heavier or lighter. Take your time, I will not choose the first answer as the best answer, and good luck!
