How much wood can a woodchuck chuck, when a woodchuck woodchucks wood?
Peter Piper picked a peck of pickled peppers, if Peter Piper picked a peck
pickled peppers, then how many peppers did Peter Piper pick?
In reality, it's the same question. I hate these questions, because there is NO ANSWER!!! Or a better explanation would be -- you have not given enough information to answer the question, therefore, there is no answer.
It's a dumb answer, so my answer was 23 (which was just as enlightened as the question and just as dumb).
