At the entrance to a members club stands a stranger seeking
admission. A friend told him that it's easy to get in. You
just have to answer a question corrcetly! Answering wrong,
however, will result in being shot!
To live a little longer, the man waits in a back alley near
the entrance for people to go in. After a while a man comes
to the entrance. The door warden asks him: "Twelve?" to
which he replies "Six!" and goes in.
"That's easy." our friend thinks, but he waits a little longer.
Another man comes to the door. "Six?" the door warden asks,
to which he replies "Three!" and goes in.
"That's too good to be true" our friend thinks, and he was
right. Because, when asked "Four?", he answered "Two!" and
was found dead in the alley.
What was the correct answer?
