Thought this might be fun to share a few of these
A man wants to get into a night club, the bouncer stops him and says 7, the man has no idea how to answer and walks away, he stands over the road and watches another clubber approach the bouncer who says 12, the clubber replies 6 and gets let in. A second clubber approaches the bouncer who says 6, the clubber replies 3 and gets let in. The man now approaches the bouncer again who says 10, the man says 5 and is denied entry. explain
