What Should He Say?
Riddle: Chris wants to enter an exclusive club, but the security guard in front of the door always asks for a password. Chris decides to eavesdrop on clubgoers, and this is what he sees: A woman walks up to the security guard. The guard says "12", and the woman replies "6". The woman is granted access. A man walks up to the security guard. The guard says "6", and the man replies "3". The man is granted access. Another woman walks up to the security guard. The guard says "10", and the woman replies "5". This woman is NOT granted access. Chris thinks he's seen enough, and he walks up to the security guard. The guard says "4". What should Chris say to get into the club?
Answer: To get into the club, Chris should say "4". The task was not to divide the number by two (after all, not all numbers are divisible by two). Instead, the task was to say how many letters are in the number the security guard says. "Twelve" has 6 letters. "Six", in turn, has 3 letters. "Ten" also has 3 letters, so the second woman should have said "3", not "5". Chris should say "4" because "four" consists of 4 letters.
