Jon wanted to enter an exclusive club, but he didn't know the password. He waited by the door and listened. A club member knocked on the door and the doorman said "twelve". the member replied "six" and he was let in. A second member came to the door and the doorman said "six" and the member replied "three" and was let in. Jon thought he had heard enough. He walked up to the door with confidence. The doorman said "ten" and Jon replied "five." He was beaten up and thrown out on the street for not having the right password. What was the right answer and why?
Answer: The correct answer was "three" because it is the number of letters that make up the word "ten".
