a guy is waiting outside of a VIP club and is trying to gain access. he decides to listen to what people say to the doorman
to get in. he finds that the doorman will say a number, and that the customer will reply with a number to get in:
the first guy walks up, and the doorman says: “12″
the guy replies: “6″
and the doorman lets him in
the second guy walks up, and the doorman says: “6″
the guy replies: “3″
and the doorman lets him in
so the original guy thinks he has it figured out and walks up to the door. the doorman then says: “10″
so the man answers: “5″ – but he is not let in.
what should he have said to been given access to the VIP club?
