There is a club. There are many people who are members of that club. On the entrance of the club there is a guard. He gives club members a number when they want to enter. The club member gives him another number back, related to the first. If the guard thinks that the answer is correct then he allows them to enter into the club, otherwise does not.
First, a man A comes to the guard. The guard gives him the number 12. The man A responds with 6. The guard allows him to enter.
Second, a man B comes to the guard. The guard gives him the number 6. The man B responds with 3. The guard allows him to enter.
Third, a man C comes to the guard. The guard gives him the number 8. The man C responds with 4. The guard does not allow him to enter.
Can you tell, what would've been the correct response?
