Riddle
Here’s a riddle i found somewhere:
There’s a club. Anyone can join the club.
If they can answer the doormans question.
A man who wants to join stands near the door and listens to the doorman.
A member walks up to the doorman and the doorman says,
“Twelve.”
The member replies, “Six.”
The doorman lets him in.
Another member walks up to the doorman. The doorman says,
“Six.”
The member replies, “Three.”
Feeling confident, the man wanting to join walks up to the doorman.
The doorman says, “Ten.”
The non-member replies, “Five.”
The doorman tells him to leave.
Why?
I haven’t figured out the answer myself yet - but I hope I eventually do. Meanwhile, you may comment if you have a hint of some sort or think you’ve got the answer

Of course, they use the number the doorman say as the argument to secret function f(x)=(x-12)(x-6)+x/2 Thus, the answer is of course -3
That’s the kragnir sollution. There are an infinite amount of other sollutions.

How… evil. But, to honest, I don’t really think that that’s the Kragnir way, but whatever.

It was all prepared beforehand as viral advertising for the club.

Seriously, I CAN’T solve it. It seems to be easily solved by small kids.

Another solution is
(x div 6) * 3 = y
or
div(x,6) * 3 = y
But the real one is that since twelve contains six letters and six contains three letters, the real answer is three since ten also contains three.

twelve = 6 characters
six = 3 characters
thus, ten = 3 characters.
