Nope! :wink:
2 door teaser answer:
You ask either of the 2 guards : "If I want the S54 with Supercharger, what door will the other guard say I should go through?"
Let's say that the Door A leads to the Supercharger....
If you ask the honest guard, he will honestly tell you that the other guard will lie and tell you Door B (to the crusher).
If you ask the lying guard, he will lie and tell you the honest guard will tell you Door B (to the crusher).
They've both said Door B -- the one that leads to the crusher.
So, you ask the question... and then drive through the OTHER door - Door A (to the Supercharger)
Ste said:AhhVery good. I approached it from a maths point of view. Mine would still work though so it's not wrong
Erm...sorry, but no - yours would not work. :wink:
If you simply asked your question "If I ask you which door to go through, what would you say"? then....
Let's say again that the Door A leads to the Supercharger....
If you ask the honest guard, he will honestly tell you to go through Door A (to the Supercharger).
If you ask the lying guard, he will lie and tell you to go through Door B (to the crusher).
BUT you don't know which is the honest guard and which is the lying guard, so with your question, how would you know to go through Door A with your ONE question then!?

Correct - you have to ask either guard what the other guard would say
EDIT: I've just realised that this is your teaser, so you know its correct

No. I put my question within a question. I'm not saying "Which door should I go through" im asking them what they'd say IF I asked the question. An ask within an ask.
If I ask truthful guard "What door should I go through", he'd say A.
If I ask lying guard "What door should I go through, he'd say B.
But if I ask the truthful guard "What would your answer be if I asked you the question "What door should I go through", he'd truthfully tell me he'd say A if asked the question.
However, if I ask the lying guard "What would your answer be if I asked you the question "What door should I go through", his answer to the question itself would be B, but because i'm asking him a question ABOUT a question, he wouldn't tell me truthfully what his answer would be, so he'd have to lie and say A.
Thus I'd know to go through A. A positive and a positive equals a positive, but a negative and a negative also equals a positive
By the seaside...

Thus I'd know to go through A. A positive and a positive equals a positive, but a negative and a negative also equals a positive
Hmmm.....I suppose this makes some sense, but I can assure you that I would deffo not take the risk of my Z4 being crushed with your question heavily relying on the lying guard correctly interpreting your question, to realise that they had to lie about their own lie! :?
