We’re white folk over here. If I buy a house with bad wiring, rather than label the mess, I rewire it.

phoneutria · September 12, 2015, 5:15pm

and I hope we’re talking wall switches here, because if the switch board for the whole hose only has 3 switches, I’m going to go ahead and say that the wiring problem is a little bigger

Treat two switches as one. The rest is axiomatic.

That is right. =D>

So now we can go on with the next riddle.

Are you ready for the next riddle?

Two Liars.

Five persons A, B, C, D and E chat:
[list][list][list][list][list]A: “B lies if and only if D is telling the truth.”
B: “If C is telling the truth, then either A or D is a liar.”
C: “E lies, and also A or B lie.”
D: “If B is telling the truth, then A or C too.”
E: “Among the persons A, C and D is at least one liar.”[/list:u][/list:u][/list:u][/list:u][/list:u]
Two persons are lying. Which?

What is your precise answer?

[tab]I guess that your red and blue colored letters have a meaning. What is your conclusion, your exact answer?[/tab]

James_S_Saint · September 13, 2015, 12:44am

[tab]You can’t READ??

Hmmm… guess that is YOUR riddle to solve [/tab]

It looks a lot like he is Leibnitz

Sorry I am on the wrong riddle, but am I close?

Arminius · September 13, 2015, 1:15am

I am not the only one who reads your posts.

[tab]It is no problem to interpret your diagram, but: I am not quite sure whether all ILP members are capable of understanding your diagram.[/tab]

James_S_Saint · September 13, 2015, 1:27am

[tab]That is why I didn’t make it more obvious. [/tab]

So, okay, to what were you referring?

The first riddle.

I made a mistake reading e, therefore a or c instead of a or b. Duh. I am going to delete my previous points to make it less confusing.

[tab]A liar
C true
E liar
D true
B true[/tab]

Arminius · September 13, 2015, 12:33pm

That is also false.

[tab]In your previous post you were saying that A and B were liars, but that is not possible that both A and B are liars. Now you are saying that A and E are liars, but it is also not possible that both A and E are liars.[/tab]
Please try again.

B and C are lying.

With love,
Sanjay

Arminius · September 13, 2015, 2:05pm

Hello, Sanjay.

[tab]Your answer is false. Unfortunately. It is not possible that both B and C are liars.[/tab]

James_S_Saint · September 13, 2015, 2:24pm

Sanjay, we are supposed to put our answers in a tab so that others don’t see it unless they want to.

And I can see that this puzzle also has a communication issue that depends on interpretation.[tab]A: “B lies if and only if D is telling the truth.”
If that is a lie, all you know is that B is independent of D.

B: “If C is telling the truth, then either A or D is a liar.”
If that is a lie, then if C is telling the truth, both A or D are true.

C: “E lies, and also A or B lie.”
If that is a lie, either E is true or both A or B are true.

D: “If B is telling the truth, then A or C too.”
If that is a lie, then if B is telling the truth, both A and C are lies.

E: “Among the persons A, C and D is at least one liar.”
If that is a lie, A, C, and D are true.[/tab]
