There were 4 kids playing outside your house. Suddenly, the ball flies through your window, breaking it. You collect statements from all of them. You know the kid who broke your window is lying. However, an unknown number of the other kids might be lying too. Find out who broke the window.
A: I didn't break a thing!
B: I broke the window. Sorry.
C: Don't be mad at A, he didn't do anything.
D: B didn't break the glass.
Who broke it, and why?
D broke the glass, because it is the only lie that conflicts with another lie (B says "I broke the window", but D says that B didn't do it). "A" says they did not break anything and C confirms that.
ReplyDeleteB didnt break the window obviously, cause the guy who did break it is lying. Which means that D is telling the truth also. Since both of these guys are telling the truth, they can't be the window breaker.
ReplyDeleteSo its down to A and C. We know one of the HAS to be lying. If C is lying, then A is also lying. If A is lying, C is also lying. Therefore they are both lying. If you look at both of their statements, it is clear that A is the window breaker, and C is just a loyal friend.
A is the Perp.
I agree with Andrew.
ReplyDeleteI also think it's A.
ReplyDeleteA did it.
ReplyDeleteAll you really know is the one who did it is lying.
I just wrote out the logic, but seems to me that Andrew already did. So, I'll just leave Andrews answer.
The anwer is C. If you look at it for a while you can tell that that is the one.
ReplyDeleteC did it and here is why... We know B and D is out. So what C said is "Don't be mad at A, he didn't do anything." the lie for C is "anything" A did, he played with the kids so he did something, but "didn't break a thing!" he was part of the event that caused the breakage, but he didn't throw the ball. So who was Lying only B and C and we know B didn't do it.....Ya feel me...It's all Good.
ReplyDeleteB broke the window, but D is lying. B said he broke the window and D says he didn't so since none of the other kids said they broke it it was obviously B, but D was the kid that lied. The question was to figure out who broke the window not who was lying.
ReplyDeleteD broke the glass, because it is the only lie that conflicts with another lie (B says "I broke the window", but D says that B didn't do it). "A" says they did not break anything and C confirms that.
