S t e v e Posted April 12, 2011 Share Posted April 12, 2011 Can you solve this riddle? Which suspects are innocent or guilty of the crime? A, B, C and D. These are the facts; -If A is guilty then B is an accomplice. -If B is guilty then either C is an accomplice or A is innocent. -If D is innocent, then A is guilty and Cis innocent. -If D is guilty, so is A. So, who´s guilty and who´s innocent and how do you work this out?????? Link to comment Share on other sites More sharing options...
Guest FarnsBarns Posted April 12, 2011 Share Posted April 12, 2011 I believe C is guilty and A, B, and D are innocent. Every other option I could think of caused a self contradiction. Edit: no that's wrong, start again. Edit 2: it seems to be an impossible catch 22. Edit 3: they are all guilty. Yep, that works, sling them all in prison!

Flight959 Posted April 12, 2011 Share Posted April 12, 2011 I believe B is guilty! as being guilty is the same as being an accomplice.. Link to comment Share on other sites More sharing options...
Guest FarnsBarns Posted April 12, 2011 Share Posted April 12, 2011 The ABC 'Twas midnight in the schoolroom And every desk was shut When suddenly from the alphabet Was heard a loud "Tut-Tut!" Said A to B, "I don't like C; His manners are a lack. For all I ever see of C Is a semi-circular back!" "I disagree," said D to B, "I've never found C so. From where I stand he seems to be An uncompleted O." C was vexed, "I'm much perplexed, You criticise my shape. I'm made like that, to help spell Cat And Cow and Cool and Cape." "He's right" said E; said F, "Whoopee!" Said G, "'Ip, 'Ip, 'ooray!" "You're dropping me," roared H to G. "Don't do it please I pray." "Out of my way," LL said to K. "I'll make poor I look ILL." To stop this stunt J stood in front, And presto! ILL was JILL. "U know," said V, "that W Is twice the age of me. For as a Roman V is five I'm half as young as he." X and Y yawned sleepily, "Look at the time!" they said. "Let's all get off to beddy byes." They did, then "Z-z-z." Link to comment Share on other sites More sharing options...
Guest FarnsBarns Posted April 12, 2011 Share Posted April 12, 2011 I believe B is guilty! as being guilty is the same as being an accomplice.. Then C must be in on it too. Link to comment Share on other sites More sharing options...

S t e v e Posted April 12, 2011 Author Share Posted April 12, 2011 they are all guilty 1 If A is guilty then B is an accomplice. 2 If B is guilty then either C is an accomplice or A is innocent. 3 If D is innocent, then A is guilty and Cis innocent. 4 If D is guilty, so is A. suppose A is guilty from 1) B is also guilty from 2) C would have to be an accomplice as we assume A is not innocent from 3) D can not be innocent, as this implies C is innocent, but from 2 we found he was an accomplis - so D=guilty 4) D=guilty implies A is guilty - this is consistent so if A is guilty, then B,C,D are also guilty secondly suppose A is innocent, then From 4) D can only be innocent - Guilt of D would imply that A is guilty, but we are assuming innocence from 3) A would be guilty because D is innocent (as proved in last statement) - this is impossible, we already assumed he was innocent A can not be innocent in any circumstance Link to comment Share on other sites More sharing options...
Daryl M Posted April 12, 2011 Share Posted April 12, 2011 I think it's clear that the evidence here is circumstantial. I move for an acquittal. Link to comment Share on other sites More sharing options...

lantis Posted April 12, 2011 Share Posted April 12, 2011 I come from Sweden so I say all are innocent and I guess that we must pay A, B, C and mrs D a find for accusing them before they got convicted. pardon my bed English :) Link to comment Share on other sites More sharing options...

jaxson50 Posted April 13, 2011 Share Posted April 13, 2011 Hang'em all and let God sort it out... Use the two bounce truth test, shove each one off a tall building, If they bounce twice they are guilty.. Or hear the evidence.. Link to comment Share on other sites More sharing options...
