## The King and the Poison

Logic puzzles require you to think. You will have to be logical in your reasoning.

 Puzzle ID: #1416 Fun: (3.11) Difficulty: (2.84) Category: Logic Submitted By: Yanivster Corrected By: MarcM1098

In a far away land, it was known that if you drank poison, the only way to save yourself is to drink a stronger poison, which neutralizes the weaker poison. The king that ruled the land wanted to make sure that he possessed the strongest poison in the kingdom, in order to ensure his survival, in any situation. So the king called the kingdom's pharmacist and the kingdom's treasurer, he gave each a week to make the strongest poison. Then, each would drink the other one's poison, then his own, and the one that will survive, will be the one that had the stronger poison.
The pharmacist went straight to work, but the treasurer knew he had no chance, for the pharmacist was much more experienced in this field, so instead, he made up a plan to survive and make sure the pharmacist dies. On the last day the pharmacist suddenly realized that the treasurer would know he had no chance, so he must have a plan. After a little thought, the pharmacist realized what the treasurer's plan must be, and he concocted a counter plan, to make sure he survives and the treasurer dies. When the time came, the king summoned both of them. They drank the poisons as planned, and the treasurer died, the pharmacist survived, and the king didn't get what he wanted.
What exactly happened there?

DillKill47 Feb 09, 2002 That was cool Zazzar Feb 10, 2002 In fact is WAS cool... reading the answer that is. For I could not solve it... and not unlike Mr. Owl, I "bit" into the chewy center after only 3 licks. captbob61 Mar 26, 2002 I came up with a few different possible scenarios, but that is tough! Really good presentation of the problem too. Great job! rohddawg Mar 26, 2002 sweet!!! pusandave Mar 28, 2002 Fun and well written! comet16 Mar 30, 2002 Awesome puzzle!!! emilymonkeymaia Apr 11, 2002 Wah cool! arij Apr 12, 2002 this ones so good that I just cannot tell you!

SandPman May 12, 2002 One of the best I have seen on here - very good. O_wise_one May 19, 2002 Very long, but it was WELL worth the wait, did U see that somewhere, or did U make it up? Either way, VERY good and VERY entertaining! andy1608 Jun 05, 2002 Note for potential treasurers (and pharmacists I guess!) If you take a poison which is slightly stronger than the poison you drink before going in, you'll be OK and the pharmacist will die. (as long as he still brings water.) Your slightly stronger poison will neutralise your earlier inbibed one, but still kill the sneaky pharmacist. Ha ha. So you can never be too sure! Still a superb teaser, one of my top 3 definitely. mavericklotus Jun 06, 2002 A great teaser. Yet, I feel it needs to be made clear that the 'antidote' poison loses its deadly qualities as it neutralises the prior, weaker venom. I was hung up on the idea that to survive, one would need to continually consume stronger and stronger poison! odcsurferchick Jun 16, 2002 i thought that odcsurferchick Jun 16, 2002 i thought that 1 of them had killed the other and they all lived happyley ever after! Smart Jun 29, 2002 cool! doggyxp Jul 06, 2002 I like this riddle is good, but sortof copfusing. Jasin Jul 09, 2002 Excellent presentation.

Great explanation of the given facts. I was excited to see that the answer was exactly as I had guessed. I am rarely that close to the answer on a teaser that's so involved. Ember Oct 23, 2002 Very well writen and pretty difficult. ~~~nice job~~~ the_smart_one Nov 23, 2002 I love how you wrote this story. It was very good in the biggest font ever. GREAT JOB!!!!!! stonemug Dec 20, 2002 good one, I've seen this one on another site. deekdotcom Dec 20, 2002 Very well done Yanivster. I would have to say that this was the best teaser that i've ever read rajeshwar Jan 23, 2003 what a wonderful logic...... SourGir1986 Jan 29, 2003 That was great! lohki Mar 20, 2003 one word UBAH...very nice teaser..my fav so far hermdawg Apr 04, 2003 Awesome! whyme Apr 05, 2003 HEHEHEHEHEHEHEHEHE! gladiator1442 Apr 14, 2003 wow clever! desilu72 Apr 20, 2003 I figured out that there was water involved, but couldn't quite make the connection...well done. delendasd May 09, 2003 very nice indeed, job well done! adoontourious May 19, 2003 thats a good one, made me think about it like a good brain tease should tangerine May 23, 2003 Wow ... nice job!

But its a brilliant puzzle so that doesn't matter. ) xX_2_CuTe_Xx Jul 10, 2003 THIS ONE IS AWEOSME!! if there is/was an award for best riddle/puzzle this would have my vote!! jacintan Aug 09, 2003 This was very good, but at one point you called it a poison- not a potion. icehaven Aug 12, 2003 Quite confusing... kittycat663 Oct 16, 2003 way cool....... i thought for some reason the king would end up with nothing but i didn't realize how til' i read the answer. Really really really smart. kittycat663 Oct 16, 2003 i tihnk you mean to say they drank the POISON as planned. AXTON Jan 15, 2004 Fantastic teaser, easily the best i have read!!!! CONGRATULATIONS bbngk Jan 15, 2004 Great One CrystalScryer Feb 09, 2004 That was a very interesting and confusing one! I like it, it's 'cool'... MasterMind90 Feb 21, 2004 Very Clever! Iwould have never guessed! crystalstar Jun 25, 2004 Woaaaaaaaah, that was so awesome! Great! agenteasy Jun 29, 2004 Sorry guys, but this one doesn't work... The basic premise of the problem is that it takes a STRONG POISON to cancel a WEAK POISON. Therefore the treasurer's plan to bring water to the competition would have killed him (he would drink the water, and then drink the pharmacist's poison and then die from it). We can't say that water is the "weakest poison" because that would imply that anything is a weak poison, and therefore no poison could ever have effect (because it would be, by definition, always following a weaker poison... and therefore an antidote) Sorry.... Rashad Jul 22, 2004 What happened to the pharmacist after that knowing that he didn't do what the KING told him? twixy Jul 23, 2004 i liked this teaser. hot_chick Jul 28, 2004 WOW! excellent, quite long but worth the wait, keep it up! very good (user deleted) Aug 09, 2004 Outstanding teaser Chosh Nov 09, 2004 Brilliant. Absolutely Brilliant. Kdub Nov 15, 2004 I love it when a logic puzzle tests my logic like this one. Good teaser stormtrooper Feb 09, 2005 To the favorites! darthforman May 18, 2005 Sweet!

Nice teaser wandering_goat Oct 31, 2006 I love this one. I was determined to figure this out and finally, after wracking my brain over this for a while, I got it. eyenowhour Dec 18, 2006 Great job! I couldn't figure it out until I saw the answer. Very clever. adiga_on_line Jan 15, 2007 This is the most coolest teaser I've ever seen Good Job! brudork Mar 25, 2007 WOW!!... GREAT TEASER oddrey Jun 02, 2007 well written, fun, and i loved it. bfriedfischtom Apr 14, 2008 Great one. Andy1608 said: If the treasurer now realizes, that the pharmacist will also bring water? He the can switch back to poison and still win. But what if the pharmacist realizes that the treasurer realized that he realized ... and switch back to poison as well? Ad infinitum. What happens, if one drinks 3 poisons in a row, weak->strong->strongest. Will you survive? If yes, then there is a sure solution for the pharmacist: drink the weakest poison there is before and bring in the strongest there is to the king. If it is a toggle: no sure way .... cwjakesteel Nov 11, 2008 If they both brought water then how could either of them die? It said that the treasurer's poison was water so he couldn't have died from that poison which was the first one. javaguru Jan 03, 2009 While it was pretty easy to figure out, I liked this one because the answer was logically tight. Some of the teasers of this style have an arbitrary aspect. Very nice. Paladin Mar 16, 2009 Not sure why there is so much confusion over the answer... it is pretty plain and simply explained. The treasurer expected the pharmacist to make a strong poison, so the treasurer's plan was to drink water. Since a stronger poison neutralizes a weaker poison, the treasurer would drink a very weak poison ahead of time. Thus we would have the following: T0 = weak poison T1 = weak poison + pharmacist's poison = neutral T2 = neutralized poison + water P0 = nothing P1 = nothing + water P2 = water + pharmacist's posion Clearly the pharmacist would die. The pharmacist expected this plan and knew he would drink water from the treaurer then would be killed by his own poison, so he decided to bring water as well: T0 = weak poison T1 = weak poison + water T2 = weak poision + water + water P0 = nothing P1 = water P2 = water + water In this scenario, the treasurer would die, the pharmacist would live, and the king would have water thinking it was the strongest poison in the kingdom. This is a logic puzzle, and as such you have to take the premises as fact. It may not make logical sense that a strong poison could neutralize a weaker poison, but that is irrelevant in this case as it is an assumed fact. Very well done logic problem! bigmit37 Jul 08, 2009 This was very logical and I loved it. Couldn't solve it but I am happy with the answer. (user deleted) Feb 05, 2010 Solved it. Though, I'm not usually good at these, got lucky princess2007 Feb 23, 2013 I figured it out to the point that they'd both bring water. I just never got how the treasurer could survive. I guess I assumed that if he'd have anything before their "poison-drinking tournament", he'd die before the tournament started. Kinda arbitrary I guess. Good teaser! NoriMori Aug 05, 2014 I was very happy to see that this riddle is on here, because it is one of my very favourite riddles. rawbots Mar 18, 2016 This assumes two things: 1) The treasurer had no way to build a stronger poison than the pharmacist. 2) The treasurer wasn't going to bring poison for the pharmacist. If the treasurer tried to make poison (even if it was a weak poison), the pharmacist would have drunk it and then water, and would have died. This riddle gets 1 star.
