    Didnt watch the solution. Solution number one, if the barrerls take exactly 3 days to kill, then i would take 2 prisoners and drink from 15 wine barrels each every hour untill all 30 are done. Write down the hours and name the barrels. You got your poisoned barrel thanks to the hours.
    If that isnt what you wanted there is a 2nd solution,on the first day, give barrel 1,2,3,4,5,6 to prisoner 1; 7,8,9,0,11,12 to prisoner 2; 13,14,15,16,17,18 to prisoner 3; 19,20,21,22,23,24 to prisoner 4 and 25,26,27,28,29,30 to prisoner 5.
    On the second day, give barrel number 1,7,13,19,25 to prisoner 1; 2,8,14,20,26 to prisoner 2; 3,9,15,21,27 to prisoner 3; 4,10,16,22,28 to prisoner 4 and 5,11,17,23,29 to prisoner 5. Dont give barrels number 6,12,18,24,30 to anybody.
    Now, if prisoner 1 dies the first day and 2 dies the 2nd day, its barrel 2.
    If prisoner 4 fies the first day and 3 dies the 2nd day, its barrel 21. If only prisoner 3 dies and noone dies 2nd day, its 18. And so on.
    Note that the experiment will end by the 4th day's morning. Just in time for the feast.

    For those who don't want the complicated explanation, make all 5 drink from each wine barrel. Then in three days when some of them die, find the barrel that the ones that died all drank from. Or, capture the poisoner and torture him. Or throw the wine out and buy some new wine. I mean he's a king for pete's sake, you mean to tell me that he can't but more wine?

    Use rats. The poison would kill them much quicker. Probably within an hour. And there were plenty of rats during the time period that this riddle would have occurred in.

    I thought they drank 1, waited three days with the barrel next to them. If they was dead in three days with a barrel next to them, that one was POISONED.

  • MaidOfBoarDome
    MaidOfBoarDome 10 месяцев назад

    The solution was unnecessarily complicated. A better way to think about it would be to label the prisoners ABCDE. Barrel 1 is sampled by A only, 2 by B only, 3 by C only ... Barrel 6 is sampled by A and B, 7 is sampled by A and C, and so on.
    If you want to be somewhat humane, have no one sample one of the barrels, so that if no one dies, it's that barrel that's poisoned :)

    The video made it look more complicated than it was. Instead of identifying a barrell with a prisoner, you identify it with a specific subset of the prisoners, which lays way more possibilities. At the end of the three days you see which subset of prisoners dies, and here you have the revelation of the black sheep. This is not math just logic, and how some error detecting codes actually work in computers.

    I Have a better solution.
    Separate each prisoner with 6 barrels.When that one dies give two to two people and one to three people. If someone dies that had one barrel, you know which barrel it is. If it is someone with two barrels, give those two barrels to a prisoner that did survive and see which one dies. You then know which barrel is poisoned and the party will be great 👍🏻

  • Phil Kal

    If we make each prisoner drink 6 barrels but 1 but have a cup one hour after the previous one. For example prisoner 1 drinks at 14:00 barrel 13 and at 15:00 drinks barrel 14 and etc. After 3 days dies at 14:00. So it was barrel 13. I would like to ask if this is a wrong answer.

  • sulfuric acid
    sulfuric acid 11 месяцев назад

    my answer was since there are only five prisoners each prisoner takes a sip from six barrels at different time5 mins apart\and the riddle said they would die in EXACTLY 3 days meaning in 72 hours.So if prisoner one drank barrel no6 at 5:00 and he died at 5:00 3 days later barrel six is poisoned. or if prisoner 4 drank barrel no20 at 6:00 then died at 6 three days later then barrel 20 is poisoned and that was my solution.

    it is very simple:
    The Test/Tasting should be conducted on the 3rd Day.
    Besides on the 3rd day the Poison is already Fatal and even just a Tiny Portion of the Wine would be enough to KILL a man (as stated of the situation).
    The 5 Prisoners will be given 6 Barrels Each.
    Each Barrel should be tasted one by one by the prisoner (of their given Barrels).
    Then right away they will know which barrel was mixed with poison.
    so there's still 29 Barrels will be used in the Feast and 1 Prisoner will be dead.

    You could get the prisoners to take 1 sip of every piece of wine and get the king to watch it and after 3 days get to see who dies then get the alive prisoners to take a sip of the wine the dead prisoners then if any prisoners are alive still get them to try the ones that the alive prisoners tried yesterday then throw out the barrel which is poisoned because you can get the other prisoner to tell you which one is poisoned

  • John Randomness
    John Randomness Год назад

    My method was almost identical, but formulated differently. There are 32 possible subsets of the five prisoners. Ten pairs, ten triples, five singles, five foursomes, one empty set, and the complete set. Assign ten barrels to the ten pairs, ten more barrels to the ten triples, five barrels to the five singles, four barrels to four of the foursomes, and one barrel to the empty set. Again, which combo dies determines the poisoned barrel.

  • Amedeo
    Amedeo Год назад +9

    I thought of something else. Here's my theory: In the story, it's said that the poison needs EXACTLY 3 days to kill the person who took it. I would have given to each prisoner 6 barrels, as the total of barrels is 30 and the prisoners are 5, just how the story says. I would have labelled the prisoners with numbers from 1 to 5 and the barrels with numbers from 1 to 30, again, just how the story says. BUT i would have put the prisoners to drink from just one barrel every hour and everytime from a different barrel than the one they drank before. AND I WOULD HAVE KEPT EVIDENCE OF WHO DRANK FROM WHICH BARREL AT WHAT HOUR! If the poison has effect after EXACTLY three days, then, when one of the prisoners dies, I would just have to count back EXACTLY 72 hours and see from what barrel did the prisoner drink from. The secret to this theory is that the story says that they would die EXACTLY after 3 days. So I took advantage of this detail and put that pause of 1 hour between the drinks of the prisoners, so that I could count back 72 hours when one of the prisoners died and see what barrel he has drank from.

  • Dave Law
    Dave Law Год назад

    I think this is a much more logical, easier to follow answer (less mathy):
    1) Label all prisoners from 1-5
    2) Split up the barrels into 5 groups of 6, and label the barrels 1-6 for each group.
    3) Have the prisoner drink from the same barrel as their number. Ie prisoner 1 will drink from the 6 barrels labelled 1, prisoner 2 will drink from the 6 barrels labelled 2 etc. No one will drink from the barrel labelled 6 since there are only 5 prisoners.
    4) On the next day have each prisoner drink an entire group of barrels. So lets just label each group of 6 barrels A through E. So prisoner 1 will drink all 6 barrels from group A, prisoner 2 will drink from all 6 barrels from group B etc.
    5) Now we wait till the 3rd day and see who dies. If prisoner 1 dies, you know that 1 of the 5 barrels labelled 1 is poisoned. If NO ONE dies, you know that one of the 5 barrels labelled 6 must be poisoned since no one drank 6.
    6) Now we wait till the 4th day. We wait to see which prisoner dies. If, say, prisoner 3 dies then we know the poisoned barrel is from group C. And from the previous day we already know which numbered barrel it is.
    This answer assumes we are allowed to use the 4th day (assume the prisoner dies at the start of the 4th day, before the feast).

    The solution is confusing. I thought since they die in exactly 3 days you could have the prisoners try the wine in different orders. Then you narrow down the wine in the order of which the prisoners died.
