Luca MaciМесяц назадI've solved it in a different way which i prefer more, but i'm lazy and anyway noone is gonna read this :/

If anyone is interested let me know, i think you'll like this solution.

My Thinking About Science and Maths3 месяца назад^{+1}Tell why this trick worked

EvaChan Yanling8 месяцев назадIt was barrel 18 got poisoned

Disha Bhattacharya8 месяцев назад^{+1}Direct answer:- Don't give us a headache!!! Just throw them all and buy new barrels of wine! You are a king! You have lots of money!! I just wasted my time on here!!! Anyway other riddles you uploaded are good.

kawaillgirl roblox and more10 месяцев назадWhat is the music

Johaylon11 месяцев назадDidnt 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.

Johaylon11 месяцев назадThe solution is even better... incredible.

YoshiГод назадMade by albert einstein

PeopleTechnologyTricksГод назадI thhought the same as you but at this age they didnt had clocks that were si accurate as today and those numbers invented years later for the purpose of programming computers

Rachel HunterГод назадI can usually manage riddles okay, but once you start using maths (beyond the basics, I mean); my mind is totally screwed, LOL. Maths was always my worst subject at school, apart from PE. I have no problems with English as a subject, though... 😅

HeWhoChoosesГод назадFor 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?

HeWhoChoosesГод назадUse 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.

UrlaГод назадSush anjay

Maddie vs LaceyГод назадI 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.

MaidOfBoarDomeГод назадThe 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 :)

John BrownfieldГод назадWelp I got fucking wrecked on this one. Pretty sure even mathematicians wouldn't be like " Oh that's easy! Just use binary math!! Simple."

Joseph ClausonГод назадthere is a much simpler way!!!! just give them the different barrels of wine at different times of the day. mark them as such and in three days time the prisoner will die at the exact time in which they drank it allowing them to find out which one was poisined

Sunetra SГод назадI CAN'T ABLE TO UNDERSTAND ANYTHING.GOD HELP ME PLEASE.BRAIN COOL YOU MADE ME BRAIN HOT .WAS GOING TO SLEEP AND NOW I CAN'T.IT WILL BECOME MESS IF WE SLOVE THE PUZZLE WITH BINARY METHOD. ☹😳😩

ashley mingsГод назадI didn't understand a thing

Candric ChengГод назад^{+1}just wonder if one or two prisoners have liver cancer and died not coz of the poison but coz that he / they drink too many wines that their doctor wont suggest, and confusing the true poisoned barrel with an innocent one.

RyuuzakiXIIIГод назадThe 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.

Michael BA77Год назад^{+3}or cancel the feast :D

Marlen CuchilloГод назадyou can wait till the 3 day then drink it

CoopDog 101Год назад^{+3}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 KalГод назадIf 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.

KdM _Год назадBinary didn't exist when medival kings were around.... Disliked

SertefaГод назадyesss I'm a genius u cross the tests so that you can understand which is the poisoned barrel by the death of those who both tried it

Anti-Thot AdministrationГод назадmy 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.

Gloria RangelГод назадi didnt like the math part

Jack OliverГод назадToday my friend David lost his ID. Now we just call him Dav... 😂😂

Junren LiГод назад2/3 :)

KairoReactГод назадit 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.

Nate KovoГод назадdid anyone figure out the riddle as they described it.And did anyone understand there crazy solution

Paulinka GГод назад^{+1}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

Miguel MoriceГод назадI'm 11 and I'm supposed to know this shit

XZAVideosFun existГод назадthe prisonser added Poison too the wine for the king

Smid 429Год назадeach inmate tests 6 if one of them dies you know poison is in one of those.with the immates left test foue wines if one dies we know whe*e is the poison, if no one dies test 2 ba**els one dies and you know whe*e is the poison.(the lette* next to "e" not wo*king)

Pilgrim AJГод назадUm...throw them out and buy wine from a neighboring country?

Tatar BoyГод назадGot correct

Patchy PadillaГод назадmaybe they should give each prison one cup of wine each barrel. 1 drop can kill you in 3 days so, maybe the prison who takes a poisonous wine will die immediately😂✌✌✌

X hard rockerГод назадabsolutely amazing riddle, love it

ρrø gσdГод назад^{+1}well it was very easy question anyone should know this question

Jack SandbladhГод назадum ok The wine question its an eayser way

ATHARVA SUBHEDARГод назадwe would ask just one prisoner to drink one drop each day daily...suppose he dies on 5 january then previous 3 days that is 2 january.The bottle that he drank on 2 jan contains the poison

ATHARVA SUBHEDARГод назадBut if it was many days..this would work

ATHARVA SUBHEDARГод назадsorry i didnt notice the 4 days period

John RandomnessГод назадMy 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.

EmeraldGamingГод назадGEEZ I came for a little brain trick and fun!!!! My brain hurts q-q T-T

Minecraft 101Год назадI didn't understand any of this and found a much simpler solution. You could get 25 more people to have some and remember who had which one. Then see who's dead

GD RixtyIsMyCityГод назадat the start he clearly poisoned barrel 6 or 7

satan YtГод назадhow dare tou bring math in this

RoZaurus?Год назадNO WAY I GOT THIS CORRECT 😮

RVHoboГод назад^{+1}To easy, He is the King, just order his people to bring him more wine, duh.

Element GamingГод назадI'VE GONE TO FAR INTO THE INTERNET... help

Eugene Augusta WijayaГод назадwhy not just test all 6 and if one died take those barrels and ask the prisoners 4 of them to test any 4/6 of them thwres a high chance a person dies so u take that barrel away

The Arkham KnightГод назадIt doesnt say that the guards caught the traitor that doesnt mean that the guards said they didnt caught the traitor means they did catch him the king could ask the traitor that which barrel is poisoned if he doesnt tell him then they should torcher him and then make him speak like if you understand the idea

ourWorld LucyГод назадIf they didn't catch him, he ran away! How would they question him??

Scorpion The Netherrealm SpectereГод назадOMG just make the guy drink a Lil bit of each barrel and then get enough wine to refill stop trying to make this hard

ourWorld LucyГод назадIf they could do that, this riddle would not exist...

SouthBeastGaming FTWГод назад^{+2}Would it be exact second intervals? If so, you could do it like this.

Assign 6 barrels to 5 prisoners

P1-1,2,3,4,5,6

ctn

P6-25,26,27.28,29,30

Drink the first one at 12 o'clock afternoon

Drink the second one at 12:01, etc.

Three days later, examine the prisoners.

If prisoner #1 died at 12:03, it would be barrel number #3

ourWorld LucyГод назадBut it takes 3 days to kill no matter how much you take.

ATAUR RAHMANГод назадI saw all this riddles in eg mines

jungSHOOKtГод назад187th!

Srinivasan SivakumarГод назад^{+5}Im pretty sure binary method didnt exist then

Ethopian ScientistГод назадor just let one drink 6 each and when one dies the rest will drink from the 5 remaining if 1 dies then we know which one is poisoned if none dies the we know to one remainder is poisoned .

Marinel RamosГод назадourWorld Lucy i agree

ourWorld LucyГод назад^{+1}That doesn't help, if one drinks from 6 how can you check the other 24?! Remember it takes 3 days to kill them

ExtremeGamer992Год назадBut if it was the medieval times, computers did not exist so that means binary did not exist

AmedeoГод назад^{+10}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.

ourWorld LucyГод назадNice, that is a way to go

saurabh kushwahaГод назадexcellent....👌👌

Autistic FierГод назадCan the king drink water instead? Water is the best man just drink water

Dave LawГод назадI 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).

DaTheorizerГод назадMy answer

THROW ALL THE WINE AWAY! GET ROOTBEER INSTEAD

blackmail boiГод назад^{+5}Solution: WE NEED MORE PRISONERS!!!!

burnyan a random fanГод назадTommy Watterson lol true

Rabiya Darvesh DarveshГод назадThis is sooo confusing i cant understand anything

dragonslayer015Год назадThe 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.

ThatIrrelevantAsian __Год назадAaaahhh god my eyes ! ALL THE TYPOS

jajo banГод назадbetter they can give the wine to the person who mixed the poison in it

grassrootsГод назадfor the poisoning one, didnt one prisoner already die?

roblox gamertvГод назадeh

Shree Vivek CompusoftГод назадWAIT FOR 3 DAYS AS THE POISON BECOMES FATAL AFTER 3 DAYS

do the same thing tell the prisoners to drink from every barrel then wait so suppose barrel NO.5 was poisoned then the prisoner who will drink from it will die instantly and we will know that 5 was poisoned

Shree Vivek CompusoftГод назадBorat Sagdiyev you understand it wrong we would do it like he said each prisoner have 6 barrels to drink tell them to drink one barrel and wait for some time so suppose 5 no. was poisoned no1 prisoner would die instantly after that 5 is poisioned

Borat SagdiyevГод назадIf every prisoner dies and all of them drank every barrel, how would you know what barrel was poisoned?

Ruttun CiaraГод назадIn all its not good to test poison wine on prisoners.😣😢

Neelu SharmaГод назад^{+3}This is the best riddle I have ever seen

alan serjuseГод назадthe technique was cool.. but prob is that it's possible only up to 32 barrels.. what if there were 33 barrels? you will then need 6 prisoners.. still, it was a nice one.. u should make more videos👌👍👍
