Interview question for a Job in PETA would be like "You have 4 bottles out of which 3 are poisoned and you have to feed a cute rat. What would you do?"
It says 1 is poison.. 3 of them are milk.. 4 bottles total.... meaning one bottle is not of pure milk so it can not be a "bottle of milk" so if you drank 3 random and died you failed to drink 3 bottles of milk but instead 2 bottles of milk and a bottle of poisonous milk.... sooo.. your logic fails you!

Lol. you're just being asked to think logically here... No poison in the world is like an ON-OFF switch that'll exactly kill you in 10 hours while remaining without any symptoms till 9 hr 59 min.

I did the same solution, except with a bit more spacing (0, 5, and 10 hrs for feeding the first 3 samples). I know the problem says EXACTLY 10 hours but I'm a biochemist... and no poison is THAT exact. Spacing the samples out allows for more variability in the actual duration between dosing and death, and still gives plenty of time to identify the poisoned bottle.
DJ Rodgers idk how people thought this was hard. You could literally do them like 10 minutes apart which was my idea and save yourself the like 2 and a half hours
Hour 0 feed the rat bottle one Hour 1 feed the rat bottle two Hour 2 feed the rat bottle three Hour 3 feed the rat bottle four. You will have the answer when you time 10 hours after each feeding which will tell you the poisonous bottle. Mathematically you should have an answer in 13 hours. I’m more concerned about drinking three bottles of warm milk that have been sitting around for 13 hours.
Logically there’s no need for a safety buffer if the riddle tells you exactly 10 hours. And if you’re suppose to figure in a buffer, just test a bottle at the start (0 hr), 6.25 hr mark, and 13.5 hr mark. The 4th bottle doesn’t need to be tested because if the rat is alive after 23.5 hours, you know it’s the poisonous one. And you’ll have 30 minute buffer for the 3rd bottle and time to drink.
yeah, my timing was every 3 hours before I watched. Then I watched it and though... ohh dur, you could wait just 1 hour instead of 3. But then reading this, yeah 3 hours ensures better estimation guesses
My solution: The answer is in the riddle. It says one is poisoned. So you drink 2, 3, and 4 because 1 is poisoned. No need to test on the rat or wait 10+ hours.
@@lyzder7298 And with riddles, there is often a play on words or grammar. It would be perfectly acceptable to count "bottle one, bottle, two, bottle three, bottle four" or "one bottle, two bottle, three bottle, four bottle". Thus making "one bottle" equivalent to "bottle one". So when it is revealed that one is poisonous at the end, we already know that because the answer is in the question.
Feed the rat from 2 bottles to start--one feeding an hour earlier than the other. If nothing happens after 11hrs, then one of the two remaining bottles is poisoned. If the rat dies within 11hrs, one of the 1st two bottles is poisoned (and you can drink the other 2). Nothing happens: Feed the rat from 1 of the last 2 bottles. If it lives, the last remaining bottle is poisoned. If it dies, the bottle you just fed it from is poisoned. You now know which three are good to drink. The rat dies in the first try: You drink the other 2 bottles that haven't been tested, and--based on whether the rat dies at the 10hr or 11hr mark, you drink the opposite bottle from what killed the rat exactly 10hrs after it drank from it.
Claw4Grip Yeah he wasn’t *fully* optimized with his answer but hey it still works and at least it lets him have something to pay attention to while he’s locked in a chamber with milk and a rat :p
Feed him him all four bottles right away at hour interval's,mark time for each,hour ten, bottle one is poison, hour eleven, bottle two is poison, hour twelve,bottle three is poison, hour thirteen, bottle four is poison, you will have,12,13,or14 hours to relax and drink you're milk depending on you're marks!!! A little quicker!!!
Me: "Seems like you'd test the bottles an hour apart and note the time" Everyone in the comments: "Mix two bottles, and if the rat dies, you know it's one of those, so you can take your rat and bring it back from the dead and test again with it"
My answer before seeing the actual answer legit was "just drink any 3 bottles right before the 24 hours end. Even if you drank the poisonous milk, you've undeniably drunk 3 bottles of milk within 24 hours".
This channel:"it's a logic puzzle, you have to think logically!" Also this channel:"the poison will take effect at EXACTLY 10 hours, regardless of body composition or volume consumed. Also, it works exactly the same on a rat."
I think you are confusing logic with accuracy to the physical world. Two very different things. Something can be logical relative to certain definitions or axioms or assumptions which may or may not be true. That's why logicians talk about possible worlds so much. Take this for an example. Suppose Berlin is in Australia and Australia is in the US. It logically follows that Berlin is in the US. This is a valid conclusion despite all statements being wrong. It is perfectly logical but total BS at the same time ;-)
You think you're so cool, thinking of stuff that others haven't even considered. Get past it. Your logical ability looks even weaker than that of the maker of this "puzzle".
1) I agree, and appreciate, that the optimized solution is one where the rat has a 25% of living too! 2) That being said...rat metabolisms are different than ours...if this was IRL, I would probably leave 2 hours between each feeding, and feed it all four bottles, just in case. Still only takes 16 hours. 3) I'm so happy I (eventually) got this one, and I'm going to share it with my super-smart 6th graders to see if they can crack it too! :)
@IBHANAN M then u r asked to take 3 bottles within 24 hrs or u will die so if ur first 3 bottles have poison rat dies and u can't figure it out which one is poisonous and next u will also die😏😏
The problem is flawed, because it says you have to drink 3 bottles within 24 hours. Basically meaning that unless you consume a certain amount of milk in 24 hours then you will die. There is no fluid measurement specified other than the measure of “bottle”. For example if a bottle contains 500ml, then that means you have to consume 1500ml, not 1499ml. Similarly it means 3 bottles, not 2.99999 bottles. Since one of the bottles is poisoned and you can’t consume any of that, to fulfill the ‘rules’ of the problem you’d have to consume ALL the other bottles, but if you need to remove some for sampling then you are unable to consume 3 full bottles yourself. If this ‘rule’ can be broken, then you can simply let the rat try one bottle, and if it doesn’t die after 10 hours then you know that is fine, so pour two of the unopened bottles down the drain and divide the good milk into the 3 bottles and then drink it (what?! - it doesn’t specify FULL bottles)
Same... Then realised 6 hour delay is even better optimised, as poison won't be that precise and want to minimise overlap of error bars. Solution in video "wrong" because we wouldn't know how to interpret rat dying at 10:30.
My idea was to make a small mixture from bottles 1-2 and feed it to the rat. If after 10 hours it is fine, I know the first two bottles are safe, test a third, and then I can eliminate the poisoned bottle. Holes in my logic, but I gave myself 30 seconds and my tiny rat brain could only come up with that. Your solution is much better, well done:)
The only tricky thing about the problem is your brain immediately wants to think about how poison might actually take effect realistically, which could vary in time, so we feel as though we need to omit the given "fact" that it "ONLY takes effect AT 10 hours."
Answer can be these too : what if I test two bottles let's say 1st and 2th at starting , now if rat dies one of these two bottles is poisonous ( so I can drink 3rd and 4th) and I have still 14 hours to test which bottle is poisonous ( 1st or 2 nd). And if rat doesn't die when 1st and 2nd bottles are tested ( it means 1st and 2nd are non poisonous) and then you have enough time to test 3rd and 4th bottle
What if rat dies in testing the mixture of 1st and 2nd (u will have 3rd and 4th) but now u will not able to say in between 1st and 2nd which on js poisonous since the rat already dies.. (and u simply can't survive by having two bottles) And what will u do u have time, bt no rat for testing.. Ohhh poor rat ...😛
Give the rat a combo of 1&2. If it lives after 10 hrs you know both are good. Then give it bottle 3. If it dies then 3 is poison if it lives 4 is poison. If it dies after 1&2 you know one of them is poisonous. Feed it just 1. If it dies 1 is poison if it lives 2 is poison. That's how I did it.

Dear Sir , We like to offer you a job in Google as Google user , our deepest apology for missing out your job application. With Thanks, Google HR, Mr. Alex
With that solution, at the end you wouldn't have three complete bottles, as the rat would have drunk a little bit. So you'd have less than three bottles.
Another solution! Mix B1 and B2 then after 10 hrs you left with 2 choices ...either B1 has poison or B2 ......if not then B3 or B4 and in remaining 14 hr you have to test only 1 bottle
@@SnowBarry It doesn't work, becaus you need to drink three ENTIRE bottles. By doing this, You would only be able to safely drink the equivalent to two, thus dying from thirstiness.
@@NishantNaik2191 It doesn't work, because you need to drink three ENTIRE bottles. By doing this, You would only drink two, thus dying from thirstiness.
Just based on the puzzle as stated in the thumbnail, the solution seems pretty simple... assuming you you get a replacement rat if it dies from the poison. Start by feeding the rat samples of milk from two of the bottles. Ten hours later, if it shows signs of poisoning, you know it’s one of those two; otherwise, you know it’s one of the other two. You’re free to start drinking the two clean bottles, and can then feed the rat a sample from one of the remaining bottles. Whether it gets poisoned will tell you which bottle is the poison, and you have four hours to drink the other. If the poison does kill the rat, and you don’t get a replacement... well, that’s a different story. Guess I’ll actually watch the video now for the full conditions.
This question was amazingly easy when he mentioned it’d take exactly 10 hours… you could literally just feed the rat samples 10 minutes apart if you kept track of the time
Vengatesh Vengi you have only one rat In your first trial you killed the rat The second trail is not possible in a dead rat I also thought of this probability 😂
This doesn’t work, if one of the first two bottles is poisoned, the rat will die and you will not know which bottle killed it. This solutions requires chance, the correct solution does not.
Mix milk from 2 bottles and feed to mouse. If he doesn't die after 10 hours. It means those 2 bottles are not poisoned so you can drink milk from those 2 and now you have 14 hours remaining so you can check for remaining 1. If in starting case, if rat died then it means that remaining 2 bottles are not poisoned and now you can drink milk from those remaining bottle . And now again you have 14 hours remaining so you can check non poisoned bottle (which were selected at first)
@@dspyrofire9242 the poison doesn't dissappear. It's still there. the poison goes in to effect after 10 hours yes but if its still In the milk then it has nothing to react to (human body) it will be there until the milk has been drunk.
I thought of this: - Pour 2 bottles of milk in the first hour (since the poison takes effect after 10 hours). It'll have 50% chance that the poisoned bottle is there. The outcome: 1. If the rat dies when the time comes(0-10h), that means one of the bottle is the poisoned one. -Do the same thing, but take one bottle since you have 14h left. -In the next 4 hours you have time to drink other bottles :D 2. If the rat doesn't die, do the same thing for the bottles you didn't choose. but pour only one bottle.
Mix two samples of milk to test... it is actually very easy in fact got it immediately after reading the question.. Edit- I actually forgot that we have only one mouse so don't accuse me in the comment.. I was studying P&C before I attempted this so maybe... so sorry minna😊😊
One addendum I would make to the solution. If rat is alive after hour 10, begin drinking the first bottle then. Then repeat at the other hour intervals, provided the rat survives. If he dies, just skip that bottle and drink the others. This further optimizes the solution because the last part of the riddle is to drink three bottles of milk. Also, if someone is hungry, there's no way anyone would simply let a perfectly fine bottle of milk just sit there, especially if he knows it's safe after having tested it.
@@justnanta It satisfies hunger if it keeps you alive longer.. And milk isn't a carcinogen, so you would eventually die from lack of nutrition one way or another.
It seems impossible to me, because if by chance you give the rat any of the good milk you will have less than 3 bottles of good milk left, and you are required to drink 3 bottles of good milk within 24 hours.
Feed the rat the samples from each bottle with 1h intervals. If the rat dies 10h after consuming x sample, you know which one is poisoned. Proceed to drink the other 3 bottles

Easy-Peasy I solved it!!! I've got an idea give 1 sample to the rat if the rat did not die after 10 hours that bottle is safe, give two samples having a gap of hour to the rat if he doesn't die then consume these two milk bottle and if he dies then if the rat dies at the 20th hour don't drink the bottle given first and if he dies at 21th hour just drink the earlier given bottle at last drink the last bottle Hence the three bottles will be consumed 3 hours before the deadline.
You must consume 3 bottles of milk, and one is poisoned? The ONLY way to do this is to guess randomly. Because as soon as you extract a sample from any bottle, it it no longer a full bottle and would contribute less than 1 to the needed 3.
@@israelRaizer You cannot ass-u-me anything in a math problem. The criteria is explicitly stated, and inviolate. Or, in this case, horrendously badly stated. But the rules stay the same. If you "assume" you are allowed to use reduce each bottle by a sample size.. Why not "assume" that you can make that sample size 1/1 th of the bottle? And tus repeatedly drink a full bottle from the same bottle.
@@marvinkitfox3386 or maybe each bottle comes with a separate sample, but there's another problem with this... It says the poison takes effect "at 10h" instead of "in 10h"
Ok before resuming the vid, I will assume the rat wouldn’t die from the poison. Gonna do 2 bottles first then try one last. *Edit*: ok so I was hoping since it wasn’t said in the first place but the rat actually dies. I came up with this before I got the chance to think about doing tests per hour. (Again, I assumed the rat only shows weakness) First, I will test bottles one and two together. If said rat gets sick, then i would test bottle one. If it gets sick again, avoid said bottle. If the rat ‘survives’, avoid the untested bottle. If the rat doesn’t get sick after testing both bottles, test bottle 3. If the rat gets sick, avoid said bottle. If not, avoid the untested one. If each test was done for 10 hours each, I will still have 4 hours left to spare worst case scenario.
Can this be a solution ? Here I feed from 2 bottle to the rat after 10 hrs if rat dies we know its from that two bottle if not its from next two after that feeding 1 bottle from next 2 bottle and we can find out the poisonous bottle
@@akshatgupta5752 2 bottles don't work too. Scenario 1: Give samples of 2 bottles to the rat and it dies after 10 hours. Now how would you figure out which bottle is poisonous with a dead rat?

The only solution that works is testing the bottles one by one.
@@VR471 You make a point on scenario 1. In the second case where rat does not die, you know bottles 3&4 are safe. Then you can feed either of the bottles 1or 2. Problem Solved! I cannot argue on the 1st scenario
@@gitashrimaity9501 Oh yeah, if the rat does survive the first scenario, then it's either bottle 3 or 4 that's poisoned. That's true. But surviving the first one is a very big uncertainty.
Combinations do work though. Say you have bottle 1, 2, 3 and 4. First you give the rat a sample of 1 and 2. If the rat dies after 10hrs, either 1 or 2 is poisonous. If not, either 3 or 4 is poisonous. Say it dies: 1 or 2 is poisonous. Give the rat a sample from bottle 1. If it dies after 10hrs (in total 20), 1 is poisonous, if not, then 2 is. If the rat didn't die after the first 10hrs, you give it sample 3. If it dies, 3 is poisonous, if not, it's 4.
There is a comment like this above.. Consider: I give sample 1 and 2 to the rat. After 10 hours, it dies. *The rat is dead* Since the rat is dead, now I have no way to test whether bottle 1 or bottle 2 is poisonous.

@@pohontauge4551 yea but in a safe way? Because you add poison to blood and not other way round and to have 4 tests of it you need to sufficient amount of blood with the hope that you'll close the wound as well.

No need to wait until hour 13, if the rat lives past hour 12 you know it's bottle four anyways.

@@unclecreepy7025 The hour between times is just a safety buffer. In case the 'exactly' comment was less accurate than represented.
Logically there’s no need for a safety buffer if the riddle tells you exactly 10 hours. And if you’re suppose to figure in a buffer, just test a bottle at the start (0 hr), 6.25 hr mark, and 13.5 hr mark. The 4th bottle doesn’t need to be tested because if the rat is alive after 23.5 hours, you know it’s the poisonous one. And you’ll have 30 minute buffer for the 3rd bottle and time to drink.

There is a label underneath the bottle saying poisonous. Wtf google
Alexa, which bottle is poisonous?
- you start monday!
Great idea mathematically, in reality though if that rat dies in 10.5 hours you’re screwed

1st bottle at 0 hr

yeah, my timing was every 3 hours before I watched. Then I watched it and though... ohh dur, you could wait just 1 hour instead of 3. But then reading this, yeah 3 hours ensures better estimation guesses
My solution:
The answer is in the riddle. It says one is poisoned. So you drink 2, 3, and 4 because 1 is poisoned. No need to test on the rat or wait 10+ hours.

And with riddles, there is often a play on words or grammar. It would be perfectly acceptable to count "bottle one, bottle, two, bottle three, bottle four" or "one bottle, two bottle, three bottle, four bottle". Thus making "one bottle" equivalent to "bottle one". So when it is revealed that one is poisonous at the end, we already know that because the answer is in the question.
@@lyzder7298 then there are autists like me who would just go "just don't drink the bottle itself, but the milk"
Nah, it says 'one BOTTLE' not 'one'.
Harvard: Do you want a scholarship?
Feed the rat from 2 bottles to start--one feeding an hour earlier than the other. If nothing happens after 11hrs, then one of the two remaining bottles is poisoned. If the rat dies within 11hrs, one of the 1st two bottles is poisoned (and you can drink the other 2).
Nothing happens: Feed the rat from 1 of the last 2 bottles. If it lives, the last remaining bottle is poisoned. If it dies, the bottle you just fed it from is poisoned. You now know which three are good to drink.
The rat dies in the first try: You drink the other 2 bottles that haven't been tested, and--based on whether the rat dies at the 10hr or 11hr mark, you drink the opposite bottle from what killed the rat exactly 10hrs after it drank from it.
That's exactly what I was thinking too!
Daniel Kilby Yeah that’s what I was thinking as well.
One flaw: if nothing happens, then you have wait another 10 hours which is not efficient.
Claw4Grip Yeah he wasn’t *fully* optimized with his answer but hey it still works and at least it lets him have something to pay attention to while he’s locked in a chamber with milk and a rat :p
Feed him him all four bottles right away at hour interval's,mark time for each,hour ten, bottle one is poison, hour eleven, bottle two is poison, hour twelve,bottle three is poison, hour thirteen, bottle four is poison, you will have,12,13,or14 hours to relax and drink you're milk depending on you're marks!!!

This channel:"it's a logic puzzle, you have to think logically!"
Also this channel:"the poison will take effect at EXACTLY 10 hours, regardless of body composition or volume consumed. Also, it works exactly the same on a rat."
Honest
I think you are confusing logic with accuracy to the physical world. Two very different things. Something can be logical relative to certain definitions or axioms or assumptions which may or may not be true. That's why logicians talk about possible worlds so much. Take this for an example.
Suppose Berlin is in Australia and Australia is in the US. It logically follows that Berlin is in the US. This is a valid conclusion despite all statements being wrong. It is perfectly logical but total BS at the same time ;-)
Someone doesn't know what logic actually is
You think you're so cool, thinking of stuff that others haven't even considered. Get past it. Your logical ability looks even weaker than that of the maker of this "puzzle".
It doesn't claim to take 10 hours on a human, just the rat. It may be that it would take 10 hours considering the composition of the rat in question
Google: What strategy would ensure you drink 3 bottles of milk within 24 hours?
Me, an intellectual: Just drink 3 bottles at random within 10 hours.
Drink them all when there's 9 hrs left
Brigham richins that was my first thought. I would’ve asked, “do you need to stay alive?”
1) I agree, and appreciate, that the optimized solution is one where the rat has a 25% of living too!
2) That being said...rat metabolisms are different than ours...if this was IRL, I would probably leave 2 hours between each feeding, and feed it all four bottles, just in case. Still only takes 16 hours.
3) I'm so happy I (eventually) got this one, and I'm going to share it with my super-smart 6th graders to see if they can crack it too! :)

Lol what if u misswd to observe the rat at the time of its last breath
In very optimized short time
The problem is flawed, because it says you have to drink 3 bottles within 24 hours. Basically meaning that unless you consume a certain amount of milk in 24 hours then you will die. There is no fluid measurement specified other than the measure of “bottle”. For example if a bottle contains 500ml, then that means you have to consume 1500ml, not 1499ml. Similarly it means 3 bottles, not 2.99999 bottles. Since one of the bottles is poisoned and you can’t consume any of that, to fulfill the ‘rules’ of the problem you’d have to consume ALL the other bottles, but if you need to remove some for sampling then you are unable to consume 3 full bottles yourself.
If this ‘rule’ can be broken, then you can simply let the rat try one bottle, and if it doesn’t die after 10 hours then you know that is fine, so pour two of the unopened bottles down the drain and divide the good milk into the 3 bottles and then drink it (what?! - it doesn’t specify FULL bottles)
The real question is why is the milk yellow? Or are you even drinking milk?

My idea was to make a small mixture from bottles 1-2 and feed it to the rat.

@@JohnAndrew6549u don't need the other combo. U need one of the bottles from the first combo
The only tricky thing about the problem is your brain immediately wants to think about how poison might actually take effect realistically, which could vary in time, so we feel as though we need to omit the given "fact" that it "ONLY takes effect AT 10 hours."
Answer can be these too : what if I test two bottles let's say 1st and 2th at starting , now if rat dies one of these two bottles is poisonous ( so I can drink 3rd and 4th) and I have still 14 hours to test which bottle is poisonous ( 1st or 2 nd). And if rat doesn't die when 1st and 2nd bottles are tested ( it means 1st and 2nd are non poisonous) and then you have enough time to test 3rd and 4th bottle
What if rat dies in testing the mixture of 1st and 2nd (u will have 3rd and 4th) but now u will not able to say in between 1st and 2nd which on js poisonous since the rat already dies.. (and u simply can't survive by having two bottles)
And what will u do u have time, bt no rat for testing..

Just based on the puzzle as stated in the thumbnail, the solution seems pretty simple... assuming you you get a replacement rat if it dies from the poison. Start by feeding the rat samples of milk from two of the bottles. Ten hours later, if it shows signs of poisoning, you know it’s one of those two; otherwise, you know it’s one of the other two. You’re free to start drinking the two clean bottles, and can then feed the rat a sample from one of the remaining bottles. Whether it gets poisoned will tell you which bottle is the poison, and you have four hours to drink the other.
If the poison does kill the rat, and you don’t get a replacement... well, that’s a different story. Guess I’ll actually watch the video now for the full conditions.
Pretty sure you only get one rat....
If the poison kills the rat though, you know which bottle is venomous, so you have already won!
It's the same solution that first came to my mind! But it says you only have one rat :'(
I also thought exact same thing ..but shortage of rat make this plan failed😅😅

This question was amazingly easy when he mentioned it’d take exactly 10 hours…

Agreed. It becomes much more interesting when you try to optimize for potential margin of error on the 10 hr poison and on you dying at exactly 24 hrs

This doesn’t work, if one of the first two bottles is poisoned, the rat will die and you will not know which bottle killed it. This solutions requires chance, the correct solution does not.

Mix milk from 2 bottles and feed to mouse. If he doesn't die after 10 hours. It means those 2 bottles are not poisoned so you can drink milk from those 2 and now you have 14 hours remaining so you can check for remaining 1.
If in starting case, if rat died then it means that remaining 2 bottles are not poisoned and now you can drink milk from those remaining bottle .

One addendum I would make to the solution. If rat is alive after hour 10, begin drinking the first bottle then. Then repeat at the other hour intervals, provided the rat survives. If he dies, just skip that bottle and drink the others. This further optimizes the solution because the last part of the riddle is to drink three bottles of milk. Also, if someone is hungry, there's no way anyone would simply let a perfectly fine bottle of milk just sit there, especially if he knows it's safe after having tested it.

Hence the three bottles will be consumed 3 hours before the deadline.
You must consume 3 bottles of milk, and one is poisoned?
The ONLY way to do this is to guess randomly.
Because as soon as you extract a sample from any bottle, it it no longer a full bottle and would contribute less than 1 to the needed 3.

I came up with this before I got the chance to think about doing tests per hour. (Again, I assumed the rat only shows weakness)
First, I will test bottles one and two together. If said rat gets sick, then i would test bottle one. If it gets sick again, avoid said bottle. If the rat ‘survives’, avoid the untested bottle.
If the rat doesn’t get sick after testing both bottles, test bottle 3. If the rat gets sick, avoid said bottle. If not, avoid the untested one.

Combinations do work though. Say you have bottle 1, 2, 3 and 4.

Give the rat a sample from bottle 1. If it dies after 10hrs (in total 20), 1 is poisonous, if not, then 2 is.
If the rat didn't die after the first 10hrs, you give it sample 3. If it dies, 3 is poisonous, if not, it's 4.

now we will feed any of one bottle that were selected in first
after 14 hours if rat does die than we will not drink that
if not then we can
afterall we still have 4 hours
its the right method...
