I watched the video to see what part of the description I misinterpreted to make this tricky There wasnt, it was super simple
Comment from : Tiemen

Hey google this puzzle is trivial please give me your faang salary
Comment from : Robert

Seems too trivial Feed a sample every hour to the rat Look when he dies Deduce which sample poisoned him You could only feed it 3 samples and, with luck, spare its lifebr(Watched the video : well, duh)
Comment from : Youri Khan

is the milk pateurized? refrigerated?
Comment from : itchynackers

twistthe rat dies of a heart attack at 10 hours from eating so much cheese you mistakenly assume that milk was poisoned, and drink the rest
Comment from : itchynackers

This must be the easiest Google interview question I solved it in 10 seconds And solving this puzzle doesn't really demonstrate anything

Haven't watched video yet But a rather obvious solution comes to mindbr1 Feed rat sample from bottle 1br2 Wait an hourbr3 Feed rat sample from bottle 2br4 Wait an hourbr5 Feed rat sample from bottle 3br6 (optional) Wait an hourbr7 (optional) Feed rat sample from bottle 4brNow wait until rat dies If rat dies at hour 10, bottle 1 is poison; 11 bottle 2 is poison; 12 bottle 3 is poison; 13 bottle 4 is poisonbrbrNow, if I have 2 or more ratsbr1 Feed rat sample from bottles 1&2br2 Wait 10 hours If rat is dead, poison is in either bottle 1 or 2, feed sample from bottle 1 to rat and wait another 10 hoursbretc
Comment from : John Cochran

LD on rsts is different compared to human, and poison on rats reacts like 3x faster compared to human So it's hard to tell if your technique will work or not
Comment from : World Class Mind

Inject all 4 into my blood and sell the rat, they are poison, not venom
Comment from : Sans15

feed a sample from bottle 1 wait an hour feed bottle two wait an hour feed bottle 3 wait till 10 hours see if rat dies 11 hours see if rat dies, 12 hours see if rat dies
Comment from : Ritchie Dee

What if the rat refuse to drink?
Comment from : Digbijoy Roy

The puzzle should set a limit of 14h instead
Comment from : Leo Jose

Brilliant ! Many thanks 😊👍
Comment from : peppermann

Felt like i was misunderstanding the question because this question seemed trivial
Comment from : Adrian Avalo

Feed those bottles to those employess They will never give such problems to anyone 😂
Comment from : Online School

So freaking easy
Comment from : Mansi Barewar

I got the answer, I just left 5 hours between each testing just in case it gets done safely within 20 hours
Comment from : gul

Eat the rat
Comment from : drdassler

I split it up into 4 time tables Same idea but you wouldn't know until hour 22 instead of hour 12 first bottle hour 0 second bottle hour 6 third bottle hour 12 fourth bottle hour 18 (fourth bottle is irrelevant because hour 22 will reveal if rat is dead from bottle 3 or not)
Comment from : Mark Tate

Guess I'm dead because I'm lactose intolerant
Comment from : Theo Boangiu

Now what i will drink 😢 i will die due to hunger
Comment from : galib ki yaadein

Don't drink yellow milk
Comment from : 420th Legioner

I got the solution but I was thinking why the time limit is 24 hours Seems like there's a lot of time left after the testing
Comment from : Sadaharu

withing 2 seconds i solve this puzzle and ia m proud myself!!!
Comment from : farukh shaikh

Feed the rat 3 bottles If it dies, the fourth is for sure safe If it doesn’t die, the fourth is the poisen and you can drink any of the three
Comment from : MarshyGamer

If the milk is that color you shouldn't drink any of them
Comment from : Paul Foley

My first guess: give a sample of bottle 1 at the start Sample of bottle 2 at 30 minutes, and two more samples separating those Use the timer to see which bottle causes the poison The 30 minute timer can be tweaked, of coursebrbrEdit: iYeah/i your solution does it with 1 hour and also omits checking bottle 4
Comment from : Paul-Stelian Olaru

Way to easy for google
Comment from : Schawid Dulze

It is easy if the poison affects the rat at exactly 10 hours, but if it is within 10 hours, you cannot know which is the poisonous bottle with this solution
Comment from : Mehmet Yeşilyurt

I worked out that you could 'overlap' the doses of milk but I had a 5 hour gap between dosesbr1 hour is probably a bit too close together to be 100 sure which one poisoned the ratbrSo brGive the 1st dose to the rat and if it dies at 10 hrs it was that bottlebrgive the 2nd dose at 5 hrs and if it dies at 15 hrs it was that bottlebrgive the 3rd dose at 10 hrs and if it dies at 20 hrs it was that bottlebrand if the rat is still alive at 20 hrs you know that 4th bottle is poisoned
Comment from : MrMousley

What if the rat is fatally allergic to lactose?
Comment from : answer base

I solved it by myself
Comment from : Ibne Batuta

Rat 🐀saved by the answerbut 3 bottle is empty 😕wat about manhe as to drink within in 24 hours 🤔😅I think so google answer was wrong bcz the 3 bottle was without poison but u reduced the level of milk how man can survive
Comment from : Michael Raj

Thank you @rownak for the wonderful question
Comment from : Bhavesh Buzz

Easy
Comment from : Andrés Hevia Heredia

GhantaBiologically not possibleRats don't have separate stomach and body system for each bottle
Comment from : DINESH BANSIWAL

In my head I was feeding the rat every two hours a sample from a new bottle and I had about 6 hours left to decide which bottle was laced with poison ☠️brGood riddle I actually like this one!
Comment from : Buddric

This makes little sense No poison kills bexactly/b after 10 hours
Comment from : Teo Martini

We can give each bottle at a particular gap say 1 hour When rat dies, we can assure that milk given exactly 10 hr ago is poisonous
Comment from : Tushar Jain

0:26 But how can I consume 3 bottles of milk if I am giving the rat samples of each? Sounds like I will die regardless whether by drinking poison or not drinking all the bottles of milk because they aren't full anymore
Comment from : TommonSensePro

I initially thought of feeding the rat 2 at a time, but thats basically the same thing
Comment from : LRR Matrix

After having fed the bottles to the rat i dont have any milk left so I wont be able to drink it anyway
Comment from : Pulpo CH

I can think of many people I would like to test these bottles on
Comment from : 99guspuppet

And it dies after the first non poisonous bottle due to severe lactose intolerance which we aren’t aware of, as it’s a hidden term and condition that you sign on the forms when you go for your interview… 😁 the previous ‘might’ not actually be true
Comment from : El Dante

Maybe just a little outside the box thinkingbrJust wait it outbrI'm pretty sure I can survive 24hrs without drinking 3 bottles of milk!! 🤪🤪
Comment from : Bryan Kautz

If that's all it takes to get a job at google
Comment from : Graham Heath

unfortunately you can't survive this scenario with this strategy as the rat has sampled some of the milk, now you don't have 3 whole bottles of milk to consume, so you die!
Comment from : Craig Wyatt

If you are trapped in a room feed the rat the 4th bottle anyway to kill it You don't wanna be trapped in a room with a living rat Also, you will find out if the 4th bottle really is poisoned and if the 10 hours part is correct
Comment from : Tiago Kang

Easy, just drink any three The rules don't state you have to survive
Comment from : Ujaash Roy Chowdhury Roy Chowdhury

Those who are in doubt now Google don't ask puzzle for freshers 🤣
Comment from : Sandeep Sharma

too easyyyyyyyyyy
Comment from : Ayush Agarwal 4-Year BTech Electronics Engineering

If this is a google interview question no wonder people work at Apple and Samsung, such a question doesn’t take into account the person
Comment from : Robin Pegden

In the spirit that you normally employ to trick viewers in your videos, just drink three bottles, any three The problem didn't say you had to drink unpoisoned ones Solved
Comment from : jonahansen

Got it straight away - pretty simple
Comment from : mastergx1

Eat the rat Hunger gone
Comment from : FFM0594

I thought of this
Comment from : LW Paradis

One cannot drink three (3) bottles, for one has given a portion of milk to a rat
Comment from : M V

This must be a damn punctual poison I would test the bottles at longer intervals, maybe 2-4 hours No poison on earth kills or shows symptoms at iexactly/i ten hours That's why the expected time for onset of symptoms is usually expressed with a window of time, like 2-4 hours, 8-12 hours, 20- 60 minutes, etc
Comment from : Michael Driggers

I came up with a different solution, feed 1 and 2 to rat, if fine on 10th hour feed just 1 of 3 or 4 If live 3 it's 4 if not it's 3 If not fine on 1 and 2, feed just one of them, by feeding say 1 and fine must be 2, vice versa By the 20th hour you have the solution to consume the bottles before 24h
Comment from : Light Lord

Just escape the room quickly and quickly go to a restaurant
Comment from : Ayden HK

I hope it was question for "cleaning" position? Because IT requires absolutely different criteria
Comment from : Daite Dve

No-one said that the poison would kill me I would drink all 4 and not die😁
Comment from : Preggie Nair

I solved this in 4 min 😅
Comment from : Headshot 😒

But Ammar, what if I am lactose intolerant and can't drink milk? BTW, the answer to this one was easy
Comment from : R Brown

What is the point of taking 1 hr gap we can feed the rat in short intervals(as short as 5min) and check if rat dies after 10hr or 10hr5min or 10hr10min
Comment from : Hemalatha M

Test the milk on rat after every 2-3 hours
Comment from : Anuradha Thakur

I have lactose intolerance, the poison might be a better option
Comment from : Jeremy Stangel

Feed the first two at the same time, if rat dies, drink the other two and take the 50/50 chance
Comment from : Vairoon

Too easy I would rather compose an escape plan with the rat and poison my kidnappers with the poisoned milk
Comment from : Gazorpa Zorp

Just now finding this video so here’s what I think:brYou are given those three bottles to sate your thirst, the 24 hour period is the time before you die if you do not drink anything Test bottle 1 - if after 10 hours it is safe, drink that bottle Repeat until you find the poisoned bottle
