[@foxleo6729]

The question is sculpted to create comfortable imagery in what is the wrong direction (milk, rat). These are distractions in the question meant to allure you away from logic. It's a nice question but it's presented in an overly pacified manner for me. The answer is too obvious because of the lack of constants. There is only one constant, the amount of time it takes for the poison to take effect. Then one control, the amount of time you have to hypothetically use these resources to solve the problem. What is the most efficient way to recognize this, statement. This is the underlying purpose of logical deduction in complex ways but only two ways. This question is structured in an abductive nature but asks the reader to solve it using any logic they wish. All in all, its a nice entry level critical thinking problem.

[@SeanPat1001]

I would wait 3.5 hours. Saying that the poison would take affect in 10 hours is probably an average with some variation. Using an interval of 3.5 hours would reduce the risk due to the variation in the time until the poison takes effect. The third bottle would be administered at 10.5 hours, giving me a safety margin of 3.5 hours until 24 hours for the third bottle.

[@GokulRG]

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. You can also simply say I'll just feed a sample and look at symptoms after a few hours.. But this is not the real world, what's being tested is your logical thinking. 1 hr isn't arbitrary, that's the smallest unit of time here that can be measured.

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.

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.

I’m more concerned about drinking three bottles of warm milk that have been sitting around for 13 hours.

@@unclecreepy7025 The hour between times is just a safety buffer. In case the 'exactly' comment was less accurate than represented.

[@unclecreepy7025]

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.

[@sigmundjester]

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)

I would slam the first bottle on top of the rat. Which means that bottle had to be poisonous; since it killed the rat.

[@kibbledd1]

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.

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.

[@ChesuMori]

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.

[@Debbiebabe69]

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!

[@rashmimodi4744]

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

[@vijayraj7845]

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..

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

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."

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

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.

[@creepah_7]

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.

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

Ok before resuming the vid, I will assume the rat wouldn’t die from the poison.

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.

[@grahck4391]

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.
