Can you solve the rebel supplies riddle? - Alex Gendler

Practice more problem-solving at brilliant.org/TedEd/
Solution to Bonus Riddle: brilliant.org/tededmislabelle...
You’re overseeing the delivery of supplies to a rebel base in the heart of enemy territory. To get past customs, all packages must follow this rule: if a box is marked with an even number on the bottom, it must be sealed with a red top. One of the four boxes was sealed incorrectly, but they lost track of which one. Can you figure out which box it is and save the day? Alex Gendler shows how.

The riddle is slightly confusing especially the part where they say that when we grab a box, we would deprived the rebels of their supplies. So I thought you can only inspect 1 box to make sure that is the wrong one. Not taking two boxes away.

for the bonus riddle you only have to open 2 boxes: open any one and if it's right, easy. if not, open the box labelled with what you found. the box labelled with what you find in the second box is also wrong, so the final box is correct example: i open the apples box and find dates, then open the dates box. it can't contain dates since the apples box does, and it can't be apples because that would force both of the other boxes to be right or wrong, neither of which is allowed. say it contains bananas, i know the bananas box has to have apples, so the carrots box is labelled correctly

[@jonrd21]

Its 2 boxes no matter what, see: Apples -> bananas Bananas -> carrots Carrots -> apples Dates -> dates I open boxes apples then carrots. I know it has to be dates, because it isnt apples bananas or carrots. If I open boxes bananas then apples, I still know it is dates for the same reason.

Answer to bonus question: u need 2 1) open the apple box. If its correct, u found it. 2) If its not correct, u also know that the vegetable in the box is incorrect, so if u find banana, u know its not banana or apple 3) ur second box is either carrots or dates in this case 4) if ur second box is correct, u found the answer, if not then the other box is correct. So if u find apples in carrots, the answer is dates in this case.

You can open any second box because exactly three boxes are incorrectly labelled, e.g. in your example, if apple box had bananas, then banana box can not contain apples

[@maxilerlantreas3306]

@@willbobsled That's true, but for example if you open a carrot box and find banana. You immediately knows that banana box is filled with wrong stuff, and it will increase your chances of opening the right box on the second try by avoiding the banana box. Sure, this part didn't matter because the question didn't care about the process. But in my opinion this method is better because it's much more efficient.

The bonus riddle can be answered with just 2 boxes. For the first box, you have a 75% chance to open an incorrect box. Once you see the actual item inside, open the box with that item's label. At that point, you know that the boxes you opened AND the box labeled for the second box's actual contents were misplaced, while the remaining box was pristine. If you opened the accurate box, you already know which 3 boxes are mislabeled, but you can open one of the mislabeled boxes to figure out the triangular direction of the label shift.

[@jedisalsohere]

You actually don't have to check the box with the item's label. If you looked in the box labelled 'Apples' first, and it contained bananas, you then know that the box labelled 'Bananas' is labelled incorrectly. Then, you can check the box labelled 'Carrots'. If it's correct, great. If not, you then know that the boxes labelled 'Apples,' 'Carrots' and 'Bananas' are labelled incorrectly and the box labelled 'Dates' is correct.

About the bonus riddle, I think the maximum time of checking is 2. Here is how I go about this: First select a random box to check, say I check the Apple box, and found banana inside. Then according to the content of the box I can deduce that the Banana box is definitely not containing Banana, which left us with Carrots and Dates box. Finally just check one of the remaining boxes, if you found it, nice! If you didn't, the last box is the correct box. So I figure the maximum is 2, would be nice if someone share their thoughts

[@kaileypeppard3334]

yeah, i believ that is correct

[@thecrookedman3851]

Where did the riddle stipulate that only one box can contain bananas? You fell for the fallacy again.

[@KaiJason]

@@thecrookedman3851 Pretty sure the riddle states that 'each of these boxes contain a different type of fruits' so there would not be two boxes of the same fruit. But your reasoning still stay true, that some other fruits outside of the four labeled (eg. waterlemon) could be inside the wrong boxes

[@ZombieKillerThe]

Or you can pick any 2 boxes at random since 3/4 of them are label incorrectly. Which makes a loop of 3. If you find Apples in the Banana box. You know Banana box must contain either Dates or Carrots and also either Dates or Carrots Box must contain Bananas. By selecting the Apple box and find Dates you will know Dates box has Bananas and the Carrot box contain Carrots. Or you can pick the Dates box and find bananas or the Carrot box with Carrots. Any 2 boxes will give you enough information about what all 4 boxes contain

Also to identify all 4 fruits, you only need to open two boxes. The idea is, the three of them must be permutated in a circle. So you check one and its fitting its label, you go check any other one and know how the permutation goes. If the first one is not fitting you open any other box except for the one labeled as the fruit you found in the first box. Then you can see if it fits its label or if its also part of the permutation (together with the first box and the box which is labeled as the fruit inside the first box).

This has to be my favorite riddle shown so far, simply for how easy it is to be tripped up on it. Its like an unwritten rule that everyone just instinctively follows with the tops

[@mysticalarchives7821]

For the bonus riddle, you would need to check just two boxes to determine which three are mislabeled. The first box you open will either be incorrect or correct. If it's correct, then you know the other three are mislabeled, then you just need to open one more box to see what the correct label should be. To demonstrate the correction, let's say the remaining boxes are box 2,3,&4. Box 1 was correctly labeled as apples and box 2 is labeled as bananas. You open box 2 and find that it contains oranges, which is the label for box 3. To fix the mislabel, you don't even have to look in the other boxes, you just need to move box 3's label of oranges to box 2, put box 4's label of Dates on box 3, and put box 2's banana label on box 4. Why? because if box 3 contained bananas, then box 4 would have to be correct, which we know is false. Thus, if box 2 has no bananas, then neither can box 3. That means the bananas must be in box 4. Two options work for an initially incorrect box as well. If the first box is incorrect, then all you have to do is look in the box labeled for box 1's items and then you know that whatever box is labeled for box 2's items is the third mislabeled box, and again, you know that that box will contain the items for box 1's label. In short, checking just two boxes will allow you to identify the three incorrect boxes and allow you to correct the mistake.

[@user-ht1vg5we2p]

For the riddle at the end: first, I replace the words with A, B, C, and D, for ease. I check box labeled A. If it has an A inside, I'm done. If it doesn't, it has another. Let's suppose that it has a B, since all are symmetrical, and if it had another one (C or D) I would just replace them in the solution and have the results in a simiral way. It really doesn't matter which one I check, from now on. If I checked box labeled C or D and found the correct product, I would have found them. If I checked one of them and found an A inside, the other one of those two would be the correct one. Even if I checked box labeled B, I would find a C or a D inside, and the other one of the two would be the correctly labeled one. Two checks are enough, no matter where the correct box is.

[@Jgaldragon]

For the bonus riddle you open any of the four boxes (example the apple box), if the correct product is inside you know the other three are mislabeled. If it holds another product (say carrots) you know the first box and the intended box for the discovered product are mislabeled. Check the second box (intended for carrots) to find the third mislabeled product. *Similar to the missing instrument puzzle. So at most you would only need to check two boxes.

Answer to the bonus riddle is 2 boxes. You check one box, if it is labelled correctly then you have solved the problem, if not then you have gained information about a second box as well. Since you know what the box you opened contains, say it contained carrots but was labelled apples then you know the box labelled carrots can't contain carrots. So you check one of the other two boxes as they are the only two that could be labelled correctly, either you open the correctly labelled box or the third incorrectly labelled box.

For the bonus riddle You only need to check two boxes. If three of the boxes are mislabeled around, then they have to be in a loop (Apples in the Bananas box, Bananas in the Carrots box, Carrots in the Apples box or some variation). Checking one box will either reveal the one correct box or two mislabeled boxes (the box checked and the box with the label for the contents found). Checking two boxes, however, is guaranteed to reveal either the correctly labeled box (a 50/50 chance) or all of the mislabeled boxes, with which information you can infer that the box not in the loop is correctly labeled.

[@riteshbhartiya6155]

For bonus middle, You have to check 2 boxes atmost. Case 1: If you found correct labelled box in one turn , then no need to check any other. Case 2: But if you checked wrong one, you know that the box you checked is not correct.Also, the box labelled the food you found in 1st box is also wrong labelled. Hence you can check any of the remaining two boxes in next turn to know which one is correctly labelled.

For the bonus riddle: You only need t check two boxes at most. First, you check one at random. If it's correctly labeled, then the job is done. If it's not, look at what fruit it has in it, then check the box with that fruit's label. The content of that second box will tell us which of the two remaining boxes is labeled incorrectly. For instance. You check the carrots' box -> It has apples in it -> You check the apples' box -> It has bananas in it -> If the bananas' box contained the dates, then the dates' box would contain the carrots, meaning that all four boxes would be incorrectly labeled, so the carrots must be in the bananas' box, and the dates would be in their own box, being the only fruits labeled correctly.

For the bonus riddle I think the answer is 2, you check one randomly and if that one is mislabeled you go to the one labeled with the fruit you found in box one, from whatever you find in box 2 you can deduce which one is labeled correctly

[@Adam-jo3tr]

The first one I got right so far!! These are so much fun :)

I've spent WAY to much time trying to figure out if I needed to take the first or third box... xD

[@manmanman4825]

You have to open a maximum of two boxes. If the first box you open is wrongly labeled, check the box that is labeled with what you found inside the first box. The box correctly labeled is the on of the remaining boxes that isn't labeled with what you found inside the second box.

[@kylenetherwood8734]

This is one of the ones where it takes me a few minutes to get but it seems so obvious after that. Also the answer is 2. I can explain it to myself into head but I cannot put it into words.

[@minx.toesies2037]

"Did you solve the riddle"? Nop but I like the animation 😂

[@headcanon6408]

For the bonus riddle: you need to open a maximum of two of the boxes. If the first box is labeled correctly, then you already know which one is correct. Otherwise, you open the box that has the label of whatever food the first box actually contained. It's impossible for this one to be labelled correctly, or for it to contain the food from the first box's label, so it will contain food from one of the remaining two boxes' labels. Whichever one it is is obviously labeled incorrectly, so the other one is the box that's correctly labeled.

[@DoggyBoy-vg8si]

I solved the second riddle for those who want to check: Let’s assume you didn’t get a lucky guess off the bat. If you open the Apple box and it has bananas in it. Then you can assume the Banana box is marked incorrectly. When you open the Banana box, and let’s say it has carrots in it. You then know that the carrot box is marked incorrectly, thus leaving the Date box to be the correct one. So in order to get the guaranteed correctly marked box, you will need a maximum of 2 guesses.

[@fos1451]

Doggy Boy 1320 yeah that’s what I also think

This is the second riddle I was able to solve. YAY.

[@arpitjoshi5611]

I always wonder all the riddle loving intellectuals and no one talks about the solution of bonus riddle.. while for this one my answer is 2

[@lorcanowen-gibbons8889]

hm, i only got it down to three. if the first three you check are incorrectly labelled, you know that the last one is not

[@tinkut8960]

@@lorcanowen-gibbons8889 You can do better because if the second box you checked had the label of the item in the first box, then the box labeled with the item in the second box is also wrong. (Assuming you can't repeat any items.) It's impossible for the second box to contain the first's item because then the other two boxes would have to both be wrong or both be right, which isn't allowed.

[@commmander64]

I know right?!?!

[@mikepagebrand]

The answer to the bonus riddle is two since they're are only 2 possible outcomes: 2 wrongly labeled boxes or one labeled wrong and one labeled correctly. If it's the second you already found the correct box but if it's the first scenario all you have to do is find the box that has the label matches the product in one of the mislabeled boxes

[@girlfoxproduction]

you only need to open 2 boxes. Box A, Box B, Box C, box D if you open box A and it has B stuff you open B it would have C or D stuff, whichever is not in it, has the right label on it.

[@ripmo3503]

Sadly, the rebellion fell apart after the military raid that took place 5/13/18. The military brought more armored vehicles than expected, and they were supposed to receive their only bazooka through the packages, but the box was marked incorrectly, and thus they could not take down the vehicles. However they did deal crippling blows to the national army. Woe to the guy who labeled that box wrong... But srsly great riddle 👍🏻

[@azearaazymoto461]

I've been getting more of them recently, apparently, I'm very good at using the process of elimination. I got both this and the bonus riddle. In the bonus riddle we can assume that all of the labels correspond to one of the 4 boxes. This means apples can't be in the banana box while bananas are in the apple box, otherwise the other two must both be correctly labeled to be able to have one correctly labeled box, but only one is labelled correctly. Since nothing stops us from checking only two boxes, that's the answer, 2. It could also be 1 if you find the correctly labelled box on the first try.

[@TriAzF]

I mean it could only take 1 if you get the correctly labelled box first but it’s asking for the minimum so your right it would at minimum take two checks since once you’ve opened two boxes you are guaranteed to know the correctly labelled box even if you haven’t opened it.

[@circle4602]

Answer: No I can't

[@steamer3930]

1:36 *THEN WHY DON'T WE JUST HAVE ALL THE BOXES HAVE RED LIDS!*

[@strange_and_magnificent]

I’m so glad that I don’t have to solve this riddle in real life, because it would just be a complete waste of my previous time, but watching someone ELSE solve this in a beautifully animated video definitely WOULDN’T.

[@vinitasahu7997]

Simple explanation for the ans. of bonus riddle: The best strategy to find the box labeled right is by choosing a box at random. eg. box labeled Banana. In the best case, the box labeled banana will contain a banana. But if not, proceed to open the box of the fruit found inside the box labeled Banana. eg. Carrots. You may or not find carrots in this box. But if you don't, consider the remaining boxes: Box of Dates (Box D) and Box of Apples (Box A). There can be apples in Box D and Dates in Box A. But since we know that exactly 1 Box contains the fruit that matches it's label, Box A must contain apples.
