Can you solve the secret sauce riddle? - Alex Gendler

[@TEDEd]

Riddlers, we have one more thing to add to the rules! Read this while you pause: the last thing the interrogator says to the chef is: "If you just tell me whether or not the number’s second digit is one, we’ll be done here.” You don’t know whether the chef answers that truthfully, but whatever he says, that makes the interrogator think he knows where the recipe is. Thanks everyone, now back to riddling!

[@BlueDragonFireGirl]

Thank you for pinning that comment. I always watch the 'scenario' once and then try to solve the riddle solely with the aid of rules and hence was a bit dissapointed with the assumption one had to make to solve the riddle. Next time I'll watch the scenario more carefully! Thank you for making so interesting riddles and keeping my brain on the go! :D

[@mauritz3912]

But are they done here because he will give up or thinking he has the right number? If the chef answered different on the last question, would the interrogator give up? and that is why they are "done here"

@@wariolandgoldpiramid It's not about 'understanding' the riddle, it's about not needing to assume something in a riddle (the assumption being that the interrogator asks the last question because he has only two options left). As many pointed out, the interrogator could have asked the last question and got 216 whereas the real locker would then be 729.

The answer could also had been 729, just because the interrogators have 4 options doesn't mean it's not the correct way, I mean they could have asked if the second number was 1 anyway and their conclusion would be that the number is 216 right? I solved the riddle in paper and I got to the conclusion of 729, but when they said "the interrogators must have been undecided between 2 numbers" I said wait what wasn't it 4 Then I went back to the paper and saw it also worked with the 512 and 1000. I'm so confused rn

[@babbycakes173]

They made an assumption that somebody would only ask if the second digit is 1 if they were deciding between 2 options. However I think that it was a reasonable question to ask if they were looking at the 4 options so I think 729 is possible answer.

[@doodleproductions7552]

@@babbycakes173I'm a bit confused, didn't they say "We'll be done here" after answering that question. That implies that no matter what the answer, they'll have a locker number in mind. If there were 4 options, then they would not say "We'll be done here" because depending on the answer they may have more questions to ask. However, this wasn't included in the rules but it would have helped people understand

[@doodleproductions7552]

As I said to Lollipops (sorry I wasn't sure if my reply notified you and I wanted to be sure that you understand why it was assumed there were two options) they also said "We'll be done here" after the question, you can read my explanation to the other person to understand a bit better.

[@SickRedApple]

@@doodleproductions7552 Ah you have a point there, though they should have included that in the overview. I used that to work it out and came to the conclusion that there were four possibilities, because they didn't include the 'we'll be done here' part

[@KarishmaChanglani]

The interrogator says that the question about the number 1 is the last question and then they are done here. Meaning that was all the information he thought he needed. So there cant be more that 2 numbers since the question can only eliminate 1 number at most.

[@pragatisingh6020]

Exactly what I thought. Why haven't we considered the chef truthfully saying no to the third question? This riddle seems faulty.

[@susamogus8331]

[@Inkyminkyzizwoz]

@@pragatisingh6020 Because when the interrogator asked the chef whether the second digit was a 1 he said they'd be done, which means that he must've narrowed the options down to two possible numbers, and that could only be the case if the chef said that it was a cube

[@BlueDragonFireGirl]

Wouldn't one of the rules have to be something like 'The interrogator tries to ask as few questions possible'? I didn't came to the conclusion that the last question was asked sorely because he had 2 options (512 and 1000) left. I mean it makes sense but it's possible that if the chef would have answered 'no' to the last question and there were still many options left, and the next question would've been "Is the number's second digit a 2?". For instance: yes x^2? -> yes x^3? -> no -> leaving us with 16,25,49,81,100,121,144,169,196,225,256,289,324,361,400,441,484 2nd digit a 1? If the chef would have answered with yes, then the answer would be 81 and the interrogator would leave. Then we would apply the 'correct' answers: no x^2? -> no x^3? -> no Conclusion: A whole bunch of numbers are left (785 numbers to be exact - all numbers between 500 and 1300 that are no perfect squares or perfect cubes). But if the chef would have answered no to the 'second digit a one' question, there would still be the options '16,25,49,100,121,144,169,196,225,256,289,324,361,400,441,484' and the interrogator continues to asks question (like 'Is the number double-digit? Ist the square root double digit? Is the second digit a 2?' ect.) I hope you understand what I meant (: Thanks for your riddles. I really enjoy them!

[@timokupo]

It's a bit annoying because without the assumption, the riddle is unsolvable.

[@stormsurge1]

Agreed. Without that assumption the answer is one the numbers between 500 and 1300 that have second digit 1 and are not 512. And no way to know for sure which one. Badly formulated problem.

[@sebastiandierks7919]

Exactly my thoughts as well. Only I would have thought "2nd digit" meant the 10er digit, so in my solution the interrogator would have concluded 16 instead of 81, which doesn't change the fact that there are more solutions than the number 64 from the video. Also there is the possibility that the prisoner answered

[@ghostderazgriz]

That is true... but if the interrogator didn't know what the lock box number was then he would have asked more questions. The idea is that whatever the chef said, the interrogator is convinced he knows what the number is. You also have to consider the question's phrasing. He asked "does the second digit have a 1". You don't ask a question that specific unless it identifies your goal. And the only way it can is if there are only 2 numbers left to determine.

[@eyozin]

Your biggest clue was: The riddle is solvable (because they all are... the good ones at least). With that in mind you should have known you were on the wrong track and look for an alternative solution. I know... only going by the information the video gives us you are absolutly correct but you know more than that. That's all I'm trying to say.

I love how the riddles are actually challenging. These riddles challenge your mind to think beyond. That’s exactly what I love about these TedEd riddle. Keep making more please.

[@markmcarthur5090]

Ted-Ed are slightly incorrect. The interrogator doesn't need to narrow the numbers down to two options for an answer to "Is the number's second digit a 1?" to give him a final number. If he has narrowed it down to several numbers which don't have a 1 as the second digit and one number which does, and he is given the answer "Yes", then he would think he knew where the secret sauce was. For example, if he believed the number was a square below 500, the only square between 13 and 500 with a 1 as the second digit is 81. However, the interrogator says "If you just tell me whether or not the number's second digit is a 1, we'll be done here." This statement is a necessary piece of information which does mean Ted-Ed's deduction is correct, but this statement was not included in the summary or ever referred to.

[@alfredjohnson3642]

I think my answer of 729 is also correct, If you assume the answers of the questions are yes, no and yes then by knowing when he is telling the truth you end up with no, yes and yes therefore the only answer is 729

[@ghostderazgriz]

I disagree. If the interrogator had more than 2 numbers to debate and asked that question, the answer to that question will only isolate one value. Which means he still needs to ask more questions if the isolated value is not the answer, it would be a waste of time. If you ever played 20 questions, you know the starting questions are always general ones "is it a mineral, is it an animal". If the first question is "is it a nocturnal predator with 3 toes and hunts at 8:33pm every other tuesday" and the answer is no, then you only eliminated one possible thing. Specific questions like "is the second digit a one" are only used when the narrowed margin of possible answers is few enough that asking the question eliminates all other possibilities which could only occur if there are only 2 options left.

[@markmcarthur5090]

@@ghostderazgriz You're right that if there are more than two values and the interrogator asks that question, he might be wasting his time and only manage to rule out one of many options. However, it is not impossible for him to have several remaining options, ask that question, and have it narrowed down to 1. It would be an unusual strategy for him to take, but we can't assume he acts in a certain way if we want to be certain about the answer.

[@markmcarthur5090]

@Chester Lloyd Doliente You're right, there are several possible answers that the interrogator could end up believing if we don't assume he has it narrowed down to two options. I gave one example. Because the interrogator states that the answer he gets will give him a final number, Ted-Ed's answer is the only correct answer. But without that statement, there are several conclusions he could reach and many, many possible locations of the secret sauce.

Oh that makes sense. I also forgot about that bit of dialogue about the burglar knowing that question would be the final one. The way I figured it, between 13 and 1300 there are two perfect cubes that have a 1 in their second digit, 216 and 512, and since 216 is below 500, and 512 is above 500, and the burglar thinks he knows weather the number is below or above 500, he would be able deduce it from there.

@@americantoastman7296 It's not though. The assumption that before the last question there were only 2 options remaining is not based on anything.

[@Enaronia]

@@SickRedApple Right, what we actually know is that after the fourth question there was only one possibility. We don't know that after the third there are only two. That wasn't based on anything.

[@Cuuniyevo]

@@Enaronia After the first question, we know the interrogators had hundreds of options. After the second, they either still had hundreds (if no to squares) or only 14 (if yes to squares). After the third, the reason we know they had it narrowed to exactly 2 is because they said they only needed one more question and they'd be done. That is what clues us in to the chef answering "yes" to it being over 500, "no" to it being a square and yes to it being a cube, leaving 512 and 1000 as the only non-square cubes left. If it were "no" to being over 500, there are 17 squares and 4 cubes with only 1 overlap. The question about the 1 would either be entirely superfluous or possibly not the last one needed. Unfortunately, the bit about it being the last question they needed wasn't stated in the rules for the riddle on the part where we pause and think about it, so it's easy to forget. Without remembering that part of the story, it's still solvable, but seems more like a lucky break.

These are the worst interrogators to not just ask what the number is

[@samarendra109]

Everyone who are thinking that there are multiple solutions just listen to the video again carefully. While asking the last qu the interrogator says " *Now if you will just tell me wheather the second digit is one or not we will be done here* ". This means what ever the answer might be he would have narrowed it down to one number. Hence the conclusion that before that qu he must have narrowed it down to 2 numbers.

[@miguellugo1200]

You're right. I missed that and thought there could be more than 2 final numbers. Nice catch!

1156 is the only square number above 500 and 81 the only one below 500 whereas the 2nd digit is 1! So if the spies ask whether the second digit is 1 and he answers with yes they should know either.

[@pianofortekang]

@@vaujam8539 moreover, why should we assume by the time the interrogator asks the last question they have already narrowed it down to two numbers. Let's follow the logic Ted goes through. They identify that the chef must have said the number is NOT square, which I agree with. But Ted "deduces" that the chef said the number is higher than 500, as this is the only way it leaves us with two options, 1000, and 512. But why? It is possible the chef said the second digit is 1, then it is totally possible that the chef said the number is smaller than 500 as then the only number which fits all the conditions is 81, thus the interrogators think they know the number.

[@delightfulkissboy8926]

They're assuming it's true in order to test which line of answers leads to 2 possible answers for "Is the second digit 1?". They could have started by assuming it's not a perfect cube, but that only leads to lines of questioning where there is only 0 or 1 possible answers to "Is the second digit 1?"

i feel very proud of myself for finally solving one of these myself

[@Anonacho5459]

You have to add in the card thingie (1:56) that the interrogators specifically said that they'd be done after asking that last question. I skipped to 1:56 and got the answer quickly as 729, because I assumed it went like this: Chef says yes to the number being less than 500, chef says no to the number being a perfect square, chef says yes to the number being a perfect cube.... in which case leaves the options 8, 27, 125, 216, 343. As weird as it sounded, I assumed the interrogator was just asking a random question at the end to confirm which of the numbers it was, which I didn't care about since I'm trying to find the real code. I concluded that in reality, the number is more than 500, and is a perfect square and a perfect cube. In which case the only options were 729 and 1000, since 729 was the only option that was a perfect square and a perfect cube I concluded it was that.

[@josguil]

This comments needs to be higher, it's vital info that is not in the card

[@dragorn3212]

I got 729 as well. The issue is the 4th question doesn't actually need to be narrowed to 2 numbers, it could have been narrowed to 27, 125, 216, 343 and if the 4th answer is yes then the interrogators have determined that 216 is the number. So therefore we can't determine that the number is suppose to be below 500 based on this. And the solution if the number is above 500 is 729

That's the same thing I thought! I kept going back and forth the video to see if I got anything wrong but they clearly say that he lies but we don't know the answer, so it could be both yes and no. Fuuuuuu!

[@Inkyminkyzizwoz]

*then - it's bad enough seeing people CONSTANTLY getting it wrong the other way round! And you deduced the chef's answers from the fact that the interrogator must've narrowed the options down to two numbers with one having a 1 as the second digit, which is why he said they'd be done there after that question

[@emilypiens2355]

There's actually a possibility that if the answer on the last question was yes (wich we don't know but could be) that the interrogator goes to 216 if the answers where yes (less that 500) no (not a square) and yes (a cube) with a yes on the 2nd digit Being a 1 this would make the correct answer 729 (it would be greater that 500 and both a square and a cube wich is the case) this would be avoided if you add that he tells the truth on the last question (since this only can happen if he says "yes" to that question and the second Digit of 729 is not 1 so this scenario becomes impossible) I got stuck for ages trying to find An answer to that i also don't really like the aspect of having to use "I have to be able to solve it so therefore this scenario is impossible" just imagine the answerseries "yes yes no yes" the interrogator would think it is 81 and you wouldn't be able to solve it becouse you have to many options A Parallel thing happens with "no yes no yes" the interrogator thinks it's 1156 and you can't solve it But maybe that's just my opinion

[@gandinsk]

[@saadhesham4965]

I got the 216 and 729 one too, it just seems this riddle has too many things for the maker to be able to be absolutely sure there are no other true answers

[@1323545624]

You are mistaken because the interrogator himself is sure, he will be done after the last question even though he does not know the answer yet. Therefore there can only be two options left at that point, which rules out all of your scenarios.

[@wariolandgoldpiramid]

Well, let's imagine the answers were "Yes", Yes", "No", "Yes". Is it less then 500? Yes. So it's 13~499. Is it a square? Yes. So it's one of the squares between 13 and 499. The possible solutions are: 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484. Is it a cube? No. Therefor, we remove 64. However, that still leaves the interogators with 18 possible answers. However, the interogrator is suppose to be garanteed to be able to get the solution, regardless of what Answer 4 is. Therefor, this solution is imposible. Now, let's look at scenario "No", "Yes", "No", "Yes". Is it less than 500? No? Therefor, it's 500~1300. Is it a square? Yes. Therefor, it's one of the following: 529, 576, 625, 676, 729, 784, 841, 900, 961, 1024, 1089, 1156, 1225, 1296. Is it a cube? No. So, we remove 729. But that still leads us with a lot of numbers. And again. You must have not understood the last clue. The interogrator says: "If you just answer if the second digit is a 1, we'll be done". What this means is, "if you tell me weather the second digit is a 1, then I'll be garanteed to know the answer, regardless of what you tell me". Which is NOT true in this scenario. You see, we aren't actually suppose to analyze what the interogrator will know after question 4. We need to analyze what he knows before question 4 is asked. And make sure that what the interogrator says is true, that he needs an answer to question 4, and that no matter what the answer to question 4, he will be garanteed the answer. Okay. I admit it. After I typed all of this out, I understand what the problem with this riddle is. The math is absolutly correct. It's just that not everyone were able to understand that: 1) The interogator will not ask extra questions if he doesn't need them, hense he needs question 4. 2) The interogator will be garanteed to know the number, regardless of what the Chef answers. I was perfectly able to understand these two things myself. But I can see that it wasn't explained as best as it could have been.

[@layladuew5911]

damn so i’m one of the best spies but i can’t even read lips for yes or no?

[@SpicyRocketSauce]

Great video, but you didn't include the most important clue in the pause screen: before asking "is the second digit a 1?", the interrogator says "one more question and we'll be done", which is how you know he's narrowed it down to two numbers.

[@siyaadpaikar3498]

It has to be a perfect cube in order to narrow down the options since by the end of the interrogation, the interrogator knew the answer or else he would hv asked more questions. Options:27,64,125,216,343,512,729,1000 However, there's another possible situation: If the chef had said that the number is smaller than 500, not a perfect square, and has 1 as the 2nd digit...the interrogator would have narrowed it down to 216. We don't know whether the 2nd digit has 1 but we do know that it is a square number and greater than 500 since the chef lied. Then, the only number greater than 500 having a perfect square is 729. This is just an alternate answer which was not considered in the video.

[@starmic1852]

I've seen people get 729 but only by ignoring the implication that the interrogator narrowed it down to ONLY two options with the "We'll be done here. (Though some argue that this implication wasn't 100% clear). The interrogator narrowing it down 216 would be from 5 options which wouldn't make sense giving the wording of the problem.

[@markimbing8018]

That would be too much to work with. That would leave them with 1280 options to check. In this case, it would be easier to assume the answer to the perfect cube question is yes. If that didn’t work, then we can check the 1280 options left between 13 and 1300.
