Is there an issue? It's perfectly logical to receive all information possible if it's being presented to you with no consequences. If there's no risk for receiving the additional clues, why wouldn't you take them?

Alternate logic you can use: *The third clue must be important. *Therefore, there must be a wrong answer where the last two digits are identical. *The only set of factors that meets that criteria is 1, 6, 6. *If 1, 6, 6 is the wrong answer, there must be another set of factors with the same sum. That's how I solved it.
There are a lot of riddles based on that. Stuff like figure out the age of three persons and the final hint is something like "my oldest daughter is playing the piano". Sounds completely unrelated but the "older" part is giving the important information.
@@bensoncheung2801 I don’t think they took into account the second clue given, which is that the is that the sum of their ages equals the house number (and that the student said that wasn’t enough information to figure it out). 1+4+9 is 14, while 2+2+9 is 13.

This actually the Three Daughters problem. A classic. A student asks his teacher: How old are your three daughters? The teacher says the product of their ages is 36. The student says this is not enough information. The teacher says if you add them up you get my house number. The student says this is still not enough information. So the teacher says the eldest one plays the piano.
Her saying “the eldest one” tells you that it must be the choice of 2,2,9 because if it were 1,6,6 there wouldn’t be an eldest one since the oldest are both 6
I've been watching these riddles over and over and this is the first one I got. Gotta start somewhere. Oh, also TED, if you're looking for a guest speaker, I'm a certified genius now, I'd be happy to discuss my innovative mind.
That part where it says she could have entered the code after the second clue threw me off, because I thought that she already had the answer, but was asking for a third clue for the benefit of the listeners, not that she didn't yet have the answer.
If you know the answer after two hints it benefits the listeners more to not ask for a third clue (It eliminates [2,2,9] and [1,6,6] instead of just [1,6,6]). Plus the listeners also get a huge benefit when you ask for a 3rd question when they know you wouldn't if you already had the solution.
That really depends, Bradley... If she knew the answer after the second clue, and she left right then and there, her companions would have 6 possible answers with no way to determine the right one. Since she doesn't know what the third clue is, that clue might've been exactly what they needed to narrow it down to 1 answer.
+Bradley Good point, however she does not know what the clue is before asking for it. That means can't know how many possibilities a third clue could eliminate. It would be in her best interest to ask for a third clue to eliminate as many as possible.
She knew what number hallway she went through. After adding up the digits, she saw that two of them were the same, 13, while the rest were different. Since she already knew her hallway number, she could have left, if all of the sums were different. However, knowing she went through hallway 13, she didn't know which combination if 13, therefore she had to ask for a third clue. She wouldn't have needed that third clue if all of the sums were different, because she went through one hallway, and she knew which hallway it was.
yea I guessed the right answer, but I was so unsure of it when they pulled up the list of all the possible answers most of which I didnt think about lol
in step 1, they shoulda eliminated the codes with double digit 3rd number since the passcode only allowed for 3 digits total. So like it couldn't be 1*3*12 because that's 4 digits. Not that it mattered but still
+DrGerbils It doesn't have to, because it fits 1 digit per box. If it did fit 2 digits per box...how do I move on to the next digit box? Where on the keypad is the space/tab bar? If it were capable of 2 digits per box then it would be 6 digits meaning most importantly and finally where is 0? Because if it's 2 digits then there has to be a 0 in front of any number less than 10, and numbers with 0 like 10, 20,etc (Ex....A date written numerically is commonly written mm/dd/yyyy 8 digits. If today is March 3 2016 I'd have to put 03/03/2016). If it wasn't there then the number placed like for example the code 557 would then need to be typed 55, 55, 77 in order to move to the next digit place but the computer will see it as seventy-seven not seven. So no its 1 digit place per box because of the absence of 0 or some form of moving to the next box while filling in the space....sorry :p.
BATMAN BRUCE WAYNE u know that's just 0.1 seconds right. I think what u were looking for is 0.0000001 seconds and ***** it's nanosecond idk if attosecond is even a real word. The real Batman told me to tell u guys that
Teenage Hustler attoseconds are real lmow just do a simple google search "An attosecond is 1×10−18 of a second (one quintillionth of a second). For context, an attosecond is to a second what a second is to about 31.71 billion years. The word "attosecond" is formed by the prefix atto and the unit second. Atto- was made from the Danish word for eighteen (atten)." wikipedia is my source lol
Looking at the keypad I (wrongly) assumed that all three numbers are single digit. So it can be 6 6 1 or 3 3 4 or 2 2 9. Since she new the answer by second clue, but went for the third clue to help other guys, it must be 3 3 4.
Spencer Geller she asked the third clue because 3 means she started from the first clue and ended in the third, i.e, 1 to 3 (1-3) which can be considered 13.
I did the same thing! I'm going to do this with my students today (middle school) and suggest they list ALL possibilities and not worry about the keypad being 1-9 ;-)
I started from the back. Zara could not find the combination of 3 numbers without 3rd hint. Which means the hallway number can be deduced by using same number for 2nd and 3rd number. Since 1st hint states that product of all 3 numbers is 36, it is easy to guess that number is 1x6x6 (none other numbers work) which means, due to 2nd hint, the hallway number is 13. Now you can get correct numbers. The answer is 2x2x9. :)
I thought Zara asked for the third clue regardless if she had found the combination using the first 2 clues, just because she wanted to make sure the other 2 would be able to figure it out correctly.
"You're sure Zara remembers the hallway she entered, but she can't tell you what it is" so what you're saying is I don't have enough information to solve it yet "If she could escape with just two clues, she would" I have to be honest Zara does not sound like she understands the concepts of teamwork and loyalty as well as she understands logic
its 1 1 36. 1 x 1 = 1 1 x 36 = 36. 1 +1 = 2 2 +36 = 38. without the clues she couldnt find out the passcode because one is unique and it has to be acending. . . i dont actually know but im paused trying to figure it out. WISH ME LUCK !!!
And this is why super villains always lose. They let their nemeses play logic games like this instead of just killing them right then and there and being done with it.
Yes. I would happily be the undead dictator wizard magician who ate the fire crystal and is somehow a cheating royal who can’t figure out what this troll wants. And learning about gold and silver coins inside a temple that will be found with Robo ant guards that have an ancient virus that are trying cross a river, after I eat some secret sauce while killing vampires that are pilgrims that are death racing with a huge indestructible blobs. With rebel supplies and mondrian squares over a bridge jousting with dragons and alien probes finding sea monsters guarding treasure and getting into jail, then fighting giant cats and werewolves. And collecting stolen rubies and counterfeit coins while going on a rescue mission across dimensions and time. On a airplane with pirates eating eggs and talking with Einstein and three gods. On lockers with planets and on those planets have prisoner boxes with endangered fish inside. AND ALL OF THAT...with a frog that can save you from that poisonous mushroom
2, 2, 9, please tell me I'm right. I focused on the clue that she needed all 3 clues, the last being that the last number is unique, which insinuates that her previous answer broke this rule therefore I got the equation: x*y^2 = 36. After thinking a while, I realized 36 had the root of 6, so simply 1*6^2 = 36. If I thought this was her answer after rule 2, it must satisfy rule 2,therefore I can get the hall number n, since x+2y = n, 1+2(6) = n, n = 13. After this I went on a tangent trying to solve mathematically, but realized there was a strictly finite range of possibilities given whole numbers, so I just used trial and error. Since the last number was the most, I need to find a number, which was more than 6 since that's roughly half of 13, and less than 13 obviously, which satisfied the two equations: a*b*c=36 a+b+c=13 Since I was basically already using the second equation, I just needed to check against the first. So, 7? nope, 8? umm... nope. 9? 13-9=4, 36/9=4... OoO, And that's basically how I came to a conclusion. Time to press play and cross my fingers.
Work out all possible solutions for 36, lol, my brain's nowhere so capable. But yessssss! I got it, my first Ted riddle solved, yay. Though you guys make it seem obvious :'(
This riddle is bad, it works backwards. and your equation is bad, you ignore 1 can be one of the number. If the sum of the comb is not 13, she won't be able to pass the hall way number. according to the reason, My conclusion is that Zara is a selfish little kid.
Eh, if it turned out the sum wasn't thirteen, then the other two could go to doors 10, 11, 14, 16, 21, and 38, and punch in the codes "3, 3, 4", "2, 3, 6", "1, 4, 9", "1, 3, 12", "1, 2, 18", and "1, 1, 36", respectively, until they ran into a door whose electric gate came down, even if the doors lock you out after one attempt each.
Yaoxing Li You mean 36*1^2=36? Meaning the hall number could be 36+2(1)=38. This one couldn't be it since 1 < 36, and they have to go lowest to highest in the equation.
What if Zara deliberately asked for the 3rd clue because she knew (with her “perfect logical reasoning”) that there was no way the others would know the hallway she entered, and so attempted to gain more information through the audio transmitter?
I'm a Japanese. Recently, I have watched ted-ed and started solving riddle. But, I usually can't🥺🥺 However, I enjoy solving!!! I'm so excited about your movie!! I am very sorry for my poor English.
sums: 2,2,9 = 13 2,3,6 = 11 3,3,4 = 10 1,3,12 = 16 (may be invalid because keypad?) 1,2,18 = 21 (see above) 1,1,36 = 38 (see above) 1,6,6 = 13 So 1,6,6 and 2,2,9 have the same sum meaning that clue number 3 would have been necessary for her to figure it out. So the answer is 2,2,9 on hall 13. Now to unpause and see what they did.
Inkyminkyzizwoz - If we assume that the keypad only accepts single digits as an entry, then the double digit numbers wouldn't count. However, the answer wasn't dependent on knowing that.
Alright, so I’m not a native English speaker and these riddles were the main reason I learned what „even number” means in English. Thank you for that, TEDEd.
Zara should have inserted the wrong number, so she’d been thrown back in with the other two, then she could have said the right answer, and they could’ve escaped at night?!
Why would she risk being thrown back into another dungeon, without any knowledge if they could sneak out at night, when she could save herself AND tell the others by leaving and telling them the password through the transmitter? You are not a perfect logician ;)
Jandalph Well, she's a perfect logician so she should leave whenever she knows the answer and not worry about her friends. So she would leave them to die. Luckily they could escape with her.
1) Went through all possible sets of whole numbers that can multiply to 36 in increasing or equal to order, including ones where the largest number is NOT unique. 2) Found their sums. For the last clue to be needed, that means that there were two or more solutions using the first two clues. The only sets of numbers that this works for is 1, 6, 6 and 2, 2, 9, which both multiply to 36 and add up to 13. 3) The final clue makes it so that 1, 6, 6 does not work. By default it must be 2, 2, 9. Let's see if I'm right!
I did not watch the solution yet, but I am going to say mine first. I think the answer is 229. First of all, the first clue is that they all multiply to 36. I narrowed it down to these codes: 1, 4, 9 1, 6, 6 2, 2, 9 2, 3, 6 3, 3, 4 The second clue was that they all add up to the hallway number you entered. Those sums, in order, are 14, 13, 13, 11, and 10. The last clue is that the last digit is used only once. The only code I can eliminate is 1, 6, 6, which adds up to 13. If eliminating that code gives her enough information to escape, she must know that the digits add up to 13. The only other code that adds up to 13 is 2,2,9. That is my final answer.
Okay, I am clearly deaf. I thought that there can only be single digit numbers, but the numbers actually can have two digits. But I do not think that would affect my answer at all since none of the codes with two digit numbers in them add up to 13. 229 would still be the only other one.
Yeah, darn it. What he said in the solution made me think that you can put a two digit number in each slot. So, he made the solution a little more complicated than it is supposed to be.
Alternatively, solve clue 2 last. The prime factors of 36 are 2, 2, 3, 3. Clue 3 helped Zara so one of the possible solutions before hearing it must have included one where the biggest number appears twice. The only number we can make appear twice and still be the biggest is 6, in the code 1-6-6. (If 3 appears twice, the other number has to be 4 which is greater than 3.) 1+6+6 = 13, and the only other possible code that adds to 13 is 2,2,9 so this must be the answer.
You're allowed to remove them as possible outcomes. I eliminated them as possible outcomes because a numpad lock cannot have double digits. I solved it quicker then because I didn't need to write out or add up extra series of numbers.
Zara could have asked for the third clue in order to provide some extra information to her friends, as she saw that they would not be able to escape using just the two clues they heard, unlike her
I like the riddle, but it has one serious flaw: Zara knows that the other two are going to be escaping based on the information she manages to feed them, and that the first two clues aren't enough to narrow it down for them. So even if SHE could have solved it with just the two clues, she still would have asked for a third one to help her friends, meaning you can't infer the hallway number and the whole thing falls apart.
I got it! Yey! I factorized 36, found the 8 combination then noticed the 2 sums of 13. But I thought it differently. If a 3rd clue is needed, then it must be information, not data. Therefore if the correct answer was, let say, 14, the 3rd clue wouldn't be a clue at all. So, yeah, maybe it's not 100% the correct method, but it worked... Still, the explanation is a little confusing since Sarah knew the answer at clue #2 (and the guys would have known that she could already escape). The FACT that she asked for new information (the 3rd clue) is information itself, even though she didn't need to ask for it.
javierr8 except she didn't know after the second clue. Though she of course knew her hallway number, there were two answers where the product of all three numbers was the same as her hallway number (13). So she needed that last clue to figure out which of the two was correct.
"The FACT that she asked for new information (the 3rd clue) is information itself" : Correct. Even if there would have been 2 others numbers that would have summed up to a same number, the fact that she knows after the 3rd clue (knowing the sum) means that the solution that ends up with the square root of 36 WAS considered and now isn't. This tells us in what hallway number she is ;)
I had a similar notion but had missed the information that "if she could enter the passcode now (after clue #2) she would"...and was thinking she was asking for the third clue for the other two and not for herself.
I'll add some hints below. Use them one at a time if you can't solve this riddle: Hint 1: Try writing out all of the possible combinations of three numbers that multiply to 36 (i.e. 3 + 3 + 4 = 10). Hint 2: There are eight possible combinations you should have written down. Hint 3: If Zara had been standing at door 10, she wouldn't have needed the third clue because the code to door 10 would be 334. Which door must she have been standing at in order to need the third clue?
Thank you. I watched the video all the way through and couldn't understand what determined the hallway, but your hints made me understand the premise of their third clue.
This riddle I found it out by myself. The key is zara's change upon the third clue. Without it she can't determine the numbers and with it she can. Since the third clue is "large number is unique" there must be at least one potential situation "largest number in dual or more" suits all former preconditions thus blocked her solving with only 2 clues. The only combination with largest number in dual is 1*6*6 and that leads to a sum of 13. All other potential solutions must follow this or got crossed out upon the second clue. And that remaining combination is 2*2*9.

If you know the answer after two hints it benefits the listeners more to not ask for a third clue (It eliminates [2,2,9] and [1,6,6] instead of just [1,6,6]). Plus the listeners also get a huge benefit when you ask for a 3rd question when they know you wouldn't if you already had the solution.
That really depends, Bradley... If she knew the answer after the second clue, and she left right then and there, her companions would have 6 possible answers with no way to determine the right one. Since she doesn't know what the third clue is, that clue might've been exactly what they needed to narrow it down to 1 answer.
+Bradley Good point, however she does not know what the clue is before asking for it. That means can't know how many possibilities a third clue could eliminate. It would be in her best interest to ask for a third clue to eliminate as many as possible.
She knew what number hallway she went through. After adding up the digits, she saw that two of them were the same, 13, while the rest were different. Since she already knew her hallway number, she could have left, if all of the sums were different. However, knowing she went through hallway 13, she didn't know which combination if 13, therefore she had to ask for a third clue. She wouldn't have needed that third clue if all of the sums were different, because she went through one hallway, and she knew which hallway it was.
i didn't know 18 was a digit on a FUCKING SINGLE DIGIT NUMBER PAD
In the end it didn't matter. However, I did automatically eliminate all options that had a double digit number within.
It's a number on a single digit number pad

+_Orange Qulava805_ Same :P
yea I guessed the right answer, but I was so unsure of it when they pulled up the list of all the possible answers most of which I didnt think about lol
yea, feels good man ahah
Same haha
in step 1, they shoulda eliminated the codes with double digit 3rd number since the passcode only allowed for 3 digits total. So like it couldn't be 1*3*12 because that's 4 digits. Not that it mattered but still
I thought I was the only one....I'm like its a 3 digit code with a 9 number keypad no way I'm fitting 12, 18, or 36 in that XD.
I thought so as well.
I thought the same thing but the answer still doesn't change.
The puzzle never says anything about the code being limited to 3 digits.
+DrGerbils It doesn't have to, because it fits 1 digit per box. If it did fit 2 digits per box...how do I move on to the next digit box? Where on the keypad is the space/tab bar? If it were capable of 2 digits per box then it would be 6 digits meaning most importantly and finally where is 0? Because if it's 2 digits then there has to be a 0 in front of any number less than 10, and numbers with 0 like 10, 20,etc (Ex....A date written numerically is commonly written mm/dd/yyyy 8 digits. If today is March 3 2016 I'd have to put 03/03/2016). If it wasn't there then the number placed like for example the code 557 would then need to be typed 55, 55, 77 in order to move to the next digit place but the computer will see it as seventy-seven not seven. So no its 1 digit place per box because of the absence of 0 or some form of moving to the next box while filling in the space....sorry :p.

I assumed the digits could only be 0-9 (like a typical number pad). Luckily the solution still fell within that so I still got it right. 😅

alright, and we're gonna totally ignore the fact that Zara almost ditched us and left us for dead.
look how easy we escaped at night. she had no excuse
2:18 is the funniest screenshot in ted ed riddle history
I got it by a different way. I thought the girl deliberately asked for the 3rd clue (1-3) so that they can guess the hallway number.
I thought the same thing based off his wording, but for me, that left it unsolvable. I don't know how you could solve it an alternative way.
Looking at the keypad I (wrongly) assumed that all three numbers are single digit. So it can be 6 6 1 or 3 3 4 or 2 2 9. Since she new the answer by second clue, but went for the third clue to help other guys, it must be 3 3 4.
Spencer Geller she asked the third clue because 3 means she started from the first clue and ended in the third, i.e, 1 to 3 (1-3) which can be considered 13.

@@sreeharis7466 But that wouldn't help the other guys, as the third clue only eliminates (1,6,6) from the group! (2,2,9) would still be valid, too.

MORAY EEL that would take too long
Irish Virador you could just put it under the light of those electric Gates and examine any reflection
There will be people who got them wrong
And the fingerprints don’t give the order either
Hey Plays but will be able to use the second clue to determine what order it was in because we'll already know what buttons she pressed
I had eliminated all numbers greater than 9 as only one digit can be keyed in. That, of course, took me off track.
Sumit Pal this is what threw me too, it looked as only if single digits was allowed.
They said numbers, not digits
I did the same thing! I'm going to do this with my students today (middle school) and suggest they list ALL possibilities and not worry about the keypad being 1-9 ;-)
Same. Especially with the keypad animation at 0:31.
Yes that part was unclear
I started from the back. Zara could not find the combination of 3 numbers without 3rd hint. Which means the hallway number can be deduced by using same number for 2nd and 3rd number. Since 1st hint states that product of all 3 numbers is 36, it is easy to guess that number is 1x6x6 (none other numbers work) which means, due to 2nd hint, the hallway number is 13. Now you can get correct numbers. The answer is 2x2x9. :)

2, 2, 9, please tell me I'm right. I focused on the clue that she needed all 3 clues, the last being that the last number is unique, which insinuates that her previous answer broke this rule therefore I got the equation: x*y^2 = 36. After thinking a while, I realized 36 had the root of 6, so simply 1*6^2 = 36. If I thought this was her answer after rule 2, it must satisfy rule 2,therefore I can get the hall number n, since x+2y = n, 1+2(6) = n, n = 13. After this I went on a tangent trying to solve mathematically, but realized there was a strictly finite range of possibilities given whole numbers, so I just used trial and error. Since the last number was the most, I need to find a number, which was more than 6 since that's roughly half of 13, and less than 13 obviously, which satisfied the two equations:
a*b*c=36
a+b+c=13
Since I was basically already using the second equation, I just needed to check against the first. So, 7? nope, 8? umm... nope. 9? 13-9=4, 36/9=4... OoO, And that's basically how I came to a conclusion. Time to press play and cross my fingers.
Work out all possible solutions for 36, lol, my brain's nowhere so capable. But yessssss! I got it, my first Ted riddle solved, yay. Though you guys make it seem obvious :'(
This riddle is bad, it works backwards. and your equation is bad, you ignore 1 can be one of the number. If the sum of the comb is not 13, she won't be able to pass the hall way number. according to the reason, My conclusion is that Zara is a selfish little kid.
Eh, if it turned out the sum wasn't thirteen, then the other two could go to doors 10, 11, 14, 16, 21, and 38, and punch in the codes "3, 3, 4", "2, 3, 6", "1, 4, 9", "1, 3, 12", "1, 2, 18", and "1, 1, 36", respectively, until they ran into a door whose electric gate came down, even if the doors lock you out after one attempt each.
ArticulateDuck what if they killed you or got you killed after one attempt or worse, cause you to get expelled from school.
Yaoxing Li You mean 36*1^2=36? Meaning the hall number could be 36+2(1)=38. This one couldn't be it since 1 < 36, and they have to go lowest to highest in the equation.

However, I enjoy solving!!! I'm so excited about your movie!!
I am very sorry for my poor English.
The Combination is also the first second of the video where he starts explaining the solution. (2:29)
sums:
2,2,9 = 13
2,3,6 = 11
3,3,4 = 10
1,3,12 = 16 (may be invalid because keypad?)
1,2,18 = 21 (see above)
1,1,36 = 38 (see above)
1,6,6 = 13
So 1,6,6 and 2,2,9 have the same sum meaning that clue number 3 would have been necessary for her to figure it out. So the answer is 2,2,9 on hall 13.
Now to unpause and see what they did.
Huh, I missed the 1,4,9 combination, but hey! I still got it right! Yay!
Because keypad what?
Inkyminkyzizwoz - If we assume that the keypad only accepts single digits as an entry, then the double digit numbers wouldn't count. However, the answer wasn't dependent on knowing that.
I was wondering the same thing too. The password must be entered with single digits only not 2.
1,6,6 is incorrect becuz last number had to be unique but hey, you're a smart lad!
Wait, why didn't she purposely say a wrong answer, so she could return and tell them the answer
Tell them the code*
If she said the wrong code or anything for that matter, they would be thrown into the pit. Listen to the story -.-
no, she would only be thrown back into the dungeon. they wouldnt be thrown into the pit til next morning.
But she can fly she wouldn't fall down if she don't want to.
+Exertuz she doesnt get a second chance, obviously...
Alright, so I’m not a native English speaker and these riddles were the main reason I learned what „even number” means in English. Thank you for that, TEDEd.
Zara should have inserted the wrong number, so she’d been thrown back in with the other two, then she could have said the right answer, and they could’ve escaped at night?!
Just Another Broken Thing yup,instead,Zara ditched the other 2 so that they could solve the riddle themselves.

Darn that Zara
Just Another Broken Thing Stolen comment
Why would she risk being thrown back into another dungeon, without any knowledge if they could sneak out at night, when she could save herself AND tell the others by leaving and telling them the password through the transmitter?
You are not a perfect logician ;)
Why are they flying at the end? Was it the math and logic?
The logic was there but not in way the simple person would think.
They were enchanted by the narrator.
They are superheros! Listen to the story! ;)
no they ate beans earlier and it came to them
or she asked for the third clue because she knew there wasn't enough info for her compatriots yet. In which case, game over, man! game over!
Or she asked the thrid clue because she didn't have enough info to get out herself after the 2 clues.
Yep
2:24 and look at #4
I like how they just assumed she would just leave them to die the second she had her own way to escape.
Jandalph Well, she's a perfect logician so she should leave whenever she knows the answer and not worry about her friends. So she would leave them to die. Luckily they could escape with her.
1) Went through all possible sets of whole numbers that can multiply to 36 in increasing or equal to order, including ones where the largest number is NOT unique.
2) Found their sums. For the last clue to be needed, that means that there were two or more solutions using the first two clues. The only sets of numbers that this works for is 1, 6, 6 and 2, 2, 9, which both multiply to 36 and add up to 13.
3) The final clue makes it so that 1, 6, 6 does not work. By default it must be 2, 2, 9.
Let's see if I'm right!
I did not watch the solution yet, but I am going to say mine first. I think the answer is 229.
First of all, the first clue is that they all multiply to 36.
I narrowed it down to these codes:
1, 4, 9
1, 6, 6
2, 2, 9
2, 3, 6
3, 3, 4
The second clue was that they all add up to the hallway number you entered. Those sums, in order, are 14, 13, 13, 11, and 10.
The last clue is that the last digit is used only once. The only code I can eliminate is 1, 6, 6, which adds up to 13. If eliminating that code gives her enough information to escape, she must know that the digits add up to 13. The only other code that adds up to 13 is 2,2,9. That is my final answer.
Okay, I am clearly deaf. I thought that there can only be single digit numbers, but the numbers actually can have two digits. But I do not think that would affect my answer at all since none of the codes with two digit numbers in them add up to 13. 229 would still be the only other one.
Gary Lu KOTH
No, you can't have two digits in a single number, you clearly ARE deaf.
Yeah, darn it. What he said in the solution made me think that you can put a two digit number in each slot. So, he made the solution a little more complicated than it is supposed to be.

Alternatively, solve clue 2 last.
The prime factors of 36 are 2, 2, 3, 3.
Clue 3 helped Zara so one of the possible solutions before hearing it must have included one where the biggest number appears twice. The only number we can make appear twice and still be the biggest is 6, in the code 1-6-6. (If 3 appears twice, the other number has to be 4 which is greater than 3.) 1+6+6 = 13, and the only other possible code that adds to 13 is 2,2,9 so this must be the answer.
The number pad at 0:33 threw me off as it only displayed numbers between 1-9, which got me to eliminate 12,18, and 36 as they're divisibles of 36.
In the end, it doesn't matter as the two combinations that add up to 13 both only have the numbers 1-9 in it.
You're allowed to remove them as possible outcomes. I eliminated them as possible outcomes because a numpad lock cannot have double digits. I solved it quicker then because I didn't need to write out or add up extra series of numbers.
True.
lol i paused when he said 8 possible outcomes and i had five so i spent like 10 mins trying to figure out what the other 3 were...

“Concealed audio transmitter”
You planted the damn large thing in her hair.
large? the audio transsmitter just seems 8 inches. how is that big???
Zara could have asked for the third clue in order to provide some extra information to her friends, as she saw that they would not be able to escape using just the two clues they heard, unlike her
I like the riddle, but it has one serious flaw: Zara knows that the other two are going to be escaping based on the information she manages to feed them, and that the first two clues aren't enough to narrow it down for them. So even if SHE could have solved it with just the two clues, she still would have asked for a third one to help her friends, meaning you can't infer the hallway number and the whole thing falls apart.
Exactly. The riddle makes sense for us, but not for the two listening in on the transmitter.
I got it! Yey! I factorized 36, found the 8 combination then noticed the 2 sums of 13. But I thought it differently. If a 3rd clue is needed, then it must be information, not data. Therefore if the correct answer was, let say, 14, the 3rd clue wouldn't be a clue at all. So, yeah, maybe it's not 100% the correct method, but it worked... Still, the explanation is a little confusing since Sarah knew the answer at clue #2 (and the guys would have known that she could already escape). The FACT that she asked for new information (the 3rd clue) is information itself, even though she didn't need to ask for it.
javierr8 except she didn't know after the second clue. Though she of course knew her hallway number, there were two answers where the product of all three numbers was the same as her hallway number (13). So she needed that last clue to figure out which of the two was correct.
"The FACT that she asked for new information (the 3rd clue) is information itself" : Correct. Even if there would have been 2 others numbers that would have summed up to a same number, the fact that she knows after the 3rd clue (knowing the sum) means that the solution that ends up with the square root of 36 WAS considered and now isn't. This tells us in what hallway number she is ;)
I had a similar notion but had missed the information that "if she could enter the passcode now (after clue #2) she would"...and was thinking she was asking for the third clue for the other two and not for herself.
I'll add some hints below. Use them one at a time if you can't solve this riddle:
Hint 1: Try writing out all of the possible combinations of three numbers that multiply to 36 (i.e. 3 + 3 + 4 = 10).
Hint 2: There are eight possible combinations you should have written down.
Hint 3: If Zara had been standing at door 10, she wouldn't have needed the third clue because the code to door 10 would be 334. Which door must she have been standing at in order to need the third clue?
Thank you. I watched the video all the way through and couldn't understand what determined the hallway, but your hints made me understand the premise of their third clue.
This riddle I found it out by myself. The key is zara's change upon the third clue. Without it she can't determine the numbers and with it she can. Since the third clue is "large number is unique" there must be at least one potential situation "largest number in dual or more" suits all former preconditions thus blocked her solving with only 2 clues.
The only combination with largest number in dual is 1*6*6 and that leads to a sum of 13. All other potential solutions must follow this or got crossed out upon the second clue. And that remaining combination is 2*2*9.
