In this dystopian world, your resistance

group is humanity’s last hope. Unfortunately, you’ve all been captured

by the tyrannical rulers and brought to the ancient colosseum

for their deadly entertainment. Before you’re thrown into the dungeon, you see many numbered hallways

leading outside. But each exit is blocked by

an electric barrier with a combination keypad. You learn that one of you will be allowed

to try to escape by passing a challenge while everyone else will be fed to

the mutant salamanders the next morning. With her perfect logical reasoning,

Zara is the obvious choice. You hand her a concealed audio transmitter

so that the rest of you can listen along. As Zara is led away, you hear her footsteps echo

through one of the hallways, then stop. A voice announces

that she must enter a code consisting of three positive whole numbers

in ascending order, so the second number is greater than

or equal to the first, and the third is greater than

or equal to the second. She may ask for up to three clues, but if she makes a wrong guess, or says anything else, she’ll be thrown back into the dungeon. For the first clue, the voice says

the product of the three numbers is 36. When Zara asks for the second clue, it tells her the sum of the numbers is the same as the number

of the hallway she entered. There’s a long silence. You’re sure Zara remembers

the hallway number, but there’s no way for you to know it, and she can’t say it outloud. If Zara could enter the passcode

at this point, she would, but instead, she asks for the third clue, and the voice announces that the largest

number appears only once in the combination. Moments later, the buzz of the electric

barrier stops for a few seconds, and you realize that Zara has escaped. Unfortunately, her transmitter

is no longer in range, so that’s all the information you get. Can you find the solution? Pause on the next screen

to work out the solution. 3 2 1 You’re worried about the fact that you

don’t know Zara’s hallway number, but you decide to start

from the beginning anyways. From the first clue, you work out all of

the eight possible combinations that come out to a product of 36. One of these must be right,

but which one? Now comes the hard part. Even though you don’t know which number

you’re looking for, you decide to work out the sum

of each combination’s three numbers. That’s when it hits you. All but two of the sums are unique, and if the hallway number had matched

any of these, Zara would have known the correct

combination right then and there without asking for the third clue. Since she did ask for the clue, the hallway number must have

matched the only sum that appears more than once in the list: thirteen. But which of the two combinations

that add up to thirteen is correct: 1,6,6, or 2,2,9? That’s where the third clue comes in. Since it tells us that the largest

number must be unique, 2,2,9 must be the code. When night falls, you and the others

escape through hallway thirteen and rejoin Zara outside. You’ve freed yourselves through

math and logic. Now it’s time to free

the rest of the world.

Everyone try to make a JavaScript code copy of the passcode riddle!

Why not 149??

Guessed 229 from the start bc it was the only one I could be bothered to work out would multiply to 36

I didn't think about the other possibilities, I just did 229 and got it right xD

They would be doomed if she just left after two clues

I thought X,Y,Z each of them in range (1 to 9) =_=

The first clue didn't make sense to me :))))

"Zara, a perfect logician, needed clues 1-3 to escape" LOL

Couldnt they just fly out?

I L I K E P U M P K I N P I E !

zara looks cute

Just beat the dungeon

Wow! I can't even solve an easy riddle 😀

I actually figured this one out.

Greatest achievement of my life

After so many riddles, atlast I solved one

“Your resistance group is humanity’s last hope. Unfortunately you have all been captured”

Shows three people getting kidnapped. Hmm yes “GROUP”

Video fatto bene e gioco divertente

Easy

“Concealed”

puts a giant stick in her hair1:22 I know this is mean but SKSKSKSKS that scream

Zara must enter the passcode.

Wut I actually solved it

i literally solved it in 5 sec, not even lying

The 2.3k dislikes are from the people who would fail us all or didn't even understand the riddle even when they were wrong

"Can you solve the passcode riddle?"

Awkward silence…

Ummm…

noI'm the last hope? Well then humanity? Dead. Aliens? Happy. Salamanders? Full. Hotel? Trivago.

If they had superpowers couldn’t they have just used their powers to escape?

I actually got this one

i'm no native english speaker, why the sum =13 appear twice is unique?, and how is that related to second clue?

1. Confirm that you have green eyes.

2. Ask the tyrannical rulers to leave.

I got it using only clue 1 and 3 just by chance it was correct

2x2x9 would be 36 though

Holy mother of Jesus I just guessed 2 2 9 because it was the only solution I could work out

Ummm… I'm pretty sure that the passcode pad only had one-digit numbers… So shouldn't that ALSO eliminate some possibilities?

So easy tho

i just did 1 multiplicatiion problem and it was right LOL

0:51 (CONCEALED.)

Yay I got it right

Such a bad scenario, you won't even win but only survive

11

But they say it must be in ascending order! How can 2<2 ?😶😑

yes i got it.

That transmitter is not very “concealed”

Omfg I actually got this one. It is 10:30 right now and I am binge watching TedEd riddles. Lol.

This was the easiest riddle in the Ted-Ed library and I still can’t get it

Ayyy I actually got it

The code isn’t a series of numbers and it’s the words I like pumpkin pie

Guy: your resistant grou…

Legendary: do you see my existence?

Stops at door 42Intuitively I already new that the answer was 229

I did itttttt

I thought Zara just asked for the 3rd clue so she could help the other 2 out, not because she didn’t yet actually know

But i really like pumpkin pie…

229

Nobody:

Zara: I LIKE PUMPKIN PIE

4 out of 43

Zara is a traitor

The advance version of 7 second riddles

Me: (solves riddle and escapes with teammates)

Us: (get captured and are about to be fed to the giant lizards)

Me: FML.

The animation is so COOL UWU

2 2 9

This is the only ted ed riddle yet that i solved myself. 😅

it’s 229

OMG I ACTUALLY FOUND IT

These riddles are hard

Is it 2 2 9

When you are super proud that you just solved a riddle but then see in the comments that this was supposed to be the easiest😑

1:22 oh no bye bye back to the start

Lets suppose code was 1 4 9 and Zara got it with the second clue, but still asked for the third to help you out? I think the riddle has its flaws

I FINALLY GOT ONE BOIS
