## If You Solve the Riddle, You Can Become a Secret Service Agent

Ever fancied becoming a real-life spy? Or maybe an astronaut? Or perhaps you want to work for one of the

biggest IT corporations in the world? Then you’ve got a chance to test your mettle

and see if you’re witty enough for any of these jobs! The spy riddle

British National Cyber Security Centre, or NCSC, disclosed a riddle for their potential

high-profile employees some time ago. If you’re able to solve it, then your mental

abilities are enough for you to become a cyber-spy! Let’s check it out, shall we? The riddle goes as follows: “Thirteen rotters

stole my answer and they ROTated it by 4 and then ROTated it by 10 and all I have left

is Uccr ziqy hc ozz QmpsfTwfgh Uwfzg! — (well you can read this for yourself). Can you help me get my answer back?” Everything in this riddle is right where it

should be; there are no mistakes or typos, so take your time and try to solve it yourself. Don’t be in a hurry — just pause the video

if you don’t want to see the answer right away and turn it back on when you’re ready

to check yourself. I’ll wait right here, don’t you worry. So, you’re here again, and I take it as

a cue to start my explanations. But first, I’ll give you a little hint:

the riddle uses the so-called “Caesar cipher,” which scrambles the letters in a certain system. You’ll need to toss them around (like a

Caesar salad) c using the alphabet, that is, each letter is shifted to a number of positions

back in the alphabetical order. For example, if the key is 5, then F will

move 5 positions down and become A, and so on. Got it? Then why not try again if you didn’t manage

to nail it on your first attempt? I’ll wait here again! Okay, now the games are over and we’re heading

straight to the solution, so listen up. First, fetch the alphabet on the Internet

or just write it out. Now look at the first letter in the code message. The riddle says that the rotters ROTated the

answer by 4, so make it 4 positions down the alphabet and you’ll get Q. Then it says

they ROTated it again, this time by 10, so without any complex ideas just count down

10 more positions, stopping at G. This is your final point for this letter. Then do the same operation with each of the

letters, and you’re cool as cucumbers! In the end, you should get the following phrase:

“Good luck to all CyberFirst girls!” Not that hard, if you think about it, but

only if you had the key from the start. If you didn’t listen to my hint and still

managed it on your own, you deserve a double praise — you’d definitely do well in a

cyber-intelligence test! Now, the “thirteen rotters” and the capitalized

letters ROT might’ve confused you, but they’re simply a distraction: it’s a reference to

ROT13 — another cipher that switches letters with those 13 positions up the alphabet. Feeling good about yourself yet? Well, it gets better! Here we go… The astronaut riddle

Tim Peake, a British astronaut, posted a puzzle on his Facebook page, claiming it was from

the test he had taken himself when applying for a position in NASA. Obviously, he’d solved it, but can you repeat

his feat? Let’s find out! Imagine you’re facing a cube. It can roll to the left, right, forward (towards

you), or back (away from you). On the bottom of the cube, there’s a dot. Now roll the cube forward, left, left, forward,

right, backwards, right. Where’s the dot now? Again, don’t be in a rush and pause the

video to visualize the whole thing carefully. You’re applying for an astronaut, for cake’s

sake! If you’re hearing me now, then you’ve

probably solved the puzzle or are just waiting for the correct answer. Either way, here it is: the cube will end

up in exactly the same position it started from, so the dot will be on the bottom. Check it out for yourself if you don’t believe

me! Okay, ready for some other kind of mind-bending? Here goes… The Facebook interview riddle

If you ever wanted to work for the social media giant, check out the question they used

to ask their candidates at an interview. Would you be able to pass the test? You’re about to board a plane to Seattle

and you’d like to know if it’s raining there. You call three friends from the city and ask

about the weather. Each of them has a 2/3 chance of telling you

the truth and 1/3 chance of lying to mess with you. All three of them tell you that it’s raining,

though. What is the chance that it’s actually raining

there, considering that neither of the three knows the others? It’s more of a mathematical problem, but

it’s how Facebook tests their future employees, so turn on your math brain! Ready? Then I’m going forth with the answer. You could guess all you like about the odds,

but the easiest way to find them out for sure is to add them up. Suppose all three friends lied to you. The probability of that will be 1/27, that

is, 1/3 multiplied by 3. That will be the chance of it not raining

in Seattle because all of your friends told you it was. So the probability of it actually raining

is 26/27, or 96%, and it could only happen if at least one of them told you the truth. So did you get this one right? Let me know down in the comments! And next up is… The Google interview riddle

If your brain is ringing from all the math stuff, relax — this one doesn’t have to

do with any calculations. But it doesn’t mean it’s simple! So listen up. Why are manhole covers round? If you can give the answer right away, then

just continue watching this video! Ready to check your guess? Good! They’re round for two reasons: first and

foremost, a round manhole cover will never fall into the hole, whatever side you put

it down. And secondly, it’s easier to roll to the

site. But even if you only guessed the first part,

you’d already land the job at Google! Congrats! Going to the next one… The Apple interview riddle

Now this puzzle is going to blow your mind, but don’t get too rough on yourself — after

all, it’s not like you’re gonna really get the job at Apple after solving it, right? Anyway, here’s the deal. There’s a table with 100 coins lying on

it. 10 of the coins are heads up, while the rest

of them are tails up. You only know it, though, but can’t see,

feel, or find out in any other way which ones are flipped. Your task is to split the coins into two piles

so that there’s the same number of flipped coins in either pile. Remember, you have all time in the world if

you just pause the video to think. So, did you get it? Even if not, I’m gonna explain this to you. You know why it’s mind-blowing? Because it’s so simple you won’t believe

it. You just need to take any 10 coins from the

table — and I mean any, — make a separate pile of them, and flip them. That’s it, you’ve solved the puzzle. It doesn’t matter if there’s one or two

heads-up coins in your second pile or not. In fact, it doesn’t matter which coins you

chose in the first place. If you take them from the initial hundred

and flipped them, you’ll get two piles with the same number of heads-up coins in both,

no exceptions. Wanna check it out for yourself? Just try! If you’ve finished experimenting, then there’s

the last riddle waiting for you. Ready? The LinkedIn interview riddle

This one is probably the most difficult, and I don’t expect that you’ll give the correct

answer. You’ve been warned. So the question is… How many golf balls would fit into a Boeing

747? Do you know the solution? If you need time to think, you know what to

do. And if you don’t want or need any time here,

I understand you perfectly: it seems simply unfair to ask such a question. And it actually isn’t! You see, if you’re asked something like

this at a job interview, there’s a catch: the hiring manager doesn’t expect you to

give a definitive answer. In fact, they might not know it themselves! What they need is to see your brain at work. So if you eventually find a solution, make

sure to share it in the comments with all the reasoning and calculations behind it! After all, they’re the most valuable asset

in this test! Hey, if you learned something new today, then

give the video a like and share it with a friend! And here are some other videos I think you’ll

enjoy. Just click to the left or right, and stay

on the Bright Side of life!

So, guys, which of the riddles did you manage to solve? ๐

I think the last riddleโs answer is 747

1 lakhs ball .less means balls are fall down from airplane.more means balls come from golf ground……

23.5 million golfballs

who else used google search? xd

I think 23 and a half milligrams cause I did the math the boing 747 is ….. meters and a golf ball is ….. cm and do it all together it will be 23 and a half million

I did the riddle right I am coming NASA and Google

Google isn't an IT corporation so get your facts straight

The answer is infinite

Actually does't 1/3 * 3 =1? Not 1/27. 1/3 cubed equals 1/27.

1/3 ร 3 = 1/27 ???

Shouldn't it be 1?

""GOOD LUCK TO ALL CYXERFIFST GIRLS"" Almost got it

More then one golfball

Got the second one HAHAHAHA

I dont get the third one :<

I solved first four riddles

Sisi terang anjay:'v

I think is:The amount of golfballs it takes to fit in the 747

I answered all but still jobless!

there can be 747 golf balls in a boeing 747 because it says so in the name lol

Doodoodoodoodoodoodoodoodoodoo

I solve the golf riddle ..

I'll tell the interviewer it's 23.864 million balls ….

He will ask how do know I'll ask him too how can you sure that my calculation is wrong even you don't know about that…

my answer is you can put 100000000000000 this much ball, if you dont believe me just go and try to put balls and prove

me wrong……….

Who came to the comment section to see the answers

we can just put as many balls that fit in the aeroplane

I think its 3000 or 7000 on the last one

I'd say no golf balls because you wouldn't get them past security

747 golf balls

Abcdefghijclonmpqrstuvwxyz is the alphabet

7,509 this is because i measured it

Sorry i didnt learn alphabets backwards

This Code in th Thumbnail has No meaning

My Answer for the Last one:

Sir, "There is Even ONLY ONE Golf Ball will FIT into the AirPlane. If You want to FILL with more, Count each on of them to FULFILL your Wish."

Thank You.

(Awaiting Linkedin Interview :-))

There is 747 golf balls

๐๐๐๐

235000000 ball will fit into a Boeing 747

I say even one can fit in the airplane as the question is 'how many golf balls can fit' not the total number.

Chinese 3rd graders: What's these? We do these for extra credits.

– How many golf balls would fit into a Boeing 747??

– 27 million…

– how do you know that?? any proof??

– count it yourself…

At 5:35 you state that 1/27th is โ times 3. That is incorrect. It should state that 1/27th is โ cubed.

All the ridles can be solved

If they put the answers :v

1. good luck to all CyberFirst Girls! 2. Bottom. 3. 96% is the answer, but as usual, these questions have more than one answer. Te right answer is 100%, because if these people are actually my friends, then they have no reason whatsoever to lie to me. It's raining there… 4. A "Man-hole Cover" is Round so it can't fall in the hole. 5. Flip over 10 coins. 6. It doesn't matter how many golf balls will fit into a 747… Why would you even do such a thing. I am trying to get a job, not beat my head against a wall trying to calculate something that has no value to me or the job I'm trying to get.

There can be 106.725.105,5 golf balls in a Boeing 747. A golf ball is 77.690,502163 millimeter^(3). And a Boeing 747 is millimeter^(3).

The calculation: 8.291.527.040.000รท77.690,502163=106.725.105,5

Roartared ๐คฆ๐ผโโ๏ธ

Are you a cat?

Maybe…..

I got them all right.

Solvedโค๏ธ

The whole-cover wonยดt fall into the whole not because itยดs round, but because itยดs recessed or chamfered.

it's 18,695,360

a round 23,500,000 golf balls will fit in a 747

23.5 million golf balls would fit in a Boeing 747 ๐คฏ

Assuming the plane is a 747. and the diameter of the golf balls is 40mm. 23.5 million balls would fit in the plane.

more than one

i got all right so whats next give me harder riddles

I knew that. It's too much work. If I was stranded and had to I would

the answer to the last one: 23.5 million

edit: im a cheater

The answer to how many golf balls could fit in a boing 747 is 23.5 million golf balls.

the answer is there would not be golfballs in a plane haha

Yeah….I regret re-watching this channel.

1.) So they won't fall through

2.) They are easier to transport or roll

3.) It uses less metal when it is being made.

why is he saying rooattaeded it

or something like that.

alright, the volume of a boeing 737 is about 40000ft cubed and the circumfrence of a golf ball is about 5.3 inches squared. And 40000ft in inches is about 480,000in, so 480,000 divided by 5.3 is 90,566. So 90,566 golf balls will fit in a boeing 737

There are 1000000000000000000000000000000 golf balls

the dot will be at the back side of the cube not at the bottom

Iโm 10 years old and I got this in under five minutes it was so easy and Iโm going to give two of my friends and my teacher to see if they can get it correct I feel that if they donโt I will laugh but not at my teacher because I might get in trouble

Face reveal

Just life gravity falls!

three letters back800,003,789 golf balls as we divide the area of golf balls to the area of the boing 747

I solved the astronaut one and the Google one๐๐

I like the way he says, "gooood"

Why would we ship air, let me find a rail or sea rate with an freight forwarder and save the company at least 30-70%, with the extra profits we can send clients gifts and flowers for their patience with new shipping times and give them slightly cheaper rate.

Who's in?

i managed to solve all of the except the first one in starting but after u gave hint i could amazing

The golf balls in the 747 I'd say about 23,502,369

Thanks for posting this video. I now work at Apple's headquarters.

The answer is 25.5 million

last one: 23.5 million golf balls

Last question's answer:

More than one

The reason is:

Because it's true

๐๐๐

747

how many golf balls in the Jumbo ? answer is simple. no quantum -"TOO MANY "" !!!

U forgotten that the manhole covers are cheaper as if lets say a square with sides 1m the area of it will be 1m2 but if the radius of the circle is 0.5 the area will be 0.785m2

Hence round manhole covers are cheaper

Yey im an astrounot

We need just one ball which is as large as the plane is.

8:29 The answer: More than 3.

Who here thought of matpat while solving the riddles

all of them

and the last answer is a lot because the Boeing 747 is big

10,000

Yes got it!

The astronaut riddle was Wrong,the hole was on top

If you do Caesar cipher then Rot+14,the code in the thumbnail means CYBERFIRST GIRLS.

The explanation of the facebook probability problem is just wrong: 1/3 * 3 equals 1 and not 1/27. What you mean is 1/3 * 1/3 * 1/3 = 1/27

The ceaser code goes up not down

LinkedIn question

Answer

The answer is zero if none of the pilots or flight attendants like to play golf if the plane is filled with golf players then u must think and take 2 golf balls per seat as 1 is to play and the other is extra so then u must multiple the no of seats multiplied by 2 .

1. The plane he talked about was a commercial airline not a luggage carrier plane or corgo plane

2. You must take the no.of seats acquired by the passengers for example

There are 420 seats and only 360 are reserved and the rest vacant so ya

3. If the the flight is filled with golf players like 420 out of 666 seats and each carry two carry two golf balls and if the flight gives 1 extra as token of love then add 2 and one u get 3 so multiple 3 times 420 that's the no. of golf balls

4. It is a commercial airline and the don't simply put golf balls and waste their time cause they must be ready quite quickly to fly so there is no time for them to fill the plan and remove almost all balls from the plan.

OK bye that's all for today pls pin this comment so others know how to answer the question properly.
