Wait, I think I know (That fast?) That quickly? (What’s the answer~!?) (Q. Which number would go

in the question mark box?) (Dozing off~) (Just blinking his eyes) (Stops momentarily) Is this like a warm-up? [Hyun Moo] Yes, this is a warm-up Wait, this is the warm-up question? We warm up for 1 – 2 hours (The question is

already making us pass out) [Hyun Moo] It’s so draining Wow, how do you solve that? Wh-what? Oh, no (Brainvely is counting the boxes) Wait, I think I know (Already?) That quickly? (What would be the answer~!?) – [Hyun Moo] Holy moley!

– [Kyu Hyun] Ah, I don’t know That was not it. That wasn’t it My heart just sank [Kyu Hyun] We don’t get anything else? – Just look at it and solve it?

– [Hyun Moo] Yeah, you can figure it out (What would be

the rule hidden in the grid?) (Feeling stuffy) I don’t think you’re filing up

the entire grid Isn’t this too hard? This is too hard They gave us extra difficult question

because Kyu Hyun is an award-winning idol (Keeps sighing) (This one’s also sighing here) [Hyun Moo] It’s 5 times 9, right? Looks pretty simple, though I’m just not too sure how to approach it I don’t have any clue! I actually feel better, though,

since everyone’s clueless (Kyu Hyun is starting to get a feel for it) Answer! [Staff] We’ll give you 10 seconds! – [Hyun Moo] Holy Moly

– [Kyu Hyun] Answer! He’s younger but much better than me (Has to solve in less than 10 seconds!)

[Hyun Moo] Park Kyung… [Ji seok] You just solved it

by looking at it? [Kyu Hyun] Yeah Wow, Kyu Hyun is really something – [Park Kyung] Answer!

– [Hyun Moo] What is this?! [Seok jin] We already heard the ding sound You just shouted after

hearing the ding sound – No, no

– [Hyun Moo] Then, what is it? Can I answer it? Can you two say the answer

at the same time? [Hyun Moo] One, two, three 53 [Hyun Moo] Wow! What the heck? (I want to be like them…) [Hyun Moo] Can you show us how you got it? (Kyu Hyun’s showing us how) – [Hyun Moo] Mr. Kyu Hyun!

– I thought it was difficult at first [Hyun Moo] Didn’t he just flip it? So… Try to think of it in a simpler way Since it’s 12… … here, The left is the total number of

boxes on the left And the one on the right is

the total number of boxes on the right So, it’s 22 because there are 2 boxes (Kyu Hyun’s solving it superfast) [Kyu Hyun] 2 and 1 square – [Kyu Hyun] 4 squares–

– Wait, can you explain it one more time? [Hyun Moo] Hey, I’m embarrassed

You’ve been here since the very beginning – [Ji seok] Wait a minute!

– [Hyun Moo] I’ll explain later Don’t ask. It’s embarrassing~ So, the number on the left

is the total number of boxes on the left For the right number, it’s the total number

of boxes on the right [Kyu Hyun] Everything else is the same 6 boxes, 2 boxes 3 boxes, 5 boxes

4 boxes, 4 boxes Since it’s 5 boxes and 3 boxes The answer is 53 (The answer is 53~) [Hyun Moo] Looking at it now That 44 and 22 were big hints Answer! Uh, nope… [Hyun Moo] He really… (His little jokes are making

the emcees nervous) – [Hyun Moo] You freaked me out~

– I didn’t even finish copying it down (Focusing again!) [Hyun Moo] There are eight marbles

Among these, 5 are real marbles 2 have different weights

than the real marbles The real marbles have the same weight, and

the fake marbles also have the same weight And when the marbles were weighed on

the balancing scale, it came out like this Which marble is the fake one? Again, will the fake be heavier

than the real one? (Starting off with a deep sigh) I really hate questions like this… Oh 8! (Moment of realization) (Focused) (Stare) Is the second one the same weight

on both sides? [Hyun Moo] Yes, they are the same (Jang won usually solves problems

at the cost of headaches) What happened to the Number 8 marble? [Jang won] There’s no 8, when they

mentioned there are 8 marbles There’s no number 8 marble (Is the unweighed number 8 marble a trap?)

It must be a trick Answer (Kyu Hyun broke out of his silence) – [What] What?

– [Hyun Moo] What? Are you confident you know it? [Kyu Hyun] I… think… I… am (Confused)

[Ji seok] Is it a definite answer? [Ji seok] A real definite answer? [Kyu Hyun] Definite answer… [Kyu Hyun] I think so Would you bet all your money on it? [Hyun Moo] What kind of question is that? [Ji Seok] Because he solved

it very confidently [Park Kyung] I also got the answer – Can you bet all your money on it?

– Yes – Really?

– I actually don’t have that much [Ji Seok] Is it a real definite answer?

You might be wrong (Continued Interrogation) 100% sure? Park Kyung? If it’s not 100%, don’t even try I give up (Giving up) – [Hyun Moo] Ha Seok jin, the answer is…!

– Yes [Ji seok] I’m ashamed. Give it all you can [Ji seok] What’s your problem [Seok jin] I… I see 1 and 7… are heavy [Hyun Moo] 1 and 7 are

the fake ones and heavy? [Hyun Moo] Why? Just…Just according to my intuition… Yeah, 1 and 7 look a bit bigger, though! Look closely! [Ji Seok] 7 really looks bigger! (Providing unsupported reasons

to find a creative answer lol) [Hyun Moo] But it can be big and be light [Seok jin] They just caught my eye [Seok jin] But it’s wrong. No answer (Seok jin fails, even if he tried

with his eagle eyes) [Hyun Moo] He said all this nonsense

since he was rushed [Hyun Moo] Then, Park Kyung… [Hyun Moo] Kyu Hyun! [Hyun Moo] Say the answer at the same time! [Hyun Moo] One, two, three! Number 3 and 7! [Hyun Moo] 3, 7? – [Hyun Moo] Then, Mr. Kyu Hyun!

– [Kyu Hyun] It’s my turn? Wow, amazing [Kyu Hyun] It’s because 4, 5, 6 are the same marbles [Kyu Hyun] In here, [Kyu Hyun] only real marbles exist – Why?

– Why? [Kyu Hyun] Because here, it’s heavier [Kyu Hyun] In here, assuming that a

fake marble is included Not sure if it’s one or two But wait! How are you sure

that the fake marble is lighter? [Hyun Moo] You’ll have to guess whether

it’s lighter or heavier [Kyu Hyun] Ah, it’s heavier! – [Hyun Moo] But how do you know that

– [Jang won] Why, why? [Kyu Hyun] So, first if we assume that the fake

marble is heavier the fake marble will be here It’s either one or two [Kyu Hyun] And since it’s here [Kyu Hyun] Anyways, in here [Kyu Hyun] Among these, 1, 2, and 3, [Kyu Hyun] there’s 2 and 3 [Kyu Hyun] and there are 4, 5, 6, 7 (Kyu Hyun sounds right…) [Kyu Hyun] So since there are one or two

fake ones here, I assumed on the 2nd balance,

there would be a fake marble on each side [Kyu Hyun] This Since there’s a fake one here There’s 7 here Then, for here (3,7 are heavy → 2nd

balance can be made into an equation) Since 4 and 2 are most unlikely As well as 1, so I thought it was 3 Do you get everything he says? Is that how you solved it as well,

Park Kyung? [Hyun Moo] Park Kyung, Go! (Park Kyung will show us how to solve!) [Hyun Moo] Geniuses have their

own solving methods – That’s why he can’t explain to us

– [Park Kyung] So, when you look, 2 marbles have different weights,

but those two have the same weight But when you look at the second balance,

the two sides have the same weight Then, we can get 2 scenarios [Park Kyung] When 2, 3, 4 and [Park Kyung] 5, 6, 7 are the same, 1 or 8 are fake ones, or each side has a fake one Right But when you look at the balance 4 and 7 (3rd balance should be even) [Park Kyung] 4 and 7, – [Hyun Moo] 2 and 6

– [Park Kyung] And there’s 2 and 6 [Park Kyung] these two are different Right, but when 1 and 8 are fake,

the two should be the same Since 1 and 8 aren’t included, all of them will have the same weight,

4, 7, 2, 6 But since there’s a weight difference,

1 and 8 are the real ones [Park Kyung] So then,

there’s a fake one for 2, 3, 4 and for 5, 6, 7 for sure [Hyun Moo] Yeah yeah yeah I chose it like this because there’s no 7 On the above, there 1, 2, 3, 4

on the bottom, there’s 2, 3, 4, 5, 6 But 7 isn’t included So, thinking 7 is the fake marble I thought 3 was also fake So, I said 3 and 7 [Hyun Moo] 3 and 7 are fake marbles (Kyu Hyun and Park Kyung got it right) [Hyun Moo] It’s heavier? The fake ones are heavier? – [Hyun Moo] The fake ones?

– [Kyu Hyun] The fake ones are heavier [Park Kyung] Since the side

with 1, 2, 3 are on the bottom 3 is the heavier marble

MAN I GOT IT WITHIN 1 MINUTE OMG MY BRAIN FINALLY WORK STARTS FROM TODAY

My brain hurts

Kyung 😍

Geniuskyu is here!!!! And i dont know park kyung but he's amazing as well! Uri maknae definitely has bragging rights. Hwaiting!!

Everyone : 🤔🤔🤨🤨😮😯😀😀😎😎

Me:🤔🤔🤨🤨😵😵🤯🤯

I don understand at all 😅😅

He's smart here but dorky in journey to the west 🤣🤣🤣

이건 나도 품

문남에서 이번 2문제 처음으로 다 맞혔다 ㅠ 2번 문제 해석이 이상해서 덧붙이자면 나는 1.2.3 과 4.5.6.이 무게가 다르고 1.2.3.이 더 무거우니 3개중에 2개는 무게 1로하고 나머지 한개는 무게 2로 가정해서 몇번 해보면 끝

Kyuhyun's explanation to the second problem seemed easier to understand. 😊

It’s cute how they kind of look alike too

Super junior's Sexy Brain ❤️

Can someone tell me what episode is this?

Kyukyu is here… kyuhyunie and kyungie!

박경 설명에서 4,7번이 더 무거운거 아닌가요?ㅈ ㅓ울이 내려가자나요

I'm with honors but why do I feel dumb?? 😭😭

I'm with honors but why do I feel dumb?? 😭😭

I wish I had Kyuhyun as my math tutor back in my high school days

So funny. Both of them explaining… Still don't get it… Nyahhahahaha

Sometimes, the most complicated problems are the easiest ones to answer.

That's how Kyuhyun and Park Kyung taught us in this specific clip. Why complicate things when you can simplify it? 😉

유효선님 제 말이 맞는듯요 자막에선 그렇게 표시가 나옵니다 4,7>2,6이라고요

LOOK AT MY BBY PARK KYUNG GO !!!!!!!!!!! 😭💗💗💗💗💗

kyuhyun my 🍯

Finally, after wait a long time, engsub come. Thankyou TVN, please do for another video(problematic men).😌😌

The marbles one is the first I solved correctly 😂

I solved the first problem in 20seconds😃

네모네모로직을 많이 해서 그런가 바로 보이네

이번화는 나도 다 풀었다 뿌듯 ㅋㅋ

been watching loads of these the last two days and I'm proud (yet also kinda sad) to say that marble question is the first one ive managed to solve myself XD

7:32에 박경 부호 반대로 썼네요

ihavaheadache

Damn i still dont get it.. i should leave the earth..

Kyuhyun en muy inteligente! Realmente le gustan las matemáticas, lo amo

So basically what i learned is that "kyu" is only for smart people. Got it.

Indeed, Kyuhyun is tvn's son 👏

규 집중하는거 멋있어ㅠ_ㅍ

I'm up bro😂

Wow I'm genius. I guess that correctly within 1 minute.

I feel like I'm the most stupid in the world. Feeling insecure yet proud of my baby Kyukyuu ♥️😻💙

KOK BISA ASTAGA MEREKA EMANG PINTER BANGET😭❤️❤️❤️

Haha I still don't get it XD

Am I this dumb??? Lol

I was like kyu haha, when I solved the marbles in my head it made sense 100%, but when it came to trying to recall and explain the exact way i arrived at the marble numbers it became a jumble lol. And it's funny how now knowing the answer clouds the mind more about replicating the process. But I'm pretty sure Kyu also solved it like Park Kyung and that's also how I did it (starting with the middle scale, then the bottom one, and then eliminating scenarios one by one though he didn't explain up to the end here). I actually paused to figure out how I solved it again.

So lucky the woman he loves😍

What's the title of this show??

Lol i did not understand everything

Kyuhyun daebak

i love the reggae background.haha

I don't get the solution for the 2nd problem…. help

규현은 자기한텐 너무 당연한 얘기라 설명을 안해도 된다고 생각한 거임… 똑똑해..

I had 53 as my answers toooooo

I didn't understand anything😂💔

I know Kyu since I was in middle school, back then I used to brag a lot about how smart he is. I'm a senior college student now and I'm still so proud of him, I admire him a lot. I still think about him whenever I have a math exam 😂💙 Watching him again on TV shows gives me so much happiness and strength! Before his enlistment I didn't follow him or his activities as I used to when I was younger but I missed him so much that now I'm a full-time gamer again! 💙 Support this big baby a lot, please! He still has a lot to show!

Cracked problem

53, it's so easy actually. But it's confuse u when u first look at it

Kyuhyun my luv

We want to see Ngamon in your program for only one time

Siapapun yg jadi istrinya Kyuhyun nantinya, pasti luar biasa diberkati. Dapat suami yg udah pintar, cakep, tajir, suaranya bagus pula. Kurang apalagi coba😂😂😂

Man with brain always the sexiest..😊😊

Stan idol with brain..😚😚

I solve the number 1 in 5 minutes but just when i read the second question i give up haha

Kyuhyun marry me!!?

This is what is fun with math and logic, you may start and solve in different ways but you still arrive at the same answer.

my head hurts watching this

At first, I can't understand Kyuhyun. But, when Park Kyung explained, I relate the explanation from Kyuhyun to understand Park Kyung.

I seriously got the marbles answer of 3 and 7 Correct!(I surprised myself) :OI've paused the question and solved it like this:

> in 3rd balance, since 4,7 weighs heavier than 2,6 it must definitely contain at least one heavy marble which are fake (since out of 8, all the remaining 6 are of same weight are real)

> in 2nd bal, I've arrived that since the middle balance is equal, it must contain at least one heavy marble each side (since both 7 and 4 is on either side, so to balance other it definitely needs other heavy one)

> Finally, in 1st bal, if 4 was the heavy one (from 3rd balance) it would go down, but it stayed on upside, meaning it is not heavy! So, obviously 7 is the heavy one!

> Therefore, it's either 2 or 3 will be other heavy ball, but since in 3rd bal, 2 is on the lighter side along with 6, 3 is the other heavy ball!

경희대생 짱 멋이ㅛ어 아니 ㅠㅠ 개발려

Which ep is this?

Wow i actually answered faster than them! I can't believe myself :3

아싸 다 맞췄당

……..뭔…소..리… 야…?

While on the other hand I am (we are?) here

Don't understand Korean

Don't understand (simple) Math (even in our mothergongue(s)

still watching strangers solving ridicolous riddles.

mis dos bebes juntos Park Kyung y Cho Kyuhyun <3 Realmente esto es genial

MEN D MAN TO TINUTURO SA SCHOOL NAMEN EH WTH ARE THESE

문제풀이 4번 돌려보곤 이해됬다..

빡대가리라 보면소 한문제도 못풀어봤다

1 2 3 > 4 5 6

2 3 4 = 5 6 7

4 7 > 2 5

Eyy it's really a warm up question. Why they can't solve the real easy question fast but can sold the hard one faster 😑 it's just counting the square.

계속 이프로그램을 보니까 조금씩느나.. 30초만에 풀었네..

박경 규현처럼 생긴상이 머리가 엄청좋구나

와 나 한 1분만에 맞힘 기분 짱좋

i'm asian, too.why the hell did i failed college algebra gosh i envy themi like how kyuhyun explains it in a simpler way,

but kyung is more detailed on explaining complex maths아싸~가짜구슬 문제 정답 맞췄다!!!

i can also solve all the questions, but unluckily i need more time than kyuhyun and park kyung.

So annoyed at how Problematic Men have to be on hiatus ZZZ 😑😑😑 love this show but no new episodes now CRI 🙁

im dizzy..

Awww my head 😣😂😒

와.. 나 1분 40초만에 풀어버렸다.. ㄷㄷ

와 나 1분안에 바로 풀음 대박 처음이야

I still can't understand the marbles thingy even after Kyu's good explanation. 😂

Im very poor when it comes by solving numbers to make the story short i hate mathematics…but maybe if my math teacher is KYUHYUN maybe i will be smart….smart enough to realize that i like him 😂😂😂😂

내 머리가 아픈데 내 눈이 너어어무 반짝 반짝 별 처럼ㅋㅋㅋ 규현이 때메 ㅋㅋㅋ 뭐야 -..-

I suck at Math, if only kyuhyun was my tutor husband. 😢❤

What episode?

I knew his good at math 😊

50문제 풀다보면 가끔 바로 정답이 나오는 문제가 나와서 행복 ㅋ

Omg.. Finally one question i can answer 🤣🤣🤣
