There is another correct answer to #5. It is possible to transfer 1/2 a barrel from a full barrel to an empty barrel. The barrel is cylindrical and symmetrical. If you pour such that when you finish, the barrel is tilted such that the surface of the oil remaining in the previously full barrel touches the top of the joining of the bottom and side of the barrel, and the bottom of the lip at the open top, the oil will occupy exactly half of the barrel and you will have transferred half the oil. When the pour is finished (while the barrel is still tilted), the surface of the oil will define the plane through the cylinder that defines an ellipse with the longest possible axis. After transfer of 1/2 barrel from a full to an empty barrel, the problem is easy.
And BTW this solution requires less work than that in the video. 👍
This is also how I got the solution, I was confused why he didn't mention it because he's made a video with a similar solution for seeing when a cylinder is filled halfway.
I didn't think about this logic when I solve the puzzle, but it is also a possible answer. Each sons will get 7 half barrels, 0 full, and 0 empty, so it's still equal. However, it does require more work for the merchant since they have to pour 7 full barrels into 7 empty barrels to make 14 half barrels, whereas combining 4 half barrels into 2 full barrels is so much easier
I've worked in IT for over 25 years (as a systems analyst, web developer, and software architect) and have never been asked any sort of logic question during an interview. On a related note, I got a perfect score on the logic section of the GRE so there's that...
In the oil and barrel questions we do not need complications with oil distribution, because its also the barrels that need to be distributed evenly.
There are a total if 21 barrels, thus everyone gets 7.
So, the first two sons get each 3 full+3empty +1 half
And the third son gets 1full+1 empty+5 halves
Are you serious? I mean, what kind of father are you?
You give your first 2 sons the good and full (unopened) barrels, and the 3-rd son gets 5 halves? And you know the oil quality is not the same if a barrel has been opened. 😁😁😁
I'm kidding of course. 😁 Your solution is valid. My point was: whatever you do (as a parent), there will always be someone not happy with your decision.
@@ciberiada01 exactly... Always a valid & correct answer should be Posted..
On #4, in reality, just setting your clock to noon at the closest you can approximate noon via shadows would probably be more accurate than assuming you actually walked at a consistent speed and know the travel time precisely.
No it's not easy to approximate noon by seeing shadow.
Because sun travels from tropic of cancer to capricon, hence it may not pass just over your head.
You may also need compass for it
@@manusarda
Well, assuming that at noon the sun is at its peak (it drops the shortest shadow), these methods are not really difficult.
The rest is just a question of finding a water vessel and punching a tiny hole in it. 😁
@@ciberiada01 I didn't understood what are you saying by water vessel and hole.
Regarding the noon part, you are correct (shortest shadow).
But at my place, shortest shadow will be ar 1:00 PM because I live in Jaipur (city in India). There is 2 hour difference between eastern and western point, whereas the time zone is set with reference to Kolkata.
So if you live in India then this method will work only in selected cities (which are on same longitude with kolkata).
Situation get worse in Russia.
@@manusarda
Ah, Russia! 😁 They are always hard to deal with. (Joke)
I'm glad to meet someone from India! Greetings! As for the time zones, yes it's true they never follow exactly the ‘astronomic time’. But even if you're in the farthest city, the max. difference will be about 1h, let's say 1h30. Which is preferable, compared to not having time at all.
➡ To your question, the vessel and the water were for making a kind of a water clock. If you leave the water to flow from one noon to the next, and you divide this quantity by 24, you will get approximately the duration of 1 hour. (I imagined I'm Robinson Crusoe in a desert island. 😁)
@@ciberiada01 changing water level will change the pressure which will change the rate of outflow.

Riddle 5 in a better solution:
2 x( 3 Full, 1 half, 3 empty) and 1x( 1 full, 5 half, 1 empty)
nice one but in the question they said that each person should get same number of full barrels, same number of half full barrel and same number of empty barrels
Great you are!
In the 2nd Puzzle I created a general formula for each sheet. So sheet 'n' would have page numbers 2n-1, 2n, 400-(2n-1), 400 - (2(n-1)). I still got the correct answer, but your method was ingenious.
The legend is that Gauss came up with this as a child. He was assigned to add the numbers from 1 to 100. Gauss did 50x101=5050.
same bro.
Here 178 can be 2n or 400-(2(n-1)), either ways, we get the same answer

Welcome to channel :)
#5 you can’t empty a barrel completely as there would still be oil remains in there. Therefore the empty barrels by default are more empty than the two emptied barrels. One son still doesn’t get justice 😾
it's clearly shown in the video, the barrels are supreme quality and oil repellent 😬.
Itna dimag puzzle solve karne me lagata toh answer mil jata
@@manusarda Answer to kab ka mil gaya tha 😂
you can eliminate this issue by 1st transferring oil from all of half full barrels to all of empty barrels & then follow the procedure as shown in the video, if u dont want to accept the fact that the barrels are of very high quality & oil repellent
And you know the oil quality is not the same if a barrel has been already opened and half empty. 😁😁😁
I'm kidding of course.
I literally answered 2nd question but it in different ways, I too the addition of every page number on the respective sheet, which accounts for 802.
Yes, you can come up with 178/223 with the one piece of information, but you are stuck with having to make a choice between 177/224 and 179/222 which would be the adjacent pairings to 178. You need the added knowledge that an even number, like 2 always is the back side of 1, a lower number, so in this case 178 is the backside of 177.
Riddle #2, I answered thinking outside the box: The answer is "yes". It was never mentioned to say which were the other page numbers.
That's genius
Hat's off to Sir, your puzzles are amazing and your explanation is the
highlight of the presentation.
Woww this time i was able to solve all 5 of them otherwise your riddles seem very hard to me

Barrels and oil solution without transferring:
1st: 3F+1H+3E
2nd: 2F+3H+2E
3rd: 2F+3H+2E
everyone has 7 barrels
everyone has 3,5 barrels of oil
It said that everyone has to have the same number of full, half full, and empty barrels though, so that solution doesn’t work
kya baat h bhai bahut badiya
5 riddle. Transferring from Full to half makes sence. I've transferred full barrel to two half filled twice and it solved the riddle.

1:00 is the time he recognized, that his fence is not square and the solution would not work this way.
Define square
@@niconicer6463 A square is a rectangle with equal side lengths.
I dont understand this comment, I even went back and checked the video but his fences are square.....
@@paulosullivan3472 The nested squares in the solution require the outer fence to be a perfect square as well. In the slide before the solution the fence is a rectangle, not a square. That's my whole point...
@@fulla1 The description of the problem states, there are nine horses inside a square fence. The initial fence is square.
Good one
In the second puzzle we can also find by subtracting 178 from 200 which is equal to 22 so the second part of the sheet will be 22 more than 200 which gives us the numbers as 177 &178 and 223&224. We used 200 here because it comes exactly b/w them
Subtracting 177 from 400 will also result to 223; just sharing.
Which one of 223 and 224 is "22 more than 200", do you think?
@@Karsten3 i think he meant 22 more than 221
Umm no, because that would be 222 not 223.

Everyone thinks they are 1st until they refresh 😹😹😹
Happy 2023 :) Your puzzles are very good, however (in regards to the one in the thumbnail) it would have been better if you generalized; it does ruin the diversion (sizable horses), but it'd be more useful to establish how many x-vertice with particular symmetry polygons you'd need to isolate y objects which can exist anywhere in their isolated area.

I solved the 2 nd question using AP.
DATAPARAMOUNT
3rd question was from KVPY( Exam in India )😁😁 all question was too good and tricky 🤩👍
Ok for the last one I just poured half of the 7 barrels into the 7 empty barrels so there were 21 half full barrels. Also works, right?
Nope, you don't have measuring apparatus so you won't be able to halve them properly.
The only measurable transfers are when you empty a barrel, or/and fill a barrel. Of these, any transfer from a full barrel just switches the barrels; any from an empty barrel does nothing. Half into full does nothing; half into empty switches.
Only half into half changes it: from h+h to e+f. Doing this twice gives 9 full, 9 empty and 3 half-barrels, which can be divided in 3 sets.
Is the code DATA PARAMOUNT
At #4, I thought the clock does not work whatsoever no matter what you do. I didn't know you could adjust it. I made the problem harder than it should, but still found the solution.
1 I failed and will probably not remember the answer.
2-3 I got.
4 I didn't get, the Network Time Protocol uses the exact same logic (nice). Somehow I didn't remember it (thus I can't really reinvent NTP)
5: I got the start, but not the full problem. I did get that 3.5 barrels needed to go to each son, but _not_ how to equally distribute everything.
In the absentminded philosopher problem... he leaves to walk to his friend's house exactly at sunrise. When he gets there, he uses his friend's internet to check the what time sunrise was that morning, the time of arrival, and the distance between their homes. Using these facts, he's able to calculate his walking speed. Checking the time before he sets out for home the next morning, he knows how long it will take to walk home and therefore what time it will be when he gets there.
Great idea. Even simpler: He uses his friend's internet to check the what time sunrise will be next morning at his home. So he just need to be awake at home at sunrise to set the time.
Barrel riddle
Let's simplify riddle to 2-D world. You can angle the barrel so it's top right and bottom left angle will be at the same height. And excactly half will be still in barrel.
_Stop, but there is no instruments..._
Woooooowwwwww
For the Barrels i got a different solution - to be evenly distributed the number of a certain barrel type needs do be divisble by 3. That could mean 0,3,6,9,12
I pour half of full barrel in an empty barrel (so i have one full barrel less, and en empty barrel less but two half barrels more) 6 full 9 half full 6 empty so each get 2 full, 3 half full and 2 empty
You do not have a measuring scale.So, you cannot measure whether you have divided it into 2 equal halves.
1ST riddles has one more solution, the first square draw over any horse and second sqaure draw over the first square .
#3 the solution whilst correct is overly complicated. Let's take X as the amount of evaporated water. Then we have a simple equation 99-X=0.98(100-X) => X=50
The plot of n/n-1 throws a lot of people off. The difference between 0.99 and 0.98 is not a matter of 1 kg of water lost which is what many would intuitively guess, but a matter of 50 kg of water lost. 99% weight by water to start is 99/(99+1), but 98% weight by water is 49/(49+1), so you've gone from 99kg down to 49kg. Bizarre twist!
Better answer for #1: only ONE square fence needs to be added, not two, to be able to isolate 9 horses: the first diagonally placed fence shown at 1:08 in the video, but slightly larger, so that its four corners are outside the original fence, forming four isolation areas outside it. That keeps the same four isolation corners of the original fence, and forms a large center isolation area. Fence construction is not done when horses are loose. As each area is finished being built, put one horse in it.
👍 Well done! Outside the box solution!

#4: Philosopher notes the time on his own clock without winding it. Philosopher notes time he arrives at friends house. Philosopher leaves friends house at the same time as his own clock had read. Philosophers gets home and winds and sets and his clock to what his friends had read when he had arrived.
This is incorrect. Let's say, P started from 10 am from his house and reached his friend's home where he finds the time to be 10 30am. P doesn't know how the clock at his home is, slow or fast with this information.
Now he starts at 10pm from his friend's home. He finds the time at his place to be 10 40pm upon reaching. Do you think it is right to set to 10 30pm in his clock? We still don't know if the clock is slow or fast by doing this. What is right is that, we know the time and distance shall be equal from his place to his friend's, since his pace is contant. If we consider 30 minutes from his place to his friend's and find 40 mins from his friend's place to his, then the total time is 70 mins, dividing by two will give the actual time taken, 35 mins. That means, he has to set the clock to 10 35 at his place. If he finds it 10 20 pm at his place when he reached, then it is 30+20=50/2= 25, that means he has to set 10 25 in his clock. This way, P gets to know if he had a slow or fast clock and also sets the right time. It's pretty much the same method as mentioned here.
Not sure if Jaham's explanation is correct (or unclear) but to check your plan:
Let's say his clock says 0700 when he leaves. The actual time is 10:30. He arrives at 11:45 (1:15 travel time). he stays for the night and leaves at 0700 (arrives at 08:15), then sets the clock to 11:45. Obviously, incorrect solution.
You can work with it if you do wind it up and halve the difference upon return - that'd get you 08:15. Returning at the set time is not necessary though: it's just the same principle.
Probably easiest though is just to wind&set the clock to 00:00, walk over, observe the time (say 14:45) and walk straight back. Say the clock then says 04:28, he'll know his travel time (04:28/2=02:14) and can add it to the observed time.
For the forth desert puzzle I have *another solution*
He can see the altitude of sun and begin his journey then when he reaches his friends house he checks the time there eg. 10 at night
The next day he would start returning at the same altitude of sun so as he would take the same amount of time to return, he could turn the clock at the same time he saw in his friends house eg 10 ,he just have to set it to am rather than pm
noone can measure the altitude of sun correctly without any proper measuring instrument

The oil one can also be done without shifting oil in any barrel. 2 sons will get 3 filled 1 half filled and 3 empty barrels totalling 7 barrel and 3.5 oil. The last son will get 1 empty one full and 5 half filled barrels. Deal done.
I solved all the problems.👍
Why transfer the oils from one barrel to other while it can be distributed equally ?
It was asked to share equally. So considering first number as full barrels, second number as half full barrels and third number as empty barrels. First son would get 3, 1, 3. Second son would get 3, 1, 3. Third son would get 1, 5, 1. With this approach, every son would get 3.5 barrels of oil and 7 barrels without the concept of transferring from one barrel to other.
In question it was mentioned As the number of full, hf,empty barrels should also be same. That's why I guess
Ask any parent with three kids.
#5...1 full,5 half,1 empty barell can also distributed
In No. 4 we do not know if the philosopher wound up the clock before going to his friend. It is only known that the philosopher forgot to wound up his watch and several times later he went to his friend.

You're right. It's wasn't clear in the problem.

How does the philosopher of the 4th riddle make sure it takes home the same time for both ways? He would need another walk to his friends house to make sure he’s right about that…

This is not a solution, read again what is required to be given to each son, it's not just the same amount of oil and same amount of barrels, but also the same amount of full, half full and empty barrels - 3, 1 & 3 respectively is the only solution

#4 was crude, the solution shown seems random, because it added elements which were not discussed at the beginning.
#5
You can also transfer 1 full barrel into 2 half barrel, resulting in:
1 full to 2 half = 2 full + 1 empty
do that 2 times and you have your answer.
Yeah that's how I did it. It's effectively the same solution.
same but how you will measure exact half?
@@radium990 When you try to empty the full bottle into the half bottle, you're gonna be able to empty ONLY half of it. Since all the bottles are the same size.
Riddle 5 best solution
First we will give 2full ,2half full and 2 empty barrel to each son
So total 6full 6 half full and 6 empty barrel will be given in total
Then we have remaining 1full 1half full and 1 empty barrel so
We will pour half of full barrel to the empty one and we will end up by having 3 half full barrel we will distribute them equally
So each son will get
2 full ,3half full and 2 empty barrel
Easy solution to the Q5 oil barrel problem - Empty half of the full barrels into the empty barrels and that it! Each son gets 0 Full barrels, 7 half full barrels and 0 empty barrels :)
There's no measuring device.....how will you know that you emptying exactly half of the full barrels
In the oil problem, you have a contradiction. You say you have no measuring devices, and you also say you have barrels. Barrels are measuring devices. You go on to assert that you can't pour half the oil from a full barrel to an empty barrel because you have no measuring devices... why couldn't you simply pour until the level of the oil is the same in both barrels?
You have to assume "no measuring device" means it's impossible to determine any volume except "full" and "empty". It's just a rule given to you in a logic puzzle. Certainly there are ways to work around it but that's not solving the same puzzle anymore.
@@letao12 Even if one accepts that particularly arbitrary rule, the barrels are still measuring devices. The whole point of the problem is to use them to ensure each brother gets an equal measure of oil.
@@applejuicefool69 As I said, "no measuring device" means no way to find specific volumes other than "full" and "empty". You're trying to read the rule hyper-literally and missing the point of the puzzle.
@@letao12 Not reading it wrong, just saying he could have phrased it better.
These were all too easy. I wish we would get more than 10 seconds to solve them - but I did manage to solve all in 10 sec, each. The clock (#4) explanation you gave was too long. I would go to my friends house and look up when sun-rise was to happen the next day and go back home and wait for the sun to rise the next day and then correct the clock to the correct time. BTW I have an IQ of 157 so this is too easy for me, but I can see why you guys are struggling. The last one (the oil barrels) was especially easy and I solved it straight before 5seconds had passed.
Puzzle 4: if he sees the correct current time at friends home, can he not wind up his watch to the same time?

Sucked in
As the philosopher is absentminded, he forgot that his clock wasn't a wind-up, but an electronic one. So, by returning home, the clock kept showing the correct time.
The riddle, in the way stated above, doens't exclude this possibility.
The first question the fence was a rectangle at first

For 5th puzzle, another answer: each son has 2 full, 3 half-full, and 2 empty barrels
👍
Oh, but wait a minute...
It means that you will have to split 1 full barrel in 2 halfs. Yes, you have 1 empty barrel, but as the problem sais: "you don't have any measuring device". 😕
But, wait a minute...
You don't really need a measuring device to split in half, right? You transfer untill you get the same level in both barrels.
And BTW, your solution requires less work than the solution proposed in the video. 👍 😎
The absentminded philosopher is that friend who asks you for a dollar every time he sees you, isn't he? His friend replies, "What time is it? Time for you to buy a watch!"
Fun puzzles, I wanted to debate semantics for a couple but it was nice to challenge my brain a little at the end of this YT rabbit hole. Thanks!
your oil redistribution of 2 half oil barrel making 2 full barrel is interested, but the father doesn't have to do so much work to distribute equal oil and barrels. Only ONE HALF FULL should do the deal.
One will have another way but still same number of barrels and volume of oil.
I need to check the video again. But since 2 half barrels make one full and one empty that appears in every distribution. The old man can spare his strength. I must have forgotten one part of your exercise question.
