@@Walid_Kharseh it was the right explanation tho😂a donut takes 5 minutes to make ,no matter how many donuts you want to make,if you have the same ratio if donuts and machines it will always take 5 mins.😊

Correct. So busy thinking of how they'll look that they look stupid. I phoned a radio quiz when I was a kid and fluffed the whole thing lol. Even though I knew the answers! Not sure if radios even exist any more😅
It's a funny one as well, but it is DIFFERENT from the question in the video. Here you produce 20times more donuts but with 20times more machines, so it takes the same time : 5 minutes. It's not exactly really the thing here that the machines work on a timer (as pregnant women do)
Answer is 20 mins. But the question the wrong. He should have asked, If "each" 5 machine takes 5 minutes to make 5 donuts. Then how many minutes it would take by "each" 100 machine to make 100 donuts. Answer. 5 mins
We could also look at it as 100/5 doughnuts = 20 times the workload; 100/5 robots = 20 times the capability, so it’s being scaled up in workload and capability evenly, so it will take the same amount of time.
Hmmm, maybe not, if it's 5 machines taking 5 minutes to make 5 donuts, there is a hidden assumption there that all the machines finish making donuts at the same time of 5 minutes, that means that each machine is cooking one donut each and they finish making their respective donuts at exactly 5 minutes, assuming the number of donuts cooking at the same time in 1 machine will change the amount of time to cook those donuts, e.g 2 donuts cooking in 1 machine may take longer than 5 minutes to finish both, then that means all the donuts have to be equally distributed among the machines. So I'm not sure if 100 donuts in any no of machines lesser than 100 can really be calculated because then atleast 1 machine will have to cook 2 donuts at once, for whose time is unknown how long the machine takes in that situation. If it's 100 donuts and 100 machines it's solvable because it's the same conditions as the 5 in 5, because the machines are doing the exact same thing in both situations. Maybe 100 donuts in 301 machines would also work to be 5 minutes because 100 donuts could maybe only be cooked at minimum 1 donut per machine, so the first hundred machines are occupied with 1 donut each and the rest 201 machines are left empty.
The old man was right, if 5 machines can make 5 donuts in 5 minutes, then each machine can make 1 donut in 5 minutes. Therefore, 100 machines can make 100 donuts in the same 5 minutes

It's parallel because machines run in parallel, you don't start a machine to make a donut in 1 minute, turn it off, start the next machine for 1 minute and turn it off. Then you only need 1 machine. For you to need 5 machines, they must run in parallel and produce a donut in t = 0 to 5min, like it would take 4.5 minutes to cook each donut.
It doesn't matter because if you need a 5-machine contraption in series to make 5 donuts in 5 mins, you have 20 times as many of these 5 machine series when you have 100 machines. With 20x the machines, you have 20x the throughput because you can assume you have 20x the 5 machine-unit in parallel. Otherwise the question is unanswerable as it would mean the 100 machines are different to the 5 machines and hence incomparable.
@@scottclowe 20x identical machines doesn't *necessarily* equal 20x throughput due to potential diminishing returns of production, e.g. if the factory space is too small to accommodate efficient loading of raw materials into all machines simultaneously.

The correct answer is 8 minutes 33 seconds. Let me explain why. Sorry to toot my own horn, but I need to for a sec. I once took an ACTUAL IQ test and was asked a very similar question to this. I scored in the 97th percentile on that test, so I'm confident in the correct answer. Here's the reasoning. You have to ignore all preconceptions of what a "machine" and a "donut" are. Don't imagine literal donuts or ovens when answering this question. donut" and "machine" only variables with a mathematical relationship. Therefore, if it takes 5 minutes for 5 machines to equal 5 donuts, then mathematically it takes 25 seconds for 100 machines to equal 5 donuts (20 x 5 machines is inversely 5 minutes / 20) 100 donuts is 20x the 5 donuts, which means it would take 20x the 25 seconds, which is 8 minutes 33 seconds. This is the real, mathematical answer the question. Again, I was asked this in an IQ test and got the official answer correct. It's not a "common sense" question, it's a mathematical question. IQ tests don't ask "common sense" questions. Making you think about donuts and machines is a trick and misdirection away from the mathematical nature of the question. If you answer 5 minutes in real IQ test, you would get the question wrong.
@@kellyhandshoe904 Nope. If one machine needs one minute per donut, in that case 5 machines would produce 25 donuts!

@@chundelithelegendofdinkan 5 machines uses 5 minutes to make 5 donuts. How do you know that doesnt mean that 1 machine uses 1 minute but you can only run one machine at a time?
@@LOLLYPOPPE If only one machine can be run at a time, then using 100 machine will result in 9900 minutes of machine idle time. Which will result in a huge hike in cost. No one with their right mind will do this. Either 5 machines are used in the process of making a single donut or each machine can make a whole donut in five minutes. 100 minute is never the right answer.
The answer is 5 minutes. The fact that it takes 5 machines 5 minutes to make 5 donuts means that it takes 5 minutes to make each donut. So that means that if 100 machines were making 1 donut each to have a total of 100 donuts, it would still take 5 minutes. That is unless I’ve misunderstood the question and the initial proposition is referring to 5 donuts PER machine. So I guess this falls down to how you interpret the question.
The question is incomplete! It depends on how many donuts can the machine accommodate at once. For EXAMPLE let's say if a machine can only bake 2 donuts at once the whole logic is screwed because now the machine becomes a factor. If the machines are limited to baking only 2 donuts each, then the number of machines becomes a factor in how long it takes to bake 100 donuts. Here's how it would work in this scenario: Each machine bakes 2 donuts in 5 minutes. We need to bake 100 donuts. Since each machine only makes 2 donuts at a time, we need to calculate how many batches we need to bake in each machine to get to 100 donuts. Divide the total number of donuts (100) by the number of donuts made per machine per batch (2): 100 donuts / 2 donuts/batch = 50 batches Now we know we need to run 50 batches in total. Since each batch takes 5 minutes, the total time required would be: 50 batches * 5 minutes/batch = 250 minutes Therefore, with this limitation of 2 donuts per machine, it would take 250 minutes to bake 100 donuts using 5 machines.
For anyone wondering, this is priming. Its a stressful situation, the question weirds you out and you expect it to be a trick, so youre more likely to follow recent patterns. 5-5-5 was a recent pattern, so 100-100-100 is easily available.

I think some people might have thought each machine made a donut every minute after eachother in sequence, I mean that isnt impossible cause there is missing information
My logic is basically just there is 20 times more machines so divide the time by 20 but then there is 20 times more doughnuts to be made so it would be multiplied by 20/20 which would be 1 so its 5 minutes.
5 minutes. The key fact to recognize is it takes 5 minutes for 1 machine to make 1 donut. So 100 machines will need 5 minutes to make 100 donuts. The amount of time to make a donut per machine never changes.
You're forgetting the time it takes to press the start button. If it is one second per machine then the actual production time from pressing the last button to the fifth doughnut being produced is only 4:55.

It's the fact that the tasks are occurring in parallel that makes it tricky. It's not even a math question, it's a logic question. While common sense would tell you the machines can operate concurrently, common sense is kind of thrown out the window when you talk about a donut machine that can only make a single donut.
The way it’s phrased makes it seem more complicated than it is. This is like those trick questions they slip into tests that are so blatantly obvious but really don’t account for intelligence if you get them right or wrong 😆
It’s impossible to answer, you aren’t given enough information. Are all the machines the same and doing the same job? Or do they all work together to get one job done? Is it a conveyor system where all donuts enter the machine at the same time and not one by one? You can assume, but that just makes an ass out of u (and me). You can never be sure without more info.

5 machines takes 5 min -> 5 🍩. Then the answer is 5 minutes. Assumptions made: 1. He doesn't implicitly mean that "each" of the 5 machines take 5 min to make 5 🍩. 2. Adding or removing a machine from the group of 5 does not influence the rate of 🍩 made (X groups of 5 machines put together will make X times as many doughnuts as a single group of 5 machines). Then each of 20 groups of 5 machines (100 machines total) can run and finish in 5 minutes if they run at the same time, each group making 5 🍩 (100 🍩 total). The way the guy asked the question allows for a little ambiguity, so some basic assumptions need to be made in order to provide a definite answer... but yeah, 5 minutes
But what if the assumptions we make are: - 5 machines take 5 minutes to make 5 donuts, we assume that 1 machine takes 5 minutes to make 1 donut. So the rate is 5 donuts/5mins given a constant number of machines - assume we only have a limited number of machines, like in a real scenario - therefore 100 donuts with 5 machines we still take 100 minutes? We don't have an infinite number of machines irl?
What my solution looked liked after I failed initially and then put some thought into it: 1. 5 machines make 5 donuts in 5 minutes. Assuming it takes all 5 machines to make one whole donut (each prints out a part of it), they will make 1 donut in 1 minute. 2. In 100 machines, there is 20 sets of 5 machines. This many will make 20 donuts in 1 minute. 3. By dividing 100 donuts by 20, we get 5, thus finding that it would take 100 machines 5 minutes to make 100 donuts. The question was really vaguely put. Does one machine take full five minutes to make a donut, or do all five machines make one detail of a donut? No wonder people are confused: with important information left out, it's hard to conceptualize the question.

The workforce who run the machines are burnt out from having to adapt to the increased work with a rapidly diminishing skill level for all the new employees.

@@Kyo_Oni I had thought this too actually, but it's 5 minutes. If each machine made 1 donut per minute then 5 machines would've made 25 donuts in 5 minutes. Then 100 machines would make 500 donuts. As someone who actually likes math and used to be extremely good at algebra(haven't used it much since school though) I hate word problems. For some reason reading/hearing words instead of equations just makes things super confusing. I can usually work them out alright if it's on a paper cuz I can scribble out the words and turn it into an equation. But spoken word problems just don't work for me very well.
It’s a trick questions because it can be attempted in two ways One method is to think that 5 machines make 5 donuts in 5 minutes means that each individual machine is making 5 donuts in 5 minutes, equivalent of 1 donut per minute. That means a hundred machines would make 100 donuts in 1 minute as each machine makes 1 each in that minute. Another way to think about it is that the 5 machines collectively make 5 donuts in 5 minutes, which would mean that each machine makes 1 donut each in those 5 minutes. A 100 machines would take 5 minutes to make a 100 donuts in this case as each of the machine makes 1 donut in the 5 min duration. PS: my brain hurts
As well as underthinking, ergo jumping to conclusion... "5-5-5" and now it's "100-100-X" oh it has to be 100… There are several of these second grade math exams where adults get the answer wrong because they don't focus enough, they just skip to the fastest solution
@@maryamb9838 bro you idiot , 5 machines working together, how it takes 1 mins ??? 5 machines takes 5 mins means if each machine makes 1 donut then it takes 5 mins to make it ... Try to understand.
Think it right dont overthink. I like that people always find excuses about not being able to do basic logical thinking. They cant accept they need to develop...
Well he’s not specifying whether the donut production is in series or if they’re all running in parallel. In series, you can say it takes each machine one minute to make a donut, and all together they make five donuts in five minutes. In parallel you can say it takes all five machines five minutes each to make one donut.
It is bad 🥲 I mean... I teach German, English, Japanese and history... so as one can see I'm a languages-kind of person... but I can still cover for my colleagues in maths up till 8th grade (students would normally be about 14/15 years old) Not even to talk about the fact that this one was just about logical thinking...

Answer is 20 mins.
But the question the wrong. He should have asked, If "each" 5 machine takes 5 minutes to make 5 donuts. Then how many minutes it would take by "each" 100 machine to make 100 donuts. Answer. 5 mins
Omg are Albert Einstein?!!
We could also look at it as 100/5 doughnuts = 20 times the workload; 100/5 robots = 20 times the capability, so it’s being scaled up in workload and capability evenly, so it will take the same amount of time.
Hmmm, maybe not, if it's 5 machines taking 5 minutes to make 5 donuts, there is a hidden assumption there that all the machines finish making donuts at the same time of 5 minutes, that means that each machine is cooking one donut each and they finish making their respective donuts at exactly 5 minutes, assuming the number of donuts cooking at the same time in 1 machine will change the amount of time to cook those donuts, e.g 2 donuts cooking in 1 machine may take longer than 5 minutes to finish both, then that means all the donuts have to be equally distributed among the machines.
So I'm not sure if 100 donuts in any no of machines lesser than 100 can really be calculated because then atleast 1 machine will have to cook 2 donuts at once, for whose time is unknown how long the machine takes in that situation.
If it's 100 donuts and 100 machines it's solvable because it's the same conditions as the 5 in 5, because the machines are doing the exact same thing in both situations.
Maybe 100 donuts in 301 machines would also work to be 5 minutes because 100 donuts could maybe only be cooked at minimum 1 donut per machine, so the first hundred machines are occupied with 1 donut each and the rest 201 machines are left empty.
The old man was right, if 5 machines can make 5 donuts in 5 minutes, then each machine can make 1 donut in 5 minutes. Therefore, 100 machines can make 100 donuts in the same 5 minutes

@@mohammadaliagharazi7518 You're adding unnecessary variables to a rather simple question.
Under the assumption that all of the machines run at the same time with each of them having the capability to make a singular donut at a time it means that it takes a machine 5 minutes to make a singular donut since 5 donuts have been processed by 5 machines.
The same logic applies to a 100 machines making a hundred donuts since a single donut can be made in 5 minutes so if we get 100 machines running at the same time we get 100 donuts in 5 minutes

For those who doesn't know.
This is indeed related to Aptitude- Time & Work concept
5x5/5=100xt2/100
so t2 (time 2) = 5 minutes
"Did those 5 machines produce 5 doughnuts in parallel or in serial?" is the appropriate response.
It's parallel because machines run in parallel, you don't start a machine to make a donut in 1 minute, turn it off, start the next machine for 1 minute and turn it off. Then you only need 1 machine.
For you to need 5 machines, they must run in parallel and produce a donut in t = 0 to 5min, like it would take 4.5 minutes to cook each donut.
It doesn't matter because if you need a 5-machine contraption in series to make 5 donuts in 5 mins, you have 20 times as many of these 5 machine series when you have 100 machines. With 20x the machines, you have 20x the throughput because you can assume you have 20x the 5 machine-unit in parallel. Otherwise the question is unanswerable as it would mean the 100 machines are different to the 5 machines and hence incomparable.

1 minute..... 5 machines 5 donuts 5 donuts.. that's 1 minute per donut. It would make 500 donuts in 5 minutes to use 100 machines
The correct answer is 8 minutes 33 seconds. Let me explain why. Sorry to toot my own horn, but I need to for a sec. I once took an ACTUAL IQ test and was asked a very similar question to this. I scored in the 97th percentile on that test, so I'm confident in the correct answer. Here's the reasoning. You have to ignore all preconceptions of what a "machine" and a "donut" are. Don't imagine literal donuts or ovens when answering this question. donut" and "machine" only variables with a mathematical relationship. Therefore, if it takes 5 minutes for 5 machines to equal 5 donuts, then mathematically it takes 25 seconds for 100 machines to equal 5 donuts (20 x 5 machines is inversely 5 minutes / 20) 100 donuts is 20x the 5 donuts, which means it would take 20x the 25 seconds, which is 8 minutes 33 seconds. This is the real, mathematical answer the question. Again, I was asked this in an IQ test and got the official answer correct. It's not a "common sense" question, it's a mathematical question. IQ tests don't ask "common sense" questions. Making you think about donuts and machines is a trick and misdirection away from the mathematical nature of the question. If you answer 5 minutes in real IQ test, you would get the question wrong.

Nope. If one machine needs one minute per donut, in that case 5 machines would produce 25 donuts!

The answer is 5 minutes. The fact that it takes 5 machines 5 minutes to make 5 donuts means that it takes 5 minutes to make each donut. So that means that if 100 machines were making 1 donut each to have a total of 100 donuts, it would still take 5 minutes.
That is unless I’ve misunderstood the question and the initial proposition is referring to 5 donuts PER machine. So I guess this falls down to how you interpret the question.
Exactly the question was left a bit vague on purpose
The question is incomplete!
It depends on how many donuts can the machine accommodate at once. For EXAMPLE let's say if a machine can only bake 2 donuts at once the whole logic is screwed because now the machine becomes a factor.
If the machines are limited to baking only 2 donuts each, then the number of machines becomes a factor in how long it takes to bake 100 donuts.
Here's how it would work in this scenario:
Each machine bakes 2 donuts in 5 minutes.
We need to bake 100 donuts.
Since each machine only makes 2 donuts at a time, we need to calculate how many batches we need to bake in each machine to get to 100 donuts.
Divide the total number of donuts (100) by the number of donuts made per machine per batch (2): 100 donuts / 2 donuts/batch = 50 batches
Now we know we need to run 50 batches in total. Since each batch takes 5 minutes, the total time required would be: 50 batches * 5 minutes/batch = 250 minutes
Therefore, with this limitation of 2 donuts per machine, it would take 250 minutes to bake 100 donuts using 5 machines.

Se temos uma máquina que produz um donut a cada 5 minutos, quantas iremos precisar para fazer 100?
Em uma fábrica, percebeu-se que as 5 máquinas disponíveis e funcionais, produzem em 5 minutos 5 donuts ao todo. Para um grande evento foram alugadas 100 máquinas - todas estão funcionando, com a mesma capacidade e taxa de produção percebida na fábrica, sendo que não é possível as máquinas trabalharem juntas para diminuir o tempo de um donut- Sendo assim, em quanto tempo teríamos 100 donuts pronto para consumo?
E ainda assim, a resposta do sr está equivocada. Talvez ele já conhecesse a charada. Foi capaz de emitir a resposta esperada pelo provocador, mas sua explicação é equivocada.

5 minutes. The key fact to recognize is it takes 5 minutes for 1 machine to make 1 donut. So 100 machines will need 5 minutes to make 100 donuts. The amount of time to make a donut per machine never changes.
Took me 0.5 seconds to get that
You're forgetting the time it takes to press the start button. If it is one second per machine then the actual production time from pressing the last button to the fifth doughnut being produced is only 4:55. But for 100 doughnuts it would take 1:40 to start them all plus 4:55 to make them so 6:35 to make 100 doughnuts

Not quite. The question is actually very clear, the issue lies in is assuming the increase in the amount of machines would change the amount of time it takes to produce. This is really a question of production, not time.
It would have been more clear, but even if it was NOT at the same time, the answer is still 5 minutes
@The-cyber-imbiber Would it still be five minutes, if each machine had to he started manually? How far does one have to walk from machine to machine, if at all? Will any of the machines break down?

Machines (plural)
Regardless, to answer the question correctly, I believe that more information is required.

I immediately thought 5 minutes but got worried I was when I saw how confused the people were
5 machines takes 5 min -> 5 🍩. Then the answer is 5 minutes.
Assumptions made:
1. He doesn't implicitly mean that "each" of the 5 machines take 5 min to make 5 🍩.
2. Adding or removing a machine from the group of 5 does not influence the rate of 🍩 made (X groups of 5 machines put together will make X times as many doughnuts as a single group of 5 machines).
Then each of 20 groups of 5 machines (100 machines total) can run and finish in 5 minutes if they run at the same time, each group making 5 🍩 (100 🍩 total).
The way the guy asked the question allows for a little ambiguity, so some basic assumptions need to be made in order to provide a definite answer... but yeah, 5 minutes
That's it!
But what if the assumptions we make are:
- 5 machines take 5 minutes to make 5 donuts, we assume that 1 machine takes 5 minutes to make 1 donut. So the rate is 5 donuts/5mins given a constant number of machines
- assume we only have a limited number of machines, like in a real scenario
- therefore 100 donuts with 5 machines we still take 100 minutes?
We don't have an infinite number of machines irl?
What my solution looked liked after I failed initially and then put some thought into it:
1. 5 machines make 5 donuts in 5 minutes. Assuming it takes all 5 machines to make one whole donut (each prints out a part of it), they will make 1 donut in 1 minute.
2. In 100 machines, there is 20 sets of 5 machines. This many will make 20 donuts in 1 minute.
3. By dividing 100 donuts by 20, we get 5, thus finding that it would take 100 machines 5 minutes to make 100 donuts.
The question was really vaguely put. Does one machine take full five minutes to make a donut, or do all five machines make one detail of a donut? No wonder people are confused: with important information left out, it's hard to conceptualize the question.
Does each machine make a donut end to end , or the doughnut passes thru 5 machines in 5 steps to be completed

It’s a trick questions because it can be attempted in two ways

Another way to think about it is that the 5 machines collectively make 5 donuts in 5 minutes, which would mean that each machine makes 1 donut each in those 5 minutes. A 100 machines would take 5 minutes to make a 100 donuts in this case as each of the machine makes 1 donut in the 5 min duration.
