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)
@@shambhav9534 You've still missed their point. Yes we know if 5 machines work for 5 minutes, they can make 5 doughnuts, you've just twice repeated what's said in the video... The question is do they all make 5 doughnuts each, meaning a machine makes 1 doughnut per minute. Or do they collectively make 5 doughnuts in 5 minutes, meaning a machine makes 1 doughnut per 5 minutes...

Confusion stems more from lack of clarity on if it's 5min to make 5 donuts PER MACHINE or 5 donuts TOTAL, which he neglects to clarify (though seemingly no one asks for this clarification either).
Because it's clear. "It takes 5 machines 5 minutes to make 5 donuts." It's total, not per machine. Otherwise it would be "it takes ... to make 5 donuts *each*".
5 machines (total), 5 donuts (total), 5 minutes (total). Obviously (or not), each machine is making one donut and it takes 5 minutes. 100 machines will take the same 5 minutes and you get 100 donuts.

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.
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. Obviously that's wildly overthinking the original point of the logic question but I also think if someone is asking a trick question it's valid to call them out for underspecifying the parameters of the question
@@Dybicus It takes five minutes per machine to make one doughnut. Increasing the number of machines has no effect whatsoever on the time it takes to make one provided all machines are identical.
There is no right answer. You could justify any answer you make because of the wording of the prompt: "5 machines, 5 minutes to make 5 doughnuts". You could read that legitimately as sequential booting of 5 machines that each have the capability of activating the next machine in line each taking 1 minute to make a doughnut. The lack of information in the prompt *necessarily* means you have to presuppose some information about the functioning of the machines (and of course as we all know from basic schooling, all presuppositions are inherently baseless).

As long the input and output are consistent, the rate won’t change. 1 to 1, pegged to 5 Though, the way he worded it, allows for many other factors to come into play, changing the answer.
The way it sounds to me is that collectively it takes 5 machines 5 minutes to make 5 donuts, in other words a minute per machine. So based on that understanding it would take 100 machines 1 minute to make 100 donuts.
i still dont understand why people dislike others pointing out parts of a video they like it's like being mad over someone quoting a line in a movie or show, or pointing out the action moves
Its pretty simple: 5 doughnuts, i n 5 min, from, 5 machines, means each machine took 5 minutes to make one doughnut. So 100 machines to produce 100 doughnuts would be five minutes, as that is the amount of time it takes for one machine to produce one unit.
it was never specified if each machine created its own 5 and, if so, if each machine was producing 1 donut per minute. Depending on those factors, the 100 machines could produce 100 donuts in one minute potentially.

The answer is 5 minutes. Took me a few seconds of understanding the question. I think most people rush to give the first answer possible instead of going over the question.
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.

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?

@@droundyCubbyCertainly wasn’t a teacher. Anytime a teacher asked a question like that, it was a multiplication problem. It’s actually the teachers and their use of questions in this format, that led to the wrong answers.
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.
that's the answer if you're dropping them in all at once...it takes 5 minutes to do everything necessary to make those 5 donuts with 5 donut makers. you ad another 5 donut makers to the line, it's going to take you more then 5 minutes...

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.
@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? As an overthinker, this is my exact thought process of the problem lol.
Regardless, to answer the question correctly, I believe that more information is required. One person operating all the machines, one person per machine, are all the ingredients available at each machine. Just don't have all the information, so I believe any answer is questionable.
I did all the calculations thinking it was still 5 machines. I even rewatched it and missed that completely. I feel stupid because if I noticed that I would've known.
It is a math problem, I think. 5machines 5 min 5 Donuts So 1machine 5min 1 Donut What is the production rate for one machine? 1/5(donuts/minute) Now (1/5)(d/min) * Xmin =Yd - this is for one machine For 100 you multiply by 100. Now we know Y=100(donuts). Therefore: 100*(1/5 *X) = 100 20X=100 X=5(minutes)
@@KaiReel23 You're overthinking it. We already have the answer = 1 donut takes 5 minutes. So long as the number of donuts is equal to the number of machines (in other words, each machine only makes 1 donut) then the answer will always be 5 minutes.
That depends on access to resources and the logistics involved. Making 5 doughnuts might be easy when you have one bag of flour, but when you need to make a deal with a flour producer to ensure you can supply 100 machines with flour, that's gonna take a lot longer.
The speed of the operation is 5 minutes. That operation can be parallelized to multiply the output by the number of machines but the speed of each operation remains 5 minutes regardless of how many machines are completing the same operation in parallel.
It takes them 2 weeks including one full weekend. The planner only requested 20 donuts worth of flour, the facility didn't factor for the increased power draw and most of the machines can't run... Additionally the drivers are on strike. The first 3 batches of donuts all fail quality checks because the ramp up wasnt properly considered. 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. Lastly at the same time as producing more donuts the boss has decided that the output is now actually 20 cupcakes, 20 Victoria sponges, 60 pizzas and 10 high end hand bags.
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.
Man im acoustic but this comment thread specifically is a great example. I'm gonna have to show my wife next time she doesn't understand how specific she needs to make instructions for a task I'm unfamiliar with.
