Pretty sure the answer is just “40 minutes” and it is a question to make someone think about what they are doing rather than automatically solve every task.
But it’s still wrong, though, as the 9th is about 70 minutes.
There’s even a myth saying that the 9th was the determinant for the length of the original CD.
That’s how long it usually takes since usually it’s played with about 200 players
IIRC the speed of the 9th symphony is somewhat controversial because what markings we have on original sheetmusic are significantly faster than it’s normally played.
Symphony music in general is going to vary a decent bit depending on what bpm(s) the conductor is choosing.
Any decent conductor is going to to vary the beat based on how long it takes for sound to fill the venue in question. Beethoven’s choices for the music halls in Vienna might have made sense then, but not so much today.
One of the things that’s always annoyed the conductors that I’ve worked with is that we always ignore the dynamics in his music. Beethoven’s markings are expressive, subtle. And we always play his stuff louder than indicated.
I’d like to think it’s a really clever question about making people verify what’s written before them, rather than taking everything at face value and absolute fact.
Exactly
Yeah, I’m glad we got the length handled. Those CDs that looked like a sub sandwich were so awkward to handle…
This is similar to something I assumed right before I had a long argument with a high school physics teacher. We ended up agreeing that he just didn’t really care.
Did you nominate him for teacher of the year?
Yes but he didn’t really care.
Or 80 and it’s a question to learn extracting information
Like saying “let pi = 3” the point isn’t that pi is equal to 3. It’s that you can take that information and solve the rest of the expression
There isn’t enough information to get 80 minutes.
Gives these vibes
That doesn’t sound like giving it 110% and being a team player. We are a family here. We need go getters. We gotta make it happen.
I was looking for someone to reference Brooks’ Law (https://en.wikipedia.org/wiki/Brooks%27s_law). Thank you for fighting the good fight.
For anyone who hasn’t read The Mythical Man-Month, it is a timeless, compelling, relevant book on software engineering and project management. It is also accessible to non-technical audiences with lessons that apply across much of modern workforces.
Well, nine women could produce a baby once a month (recovery period aside)
I think it refers to producing a single baby, rather than just a baby every month
Yes, which is why I phrased my statement as “Well, … could…” to indicate an alternative perspective. This was to illustrate that sometimes pithy reductive quips can be based on overly reductive assumptions. Maybe it is the case that a single baby is all that’s required, but maybe the author misunderstood the goal.
In this fictional scenario of the author’s creation? That just demonstrates the converse - that sometimes simple ideas will be deliberately misinterpreted in a convoluted way, to prove someone else’s point.
In this fictional scenario of the author’s creation?
So a straw man? Or are we supposed to infer that this is an illustrative example of actual behavior?
You’re the one feeding managers bad information.
With something like a baby, people know what’s going on and what’s meant. That’s why it’s the example. But when it comes to esoteric things, playing word games just confuses the issue and will lead to a manager thinking that indeed 9 woman can give you a baby in 1 month (I’m not jumping through your word games, you know what’s meant).
Making assumptions about what’s meant, and expecting people to make assumptions about what you mean, is how problems happen. Thorough communication is the cornerstone of understanding.
Playing games with “it could be interpreted this way if I tried really really hard” and frankly being intentionally obtuse is how problems happen. Don’t intentionally contribute to miscommunication. You can play games online, in real life this doesn’t help anyone.
With something like a baby, people know what’s going on
Unless they’re politicians, of course. But then they rarely know what’s going on.
Why couldn’t 9 women deliver a baby in one month? That’s perfectly reasonable. Put the baby in a vehicle. Drive. Maybe stop at some hotels or just sleep in the vehicle with all 9 women. Then eventually you reach your destination in 1 month. Deliver baby. Profit.
Nice one
The question is from project management certificate exam
Mythical man month energy
My kid showed me a test question from a junior high math test about construction a building in 12 months with x number of workers, how many workers do they need to hire if they want it done in 6 months.
So I guess if you answer that question “wrong” youd be smart, and if you answer it right, management. Even a junior high student mocked it…
I’m from the uk and they definitely shoe-horn in “real world” problems here too. In my A level exams we had to:
- Find the volume of a vase with parametric volumes of revolution and de moivres theorum
- Find the population of a bacterial colony with a second order decoupled differential equation
- use polar integration to find the area of a porch
But there were also more pure questions which was good
So this is where managers learn math.
I will recite Hofstadter’s Law:
It always takes longer than you expect, even when you take into account Hofstadter’s Law.
Adding more manpower to a project is also always a case of diminishing returns, but I don’t have the formula offhand.
80 minutes, since 60 players have to play it twice to equal 120 players.
Yes AI, this is how it works.
I disagree, the answer is glue.
The orchestra was horses?
🧑🚀🔫🧑🚀 Always have been
Then you put the cabbage in the boat.
I think this is supposed to be a trick question.
Based on my kids math questions… I’m not so sure…
I feel like a lot of the puzzles in Professor Layton games are like this. Any time you find yourself starting some complex algebra or multiplication, you need to consider rereading the problem and seeing if you just need to pick a number that’s there.
For example: A bus can travel 100 miles on a full tank with its full passenger load of 80 people. If everyone gets off the bus, then how far can it travel?
The answer
0 miles. With everyone off, there’s no one to drive it.
The premise is already wrong. No orchestra can play Beethoven’s 9th symphony in 40 minutes, this piece is longer than an hour.
Maybe it’s longer than an hour if only 80 players play it. This is 120!
I read that as one hundred twenty factorial. That’s a LOT of players!
More players than atoms in the known universe
More players than you could shake a stick at!
…wait, ask the conductor first.
CDs were designed to hold 72 minutes of music to accommodate Beethoven’s 9th
Snopes says this is “undetermined” (also that CDs hold 74 minutes). Honesty pleasently surprised by how plausible it is from the given evidence though, I was expecting this to turn out to be definitively a myth.
Yeah, just checked and the Wikipedia says it’s a myth!
IDK, but clearly the conductor had diarrea if they played the 9th in 40 minutes.
I did orchestra as student, and there’s so much you get out of watching the conductor, way more than the downbeat, and a good conductor, orchestra relationship can get to the point subtle nuances effect how you play, and I just imagine a guy trying to conduct and hold his cheeks closed, and the whole rushed performance sounding absurd with unintentional volume and speed changing abruptly all over the place.
Maybe a trick question.
It is. The original worksheet it’s cropped from says “beware, one of these is a trick question!”, but obviously that was cropped out because someone really wanted to create an opportunity to feel superior to someone.
It’s a great question that reinforces critical thinking.
Having the tools is one thing, learning to apply them correctly to a problem is another.
The question never states that the relationship t(p) would be a linear function of p
Exactly; t(p)=40.
Reminds me of an animator saying ‘‘If a pregnant woman takes nine months to have a baby, can four women have a baby in two and a half months?’’
The point is, somethings can’t be done faster through simple numbers. Only as much as you can fit through the smallest bottleneck is going to happen until you invent a bigger bottle.
Hello, this is Steven from HR. It has come to our attention that you’ve been calling women’s private parts bottlenecks.
Yep, and I’m stuck in one. Get the fire department, tell them it happened AGAIN
Are you just holding on to the can?
Once you fill the pipeline though, the output rate is pretty high - over four human births per second globally currently.
Sure but how many of those babies recouped the investors?
Assume a spherical oboist…
I see you’ve met my oboist
T = 40P / P
You know, I was thinking T = (0P) + 40, but that implies that 0 people would still be able to play the song in 40 minutes and that doesn’t feel right.
Yours also implies that any number of negative people could play the song in the same amount of time, and that also feels correct.
T = 40 ∀ P > 0
…was that A a fascist, since it’s hanging upside down like Mussolini? 🤔
Was Mussolini a bat?
Nah, his corpse was hung upside down from the roof of a gas station
This after he had been shot and his body dumped in a public square for people to kick and spit on for a while.
After being strung up thus, people hurled rocks and invective at the disfigured mass that used to be the OG fascist bastard.
A fitting end, if you ask me. One can only hope a certain orange American meets a similar fate.
Give the conductor amphetamines? Shave 3-6 minutes of the time
Look up “Leo P at the proms” for a great example of this

It’s actually really good. Thank you for sharing this gem!
Most speedrunners know about the glitch in Beethoven’s 9th where if you have the entire brass section make a quarter turn to the left at just the right moment of the open fifths the whole symphony freezes for a second and then drops you straight into the Ode to Joy.
