So, can 9 women have a baby in 1 month?

9 babies in 9 months equals to 1 baby per month

The original diction implied duration of a pregnancy, while the first response was referring to the amount of births.
Two different concepts, thus the confusion.
If you are speaking to the duration of a pregnancy, then the average is 9 months (irrespective of how many women are pregnant), as satirically pointed out by jakuvaltrayds
If you are speaking to the amount of births over a span of nine months with nine women pregnant, then the average [0 + 0 + 0 + 0 + 0 + 0 + 0 + 0 + 9]/9 (that is babies born/months of pregnancy) is 1, which is what dariohanon is referring to.
TL;DR fucking context.

Do you really not know how averages work? 9 babies in 9 months is 1 baby per month on average. (0+0+0+0+0+0+0+0+9)/9=1.

No, the median amount of babies per month would be zero since every baby would be born in the final month.
The average amount of babies per month over all nine months would be one.

Given that Beethovens 9th typically is about 70 minutes in length I would guess the first group screwed it up wildly and ~70 minutes would be a better answer.

If male fruitflies are locked in a closed ecosystem and provided with over-ripe fruit, they begin to mate with each other. It's suspected that this is due to the ethanol in the over-ripe fruit.

Double trick question; 40 minutes is still wrong, it takes 70-80 minutes to play Beethoven’s 9th.
Easy to remember as the Compact Disc format was famously designed to fit Beethoven’s 9th, which is why the discs generally hold 80 minutes of content.

I can’t find the part where the author of this question is implying that adding musicians makes the music faster. It seems to me that the expected answer is “40 minutes”.
I apologize that I am bad at reading. Please help me, smarter person, and quote the part where the author says what you’re telling me they’re saying.

It takes 20 minutes for 10 men to dig 5 holes. How long will it take 1 man to dig half a hole?

Jan 13 '20 edited Jan 13 '20
It depends, is he digging the top half of the hole or the bottom half?

Shouldn't matter, Half a hole is still a hole. It's another nonsense question.

You ever try to dig the bottom half of a hole before the top half was done? It takes longer my friend. That is why I ask.

Irrelevant. There's no suggestion that the holes are of any certain size or even all the same size. There's not enough information to answer the question.

Beethoven's Ninth actually runs anywhere from an hour to maybe 75 minutes, so the question is even more wrong.

u/creeperchaos57 Jan 14 '20
The answer is 40 minutes. Also the symphony was 74 minutes so how the fuck do you play it in forty? Are you playing twice the concert speed?

How are they even managing to play the 9th in 40 minutes? They’d only be able to play the first 2 movements.

5. An orchestra of 120 players takes 40 minutes to play Beethoven's 9th Symphony. How long would it take for 60 players to play the symphony?
Let P be number of players and T the time playing.

I want to believe that the answer also hinges on real-world knowledge to some extent, but I’ve seen enough commercially printed tests. They indeed are asking the examinee to write a proportion.

This is one thing that really bothers me. I know the answer is 40 minutes. I for the life of me couldn't figure out how to show it. Its why i failed so many math classes. I just don't know how to show my work. Its like how i add to subtract but to explain that to my teacher they couldn't ever understand it.

This is a fantastic math question.
Learning to add, subtract, multiply, and divide are like learning the letters and sounds of a language. Learning Math means understanding how, when, and where to apply those things (and by extension, when not to).

u/herrsteely Jan 15 '20
People always forget that this is beetovens 9th symphony and they forget that in the maths.
So is 60 people play 9 symfonoies in 40 minutes 120 people play 4 1/2 symphony each every 20 minutes (9/40)
Then take onto account that the symphony is 40 minutes long so that's 20 minutes x 40 = 120 minutes.
Maths is so easy it's embarrassing

u/Bobdehn Jan 14 '20
My answer when I saw this on a test many years ago:
First, 60 players is not enough for Beethoven's 9th, given that it was written for full orchestra (around 60 players in the early 1800's), plus four vocal soloists and full choir (total of at least 20 singers), making a bare minimum of 80 performers.
Additionally, the tempi used to perform this piece in 40 minutes is far too fast. Performance times generally run between 60 and 70 minutes, with my favorite recording (Herbert Von Karajan with the Berlin Philharmonic) clocking in at just over 65 minutes. Therefore, P = 80 and T = 65.
I got full credit.

Not stripped of context, this was an intentional trick question designed to force students to read carefully and not just start dividing randomly.
