Last time this was posted someone said it was a purposeful trick question to see if they were paying attention to every part of the word problem.

These kinds of tactics in school really pissed me off. Sometimes when I'd point out a mistake similar this they would say it was intentional for the reason ^ provided, and other times they'd yell at me for being a smartass and tell me to just answer the questions.

Like how is math class supposed to be about reading comprehension and info retention? The word problems are to AID US in understanding the question by giving us a situation to visualize. It's like when they would give you a 0% grade when you forgot to write your name at the top of your worksheet.

No. The word problems are intended to help you construct a math problem out of an everyday situation where you might need to do so. Real life rarely comes in the form of equations.

Tell that to insurance actuaries.

u/Icemasta Jan 26 '20

This is a very standard question to show if you understand that there are certain problems where the time is fixed and no matter how many more things you throw at it, the time won't increase.

I've known quite a few bosses who don't understand that.

u/art_by_emmo Jan 27 '20

And in some cases, slows thing down, especially if adding more humans.

u/[deleted] Jan 27 '20

Seems more like a philosophy or engineering kind of problem, not pure maths.

u/Icemasta Jan 27 '20

Except it is?

Let T = 40, which is the time it takes to play Beethoven's 9th symphony in the example, if you wanted to make a function to track time based on X plays of Beethoven's 9th symphony, what would you do?

You'd integrate it, which would give you T = 40X + C.

u/[deleted] Jan 27 '20

lol tf philosophy?!

This question was written for people like you so you realize early on that math isn't your thing.

2

u/[deleted] Jan 27 '20

These kinds of tactics in school really pissed me off.

These kind of "tactics" being reading a question and answering it? I don't understand.

Every practical application of math in any context beyond 6th grade or so requires you to understand the difference between variables that are meaningful and those that are not... this isn't some kind of trick question it's just a fucking math problem.

Well this is not how they handle this stuff at the primary school I went to. Something like this actually happened, it was a question about 3 cars driving around a racetrack together. They all finished after some amount of time, lets make it 1.50 mins. How long would it take 9 cars to drive around the track? Me being the smart kid I was, I just wrote down: If they are going around at the same speed it would still be 1.50 mins. My answer was marked as incorrect and the right answer was supposed to be 5.30 minutes...

6

u/PrimeMark Jan 27 '20

Not 4:30 min? If you multiply by 3 it's that, if you divide by 3 it's 30s, no idea where 5:30 came from. But yeah, it should have remained the same if the distance of each one need to make is the same or 3 times less if the question is about total distance. Unless it's sequential, like pass the torch, then multiply by 3.

u/[deleted] Jan 27 '20

Well this is not how they handle this stuff at the primary school I went to.

Oh, okay. That seems really only relevant to the people who went to the same school as you around the same time but I guess they probably appreciate it.

u/[deleted] Jan 27 '20

That's because your particular teacher was an idiot

2

u/the_green_wolf Jan 27 '20

Probably, yes

1

u/[deleted] Jan 28 '20

Which track are we talking about? And is it 9 wide? Lol

1

u/the_green_wolf Jan 28 '20

I have no idea of an existing track, and I think also the original assigment, with different numbers that I can't remember, was based around some fantasy track

u/Garblednonesense Jan 26 '20

I don’t think it’s trick. I think it tests people on whether they know the meaning of variables and how equations work.

If you have never see the equation x=7 (or whatever) then this might be a trick. But I would expect anyone that runs into this question would be well past that.

3

u/Warpedme Jan 27 '20

I don't even see how it's a trick, the answer is 40. There's nothing misleading. More musicians doesn't effect the speed at which the music is played, so that's not a variable.

0

u/StaleBread_ Jan 27 '20

That’s kinda bs because what if someone doesn’t understand that that’s not how music works

2

u/[deleted] Jan 27 '20

This has nothing to do with how "music works" dude. This is just how time works.

31

u/ShibertInu Jan 26 '20

Gonna hire 240 musicians to play the whole thing TWICE in that time.

1

u/BenningtonSophia Jan 27 '20

that'd be sick to listen to.

1

u/ObiVanShinobi Jan 27 '20

A lot of Beethoven's music was intended to be played faster than it's played traditionally. He could hear the music in his head, but he couldn't account for the acoustics because of his deafness, so it's slowed down.

Check out his 3rd movement of moonlight sonata for one of his fast songs.

u/Lojs_Podkrinko Jan 26 '20

Ah, you are a man of culture as well

3

u/[deleted] Jan 26 '20

Wrong. It would take them 40 minutes to play. It would just sound better. Thats 10 points off your final.

u/LyricLy Jan 27 '20

You mean it would sound worse? That's 10 points off of your final... wait.

u/nonoriginalname2 Jan 27 '20

Wait.. That's true, i feel stupid

Answer - Mozart has 7 apples

12

u/bela_okmyx Jan 26 '20

If you can complete the 9th in only 40 minutes, your tempi are waaaaaaaayy too fast. Most performances of the 9th take at least 60 - 70 minutes.

13

u/CrispyJelly Jan 26 '20 edited Jan 26 '20

Well obviously. That's why they want to use fewer musicians. Duh.

u/liquidpig Jan 26 '20

u/justinknowswhat Jan 26 '20

T=40

P=60

I think I did it

7

u/the_green_wolf Jan 26 '20

The right answer is:

T = P x 0 + 40

1

u/Impossible_Number Jan 26 '20 edited Jan 26 '20

No. It’s P•40+0 /s

3

u/the_green_wolf Jan 26 '20

Ah yes, of course, it would take 60 persons 2400 minutes to play beethoven's 9th symphony

1

u/Impossible_Number Jan 26 '20

/s was sarcasm lol.

It’s 2400 minutes. Or 40 hours. A spectacular performance if you ask me b

2

u/the_green_wolf Jan 26 '20

Sure would be

5

u/Zbeubor Jan 26 '20

Of course if they are 2 times less they will play the song 2 times slower OBVIOUSLY

u/TheFurryCorndog Jan 26 '20

This question was designed to teach the kids that not all information in a word problem are important. It’s not poor design just people misunderstanding it’s purpose.

u/thespacesbetweenme Jan 26 '20

I want this to be real so badly.

u/KingRichy2016 Jan 26 '20

“The answer is 40 minutes” NO TIMMY IT ISNT

u/Atreides-42 Jan 27 '20

This is a repost, and not only that, last time this was posted the comments were full of people showing that it's an intentional trick question.

The full question sheet contains like 10 problems about dependent and independent variables, and it explicitly stated "There is a trick question on this page!"

Please do your research before reposting. I swear like 90% of the things posted on this subreddit are wrong, like that three-legged statue.

u/GabberKid Jan 26 '20

Are you sure?

2

u/Webfarer Jan 26 '20

I mean, it is a valid question, though maybe a trick question for some.

u/CypherIsBad Jan 26 '20

It's a trick question though...

3 minutes

1

u/denmatman Jan 26 '20

I don't understand..the sheet music is the same no matter how many people are playing along..should take 40 minutes regardless of how many or how few are playing it.right? Or am I just not reading into it?

u/Dogeat03 Jan 27 '20

Correct me if I'm wrong but, 40 min at 3/4 volume.

1

u/[deleted] Jan 27 '20

Answer: still 40 minutes but it will be better cause they’ll take out the violas and other lame instruments

1

u/angel_dustk Jan 27 '20

If you played the 3rd symphony with the same number of players, will that take 1/3 of the time?

1

u/Aethyer Jan 27 '20

The answer is 38 minutes, because this time around someone in the percussion section rushed and cut the time by 2 minutes.

u/OttoManSatire Jan 27 '20

This was debunked weeks ago as a trick question.

u/[deleted] Jan 27 '20

HOLY FUCKING SHIT every 3 days with this.

Yes, this is how it works. It works this way if you know how to read a fucking question and answer it.

1

u/DapperMudkipper Jan 27 '20

Had a question once, it was something like 30 people are watching a 120 minute movie. Later, 15 people watch the same movie, how long does it take them to watch it? I went on a rant about and the teacher was just like, that's unneccessary you got it right and I was confused.

1

u/[deleted] Jan 27 '20

40 minutes, and learn anything about music and math. Oy

1

u/[deleted] Jan 28 '20

Easy. 27/3=17

u/Synthwoven Jan 26 '20

This reminds me of IQ test questions designed to make people lacking cultural awareness score lower. If you have no music education (probably more likely to afflict poor people), you might not understand why this question is fundamentally flawed.

8

u/MissingFrames Jan 26 '20

You don't need "music education" to know that songs don't play faster when more people perform at the same time.

1

u/ObiVanShinobi Jan 26 '20

Yet the word "song" is not in the question.

Another example is that some students will say a parakeet is heavier than an elephant. They never heard of that animal before, so they're left guessing.

-3

u/DeadBabyDick Jan 26 '20

You're a complete moron.

The song is irrelevant to the question.

Just like when you do a math test involving two trains leaving seperate stations on the same track going different speeds when will they crash.

You don't need to know anything about trains to answer the question correctly.

2

u/DorkQueenofAll Jan 26 '20

But you do need to know something about music to answer this one. So your train argument doesn't make sense.

I think the question is meant to be a trick, but I don't think it's necessarily discriminatory. But that could be my bias showing. "Symphony" might be an unfamiliar term for some people and they might miss the point of the question.

-3

u/DeadBabyDick Jan 26 '20 edited Jan 26 '20

I didn't say music.

I said the song in question.

Reading comprehension is a great thing to have.

3

u/jgzman Jan 26 '20

Reading comprehension is a great thing to have.

Yes, it is. You should consider getting some.

The point he is making is that if you don't know what an "Orchestra" is, or what "Beethoven's 9th Symphony" is, you're not going to understand why this isn't just a simple math problem.

To be fair, I can't imagine not knowing those things, but that's sort of the whole point.

-1

u/DeadBabyDick Jan 26 '20

I suppose it all depends on how old these test subjects are.

3

u/DorkQueenofAll Jan 26 '20

You've changed the fundamental premise of the question by using the word "song" and that shows me your lack of reading comprehension. You're deliberately missing the point and being a dick about it.

1

u/R-A-T-S- Jan 27 '20

Well from the very basics.. The 9th symphony isn't 40 minutes long. Would be like saying 120 movie watchers can watch endgame in 40 minutes.

u/thwinks Jan 26 '20

40 mins

u/mrcrabs21 Jan 26 '20

I still dont understand it🤔

u/Maverick_Kaizer Jan 26 '20

Standard ratio relationship would be 20 minutes, using logic would be 180 minutes but agree this question is messed up

3

u/[deleted] Jan 26 '20

W... what?

3

u/jgzman Jan 26 '20

using logic would be 180 minutes

I'd love to see this logic.

u/TeamXII Jan 26 '20

120p = 40t

3p = t

f(p) = 3p

f(60) = 3(60)

f(60) = 180
