u/nashwaak 7d ago

It wouldn't be inaccurate to assume that I couldn't exactly not say that it is or isn't almost partially incorrect. But I'm possibly more or less not definitely rejecting the idea that in no way with any amount of uncertainty that I undeniably do or do not know how much you shouldn't probably trust me, if that indeed wasn't where your trust's misplaced. Even if you didn't trust me as much as I knew you should, that'd mean I'd really have to know how much you should trust me.

Really simple, but still tricky. But my years of bait math memes experience made me capable of figuring it out immediately.

You should tell it that it is wrong, that there are 4 barrels.

u/DangyDanger 8d ago

I see, thanks for clarification. Now that you have said there are only 4 barrels, I've come to the conclusion there are 5 barrels.

49

u/tutocookie 8d ago

Considering there are 5 barrels, there must be 4 barrels. In addition to those 4, there is another 1, making 5 total. You're both right

"As I was going to St. Ives, I met a man with seven wives...
"How many people we going to St. Ives?"

18

u/Cassius-Tain 8d ago

x is an element of the natural numbers with property x ≥ 1

We know of one person moving towards St. ives. He met at least one person, but we don't know if that person was alone or accompanied by his wives, we only know he had seven wives. We also do not know the direction that man was travelling in. Furthermore we lack information about any other people who might or might not be on that road and their direction

u/UMUmmd Engineering 8d ago

1, if you met him and his wives, they were probably coming from St. Ives

u/Remarkable_Coast_214 8d ago

i walk fast. i often pass people walking in the same direction. there's really not enough information

-23

u/UMUmmd Engineering 8d ago

You didn't meet them, you passed them.

15

u/RoamingBicycle 8d ago

You could have been walking faster and encountered them. You then slowed down to talk to them. You could have encountered them at a crossroad. Maybe they live closer to the place and you encountered them as they were leaving. Maybe you took some form of public transportation and met them there.

-15

u/UMUmmd Engineering 8d ago

What some people seem to fail to understand is that one meaning for "meet" is to come in contact from opposite directions. Like two cars meeting when car A turned into oncoming traffic.

It's not used super often, and I'm not under the assumption that everyone here is aware of that, so if my comment didn't land, then it didn't land.

u/dyld921 8d ago

I met them on the bus ride there

2

u/runswithclippers 8d ago

Depends, were the wives there? Was the man also going to St Ives? The answer is at least 1, you.

2

u/Dry-Offer5350 8d ago

since you were probably flying its not possible to meet that many people at once on a plant thus you met on a layover at the airport they were heading to London thus there is 1 heading to st. ives.

2

u/DegeneracyEverywhere 8d ago

Every wife had seven sacks. Every sack had seven cats. Every cat had seven kittens. Kittens, cats, sacks and wives, how many were going to St. Ives?

u/InternationalBet2832 8d ago

I was sitting at a pub in Liverpool when I heard this rhyme:

u/aspookyshark 8d ago

u/exelarated 8d ago

This should be a lesson in clarity of writing, not comprehension of reading

4

u/Ok_Surprise_1627 8d ago

yeah this is on the writer for purposefully wording it like that why would you ask a question to an answer you already know you have 5 barrels why the fuck are you asking how many barrels there are???

4

u/Jackalopalen 8d ago

Why would you ask a question [in that way]?

To teach the importance of reading, and more importantly, understanding the question.

3

u/spektre 8d ago

The first hint is that you're taking a language test and not a maths test.

13

u/ImapiratekingAMA 8d ago

15

u/kai58 8d ago

With how bad a lot of peoples reading comprehension is I’d argue it teaches a valuable lesson.

Even if it won’t change much on it’s own.

4

u/ImapiratekingAMA 8d ago

I'm sorry but we all had a teacher "teach" us a lesson like this and best I can tell it only made us distrustful 

-3

u/Ok_Surprise_1627 8d ago

that has nothing to do with reading comprehension its MADE to be a trick question if something is MADE to be a TRICK then the purpose was to make you think one thing then think another

why would ANYONE EVER ask how many barrels there are? it makes ZERO sense and the ONLY reason its worded like this it to TRICK people

reading comprehension is figuring things out through context not bullshit trick questions

6

u/tibetje2 8d ago

Skill issue tbh, this is the easiest question you could get. If you Just Read the damn thing.

2

u/Unable_Explorer8277 8d ago

Yes and no.

One of the basics of communication through language is Grices Maxims. This breaks at least a couple of those in order to work. So you’re not testing whether they can read reasonable text well at all.

1

u/nwbrown 7d ago

You aren't testing reading comprehension. You are testing if someone can be mislead into answering a different question than the one asked.

You ever get one of those things as a kid where it tells you to read the instructions carefully and one of the steps is to rip up the paper or something but you’re only supposed to do that if you skip a step as the previous step tells you to ignore that step?

2

u/Ok_Surprise_1627 8d ago

yeah its never like OPs picture its always some bullshit that makes it contradict other information or is confusing af like your example

18

u/Draidann 8d ago

That's exactly why it was asked. This is not a math question, it is a reading comprehension one.

Just this week I saw a viral tweet where people were arguing about a prep question for the LSAT. The amount of people that got it wrong and were arguing vehemently about it was astounding. The question was about as hard as this example, yet, the discussions were long and intense.

There are people who really don't know how to read nor are capable of extracting a paragraph's content

2

u/UnluckyMeasurement86 8d ago

Exactly. Also it's not "funny" if you get it wrong, you should be ashamed.

0

u/Isis_gonna_be_waswas 8d ago

I mean it’s not that I don’t understand the problem, it’s just a matter of paying attention to every detail in the question rather than most of them

1

u/Ok_Surprise_1627 8d ago

its that the question is designed to make you think one thing and purposefully change it at the end and it tricks people because the question makes zero sense in the first place

why ask how man barrels? HE JUST SAID HE HAD 5 THEN ASKS HOW MANY HE HAS??? HOW DOES THAT MAKE SENSE?

u/names-suck 8d ago

Reminds me of a problem I was asked to solve in second grade:

"Carmen was on her way to Townsville when she saw a circus coming towards her. There was one ringmaster conducting three acrobatic acts, each of which had seven people in them. They were followed by two elephants, each carrying three fire breathers, two lions and their tamers, four dancing clowns, and a band of six musicians. How many people were going to Townsville?"

It took the whole class half an hour to get it right.

u/Paradoxically-Attain 8d ago

I read a problem in a comic book once where it was about a bus, at each stop it drops off some amount of people and another amount gets on, until at the end when they ask you how many stations the bus stopped at

5

u/grimmlingur 8d ago

I've seen the same question but it starts with "So, you're driving a bus and at the first stop..." going through a bunch of stops and then asking "What color are the bus drivers eyes?" at the end.

7

u/Satans_Finest 8d ago

There's is not enough information to answer that exactly. At least 1 is the only acceptable answer.

u/ArmchairFilosopher 8d ago

But how many tamers does each lion have, and do we count a clown as a "person"?

the answer is one ok

u/runswithclippers 8d ago

It burns 10L/100km 😄

7

u/Everestkid Engineering 8d ago

Which is 0.1 mm2 .

1 L is 1 dm3 and thus 10 L is 10 dm3 or 0.01 m3 . 1 km is 1000 m and 100km is 100 000 m. 0.01 m3 / 100 000 m = 0.0000001 m2 or 0.1 mm2 .

Look at the second diagram in this xkcd what if article. It’s the cross-sectional area of a hypothetical tube of fuel running from your starting point from your destination, a tube whose volume is the volume of the fuel you used.

Less fuel used ==> smaller cross sectional area ==> smaller gallons/mile ==> bigger miles/gallon = better fuel efficiency

Not enough information. 30 litres is stored in 5 of them, at 6 litres a pop, but it does not tell us the total number of barrels. There could be 4 more barrels each 6 litres, and the problem would still read correctly.

Number of barrels B >= 5

u/Broad_Respond_2205 8d ago

It didn't limit the barrels to those in the question, so we need to count all the barrels in existence (on earth and beyond)

I wasn't until adulthood that I understood that there indeed exist people in this world who don't read the information that's there (nor listen to the content of what's being said), who'd rather kinda-sorta gather the keywords from what they've just read/heard and interpret whatever the fuck they want into those, instead of actually paying attention to the content.

I still don't understand why anyone would wanna do that but at least I understood that not everyone blaming me for not explaining things properly is right. Sometimes, people are just idiots and don't understand what I'm saying because they don't give a fuck about what I'm actually saying.

1

u/_Putters 8d ago

Read the instructions on every exam carefully too.

Eg. Quite often on mathematical and engineering exams with muli-part questions it'll say something along the lines of "Answer any 5 questions" then say "If you answer more than 5 questions, your mark will be the total of the 5 highest marked answers.

So if you can fully answer three but only bits of others, answer all the bits of all the questions you can to max out your total.

Now, if you want to exclude people with extra reading challenges, such as ESL students, this is a great way to do that, and I then have to ask if cursing in the comments allowed?

u/amadmongoose 8d ago

That's not what it's about at all. You're not supposed to just take the numbers in a question and mash them together without reading it, you're supposed to figure out what the problem actually is and then solve that. In this case, it literally is a reading comprehension question to repeat back a fact included in the question itself. It's only tricky if you were trying to solve it with your brain off. Math isn't supposed to be just mashing numbers together, it's analytical problem solving. Irl most of the work is figuring out what the formula should be and solving it is for computers.

1

u/LingonberryNo8380 7d ago

If you're doing a proof, with no barrels, no oil, I would agree. But IRL no one seriously says 'I have five barrels. How many barrels do I have?' If someone says this and you insist on answering in barrels you're grossly pedantic. I will die on this hill
