Good explaination

If you have a stop at the 500km mark and another at the 750km mark, you can actually deliver 750 bananas. You will have 1500 bananas at the 1st stop and 1000 at the 2nd stop, finally 750 at the market place.

There was no requirement to return to the plantation.

technically this puzzle is camel only eats while carrying bananas, not on the return trip

That was not explained before comming up with the solution. Stupid quiz. Go shmizzle a camel

Yeah, I assumed it wouldn’t eat bananas on the return trip. I got ~833 bananas to market. You get 2000 bananas to 333m, then 1000 bananas to 833, then you lose 167 to the end.

@@timothyn4699Is it? where did it say that in the rules. It says for every km traveled, so it would need to eat them to on return trips too. That's why this doesn't make sense.

@@captbloodbeard it has to be only on trips to, not on return trips. 1) on return trips, camel is not carrying any bananas. How can it eat a banana it does not have (unless it makes up for it and eats a bunch immediately on return) 2) it's impossible to only be able to carry 1000 bananas at a time, need to travel 1000km, and must eat 1 banana/km (both ways), and still have bananas leftover. Think about it, if you carry all of them the whole way, it's all consumed. If you drop it off halfway, you have 500 left. You return 500km back home, your balance is now 0. If you travel 750 km, your balance is 250. You return home another 750km, your balance is -500 bananas. If you travel 250km, your balance is 750, and you still need to go 750km. Returning home only hurts you and drops your bananas down -250, so you have 500 remaining, yet now you need to travel 250 (to get back to where you were, you now have 250 bananas), and still need to travel 750 to market, so you're -500 bananas if you go to market. hence, it must be the case, that camel does not require bananas on return trip (nor binge eat on return back), if the problem is going to make any sense, and if you are to have any bananas leftover

I'm suggesting the amount of energy stored in 50 kg of biological mass would decrease in time, and to use this 50 kg would be better than storing it. It would be more dense (maybe 2 times more dense, but may lose 10%), but less efficient overall.

Yes, draft horses could eat one fourth of the output of the farm.

Agreed, this needs clarification. I just wrote the same paragraph and then checked to see if someone else already wrote it: It is unclear in the description of the problem that the camel MUST eat a banana in order to move 1 km (like it's FUELing the camel), or if it only eats them if they are available (as in a NUISANCE behavior of the camel). In other words, you could assume that if there are no bananas with the camel, it is still able to travel back to the plantation to fetch more bananas.

"the camel is opportunistically stealing a banana every km"-- Lol, even camels are shady in the middle east.

no, the question is fine

100% agreed. Had the same issue. I understood that the camel needed to make multiple drop offs but thought that the return trips didn't require bananas.

And 'it eats one banana for every km it travels' could be clarified to say one needs to be eaten every km, or the camel can eat many at one time to cover the upcoming kms.

Yeah, and that's why we just invented a 3-stage Camel.

When I first saw the question I immediately thought it resembled a rocket equation.

Would make sense when the Profit of the additional 300 Bananas would make up for buying two new camels plus profit

also any transactional and opportunity costs of seeking and purchasing additional camels instead of doing something else with your time and effort, and then dedicating those camels to this trip instead of another task (I'm also going to assume additional transactional costs for selling the camels at each staging point which represents a village that has sprung up at the optimal point between the edge of the viable banana-growth zone and the market in order to sustain the banana-transportation economy, in order to avoid the inhumanity of abandoning a living subservient entity in unsurvivable conditions (and potentially preserve the availability of domesticated camels). I haven't quite finished figuring out what else if anything must be true about additional economic/logistical factors in the economy to justify the upkeep of those villages given that the banana traders are only bringing in a single banana to only one of the two villages each cycle of the trade route. If these villages don't happen to already be at these points for simply being at bodies of water or something else external, there has to be some other reason or incentive for them to exist. Some of the banana merchants are able to amass more than 3000 bananas and there is some sort of cultural custom or economic arrangement that incentivizes them to sell or donate a significant amount of bananas to those villages? Perhaps it's a market saturation issue, where they prefer to sell to the final market on the route because it's more profitable per unit and/or willing to buy the largest bulk of product, but will still sell additional freight to the intermediary markets. Or perhaps the patron making it possible for them to amass more than 3000 bananas per cycle in the first place has done so in order to direct them to transport the bananas to the final market)

You see? Carrying from the next town 10,000 km away from us is cumbersome to say the least. So come there and help us load the cargo.

What I thought after getting zero as answer

We found the dummy, folks!

Then the camel would weigh 1001 bananas and be overburdened, the legs would snap right off 🙄

​@@oyuyuy At point Q, you have the 1001 bananas. You feed one to the camel and load him with 1000. Now the camel needs only 466 bananas to get to the market.

I just tried to replicate this in an Excel sheet. After I came up with a formula, I then copied it down all 1,000 rows - and came up 1 banana short! (I only get 532 bananas to the market.) Then checked what's going on and realized that at kilometer 533 I have 1,001 bananas but I send my camel back to fetch the 1 leftover banana, consuming 2 bananas on the way. _Not_ doing this one trip saves me 2 bananas (for the back and forth trip) but I have to sacrifice that 1 banana, so effectively adds one banana to the final count and thus I also get 533! 😀 In short, I should have accounted for these situations where the camel would go back for only one banana and insert an if-then step into the formula but since this only occurs once, it's not worth it. Anyway, this is really interesting as it raises the question whether the individual trips can be set at an arbitrary length. I guess, it gets more complicated for trips greater than 1 km because these situations where the camel goes back for just one banana need to be avoided lest the sacrificed bananas accumulate.

The reason of why those two are both correct solving in that fact, until first 1000 ends up all those 1 km movements will be the same (3 bananas per km), so all those same steps can be added to each other (e.g. multiplication)

And with 0.9999km Trips, you get all the Bananas over :D

And ask government to put a road.

🤣

r u drunk

Good one! The correct answer would be plant more bananas. And do the trip with 3 drop points (Or buy a truck and sell the camel)😂

@@RoyMatzem No, just get a truck or at least build a cart and let the camel pull it. The real solution is using science. The fact alone how that with this solution on top most bananas will likely be rotten thanks to the wasted time. Pretty sure cour camel got no cooling system installed to keep them fresh enough. A camel can go for around 65km per day. That alone makes just those first 200km a 3x5 = 15 days journey. The next woul dbe around 5x3 days, another 15, so already a full month. Last journey woud at least be a single one so 1x7 days. 37 days for the whole show and that all on a camel back. Not sure how much there will be left from your bananas.

Number 1 was my first thought too. If the camel goes only 999 metres and drops its cargo then it cant eat any bananas :"D Go back, load the other bananas and go 999metres again. Repeat infinite times.

Plot twist : the camel was never intended to make the way back :0

a) 533 b) 833 And if the camel is allowed to eat fractions of banana each meter, a=533.333... and b=833.333... then also c=833.333...

incorrect. only a works

e)3000. My goal is transport 3000 bananas, and since the problem doesnt limit my time, i can plant more bananas until i reach the goal.

The bananas left at the end would be actually 733, but I think it's clear enough that we have only one camel to work with.

And they are a one time use animal, as it can't come back to the farm.

Ever went for a 2000km run?

The problem does state that the camel is eating on the go. "Every Km the camel eats 1 banana" its an anagram for cash spent in logistics, I am transporting x cash of product, but the trip costs x cash to make. How do I make it cost y instead. Where y < x In logistics you do have to transport every single banana, the alternative being you don't sell product, and thus lose money on both product and logistical services.

So if we assume this, you cant stop at 0,9km.

Also maybe you didnt notice, but in his calculation he leaves 1 banana at point Q

But it wrote 'camel' right? And the better answer is 2000 banana

Tamrin Kesambi the question does not state how many camels you can use

Minor correction, the camel only eats one banana every one kilometer. So there is no decimal.

If you listen to the video he says “a camel”.

No!! Will you just abandon your camels?? Thats a very great loss.....

another decent comment... respect to you Rama

Yeah, because they never state in the problem that you're allowed to do this. If you can introduce arbitrary information or conditions then you can resolve this problem an infinite number of ways. And you can't say it's common sense or intuitive because a camel can't carry 1,000 bananas due to their weight, and camels aren't powered by bananas. It's a stupid question.

@@BuceGar Yes. The most illogical part of this supposedly logical puzzle is how the camel needs a banana every 1 km on the way to the market, but on the way back, it can travel even the whole 1000 km without eating a single one. I kind of expected that we forget about needing the food for camel at the very end, for the final trip home (guess we can pretend the seller sells his animal at the market, when he has no more bananas), but not that moving back and forth in the middle of solving the puzzle somehow requires bananas when going from A to B, but no when going from B to A.

@@ArCgon You should perhaps watch the video again. You're right that there's no word of what's to happen after the camel reaches the market, and that's besides the point, but the camel does eat when it goes back to get more bananas. Here's a quick rundown of the trips from starting point to first waypoint: The distance to the first waypoint is 200 km, so the camel picks up 1000 bananas, eats 200 on the way to the checkpoint and another 200 on the way back. You're back at the starting point but you have 600 bananas already partway through. Repeat it and you have 1200. On the third trip you've emptied the starting point so you get to keep 800, leaving you at 2000, like stated.

@@BuceGar This. Introducing a condition like this changes the nature of the problem and its solution, so it's important for the question to specify. Bad question design.

Agree that assuming you are going to have 1000 bananas at the last drop point is to some extent assuming the conclusion. You need to prove that there isn't some benefit to be had by just "sacrificing" some bananas to some other consideration, and having, for example, a drop point with only 800 bananas that is over 200km closer to the destination.

Here's how I would rigorize this solution (sketch): Claim 1: It never makes sense to leave bananas behind. (For example if you start with 3007 bananas, you can move the 3000 banana pile 1km forward instead of ditching the 7 bananas) 2: Suppose we travel west to east. Then if I tell you how many times the camel travels eastbound over each spot X, then the total number of bananas you get in the end is the same regardless of the specific path taken. The total number of bananas traveling eastbound over X is > 1000n (n is an integer) and

🤓

Here's a few quick observations that might help analysis: - _You_ need to travel to market. This establishes a fixed minimum cost of 1000 bananas (one way). Any additional "roundtrips" (say, to carry some bananas to an intermediate drop point then return) will cost 2 bananas per km.

Car will consume banana if it run out of oil.

@@marvinkitfox3386 sell the camel, keep the economy running XD

No, the total distance traveled by the camel is INCREASED, significantly. What’s increased is the number of bananas available for it to eat during the trip. The multiple trips make all 3000 available, not just the 1000 it can carry at one time.

You're wrong. Y is 333km, because it can't be fractaled

It's basically a semantical problem. As long as you don't account the 0.33 of a banana in it's stomach towards it's carrying capacity, there isn't a problem going 333.33km. Even if you did count this towards the carrying capacity, you would also need to feed the camel before each km, and not after each km. eating AFTER each full km would mean you never exceed capacity, as a 334th banana is ate from 1000 stock of the final 333.33km trip) 333+333+334=1000 consumed eating BEFORE each km you *would* actually get 533 bananas, but only because you need a full banana for the last 0.66km of the 466.66km trip, whereas eating after, you are able to get the 0.66km for "free" At the beginning (00:26) it is stated that "it eats one banana for every km it travels", to me this clearly means it only eats after the completion of a km.

@@oyuyuy .

​@@oyuyuythe bananas can't be done in fractions in this problem, but the distance can. The camel isn't taking 1km long strides.

​@oyuyuy Of course, bananas can be fractional. Never shared a banana before? But that isn't relevant. It just means that the camel doesn't have to eat a banana every time it gets to point Q, which is fine. Nothing says that points P or Q have to also line up with camel feeding points. What if the camel ate 3 bananas every pi km travelled? That should make it obvious that the consumption rate of bananas does not have to line up with stopping points. Also, it is okay if it finishes the trip slightly hungry, so eating 1 banana every km vs something like 5 every 5 km makes a difference in how many bananas make it to market as well. So I agree that the correct answer is 534. Moving point Q unnecessarily to make it 1001 km away makes 533 suboptimal.

For that also you have to go to the market 😅

And lose 1000 bananas in the process

@@afelix lol 😂😂🤣🤣

That's not part of the problem. It says that the camel eats 1 per km, not that it has to in order to survive.

​@@jttech44No, you are phantasizing concessions that aren't provided. If it needs 1 banana / km travelled, then it will need 1000 bananas to get home from the market. Otherwise it would not have needed them on the return trips from the caches either, *obviously*. Otherwise it would be the first camel with an unidirectional eating habit. Without selling (or abandoning) the camel at the market, no bananas can be delivered this distance (and returning with the camel). In fact, even with the optimal solution, and no sale at the market the camel would die (or stop) 466 km from home, obviously. So the optimal solution is not to depart. Unless you intend to sell the camel along with the banans.

@@Flexximilian my solution is within the bounds of the game. Don't hate the player, hate the game.

It's possible only in math world. In real world, if the camel needs to eat a banana to travel 1km, then it dies on the way back from those short trip and you are out a camel as well as all the bananas.

The puzzle fails to state that the camel only needs to eat bananas while carrying them, or that it only eats bananas while they are available and the plantation owner is somehow incapable of putting a muzzel on the camel

I took three camels, and one the load was down to 2000 bananas put them all on two and cut the third loose. Once down to 1000 bananas put them all on the last camel and cut the other one loose.

@@mikespangler98 The question constrains us to use 1 camel only. Otherwise your suggestion would indeed be more efficient, since it cuts down on the back&force travels.

time is not a factor cause you can't get any profit if u save time plus replace banana with potatoes etc.....hope u got my point

NiVi Rajput not only do you sell 350 bananas but you then have to buy 1000 bananas to make the trip home with your camel. So you’re now dome 650 banana dollars. Mental.

That's why yahoo is out of business

Except that as there’s no point at which it says you can do intermediate trips, I will assume that I have a giant catapult and can catapult all 3000 bananas to the market with a loss of 10% of bananas due to damage. So that 2700 bananas will be delivered successfully to the market.

Logically you want to return home riding your camel, and you only have 533 bananas left?

When we work with optimization, we approach towards the best value, then make adjustments if required... First we calculate the value of Y = 333.33... but due to it's fractional value we either have to adjust it to 333 or to 334. Since the segment PQ has 3 trips, so it's better to have lower distance value from the two options... so we chose 333. If suppose you take 334, then you get 998 on point Q, then 532 bananas will be delivered to the market.

LOGICALLY YOURS but you haven’t proven that those choices are the most optimal. That would require calculus.

@@LOGICALLYYOURS Why do you have to adjust for a fractional value at this point? i get it would make no difference in the end as you probably cant sell a banana that a camel has eaten 1/3 of but at point Q the camel could be part way through a banana and finish it off on its way back to point P

Here's a quick solution just to show that using two camels we can deliver more than 533. P.S. : I can further optimize it to get around 600... but I just wanted to quickly show this. Camel1 - Carries 1000 and travels 750 km.... we get 250 bananas at point P. Camel2 - For remaining 2000, it travels 333 km and manages to bring 1001 banans at point Q. Camel2 - From Q to P its (750-333)=417 km... so out of 1000 Camel 2 eats 417 and delivers 583 bananas to point P. Point P now has : (250+583) = 833 ... distance remaining to market is 250km... So, any camel can now travel carrying the remaining bananas and deliver 583 bananas to the market.... Again I'd like to mention, that by shifting point P towards left a little, we can try to increase the output a bit more. I will calculate it and update later.
