You sit on ESOC all day puzzling! You know nothing of hard life!

Post by Gendarme »

Behold, the ultimate puzzling thread. To write a puzzle, you must solve a previous unsolved puzzle, and if you solve a previous unsolved puzzle, you must write another puzzle. Puzzle solutions and puzzles shall be written in the same post, with the solution to the previous puzzle first (with the puzzle quoted), and your own puzzle afterwards.

Like this, we shall all be entertained while simultaneously building a great database of incredible puzzles (So keep the puzzles appropriate! Not too far-fetched, hard, or solvable only by certain persons). Since this forum is not built for this kind of thing, we have to have some kind of laissez-faire principle - not being too strict with the rules, since it would clutter the thread too much, but try your best to stick to the rules.

Note that your solution need not be correct to write your own puzzle (as it would be too hard to enforce that rule), so if a puzzle has a wrong solution, it is still open to be solved. This means that the amount of puzzles open to solution will increase, so the quality of puzzles will hopefully rise (natural selection at its finest).

Here is the first puzzle of this thread:

You are Superman, and you are exploring The Milky Way. You find a planet that is incredibly similar to Earth, the same size but it is perfectly spherical. You decide to take a very long rope, and lay it around the equator of the planet one complete lap so you have a circle of rope, then you burn the extra rope you have (you little arsonist). You then decide that it would look much nicer if the rope was one meter above the ground all around the equator, but you don't have any more rope, so you have to travel back to Earth and buy some rope, but since rope is extremely expensive, you want to buy the precise amount of extra rope needed to accomplish what you need.

Assuming that you can attach ropes without having to tie knots, how much rope do you need to buy?

wouldn't it just be [Pi * (d + 2m)] - [Pi * d] = x amount of rope ?? Idk the diameter of the earth in meters, as the answer would change with that diameter. Idk. Done with riddles for the night, never been good with em

@sircallen solved my puzzle, but has trouble finding a riddle, so I offered to write in his place and he accepted (this thread is having a rough start).

This puzzle was discussed earlier in Kaiserklein's Twitch-chat, so some might already know the answer:

You have two identical cups: one to the left, half-filled with water, and one to the right, half-filled with pure alcohol. You proceed to take a spoonful of liquid from the left cup and pour into the right cup (and thoroughly mixing), and then take a spoonful of liquid from the right cup, and pour back to the left cup.

Assuming the liquids do not evaporate, which cup contains the most of its original liquid?

Einstein's riddle

The situation

There are 5 houses in five different colors.
In each house lives a person with a different nationality.
These five owners drink a certain type of beverage, smoke a certain brand of cigar and keep a certain pet.
No owners have the same pet, smoke the same brand of cigar or drink the same beverage.
The question is : Who owns the fish?

Hints

the Brit lives in the red house
the Swede keeps dogs as pets
the Dane drinks tea
the green house is on the left of the white house
the green house's owner drinks coffee
the person who smokes Pall Mall rears birds
the owner of the yellow house smokes Dunhill
the man living in the center house drinks milk
the Norwegian lives in the first house
the man who smokes blends lives next to the one who keeps cats
the man who keeps horses lives next to the man who smokes Dunhill
the owner who smokes BlueMaster drinks beer
the German smokes Prince
the Norwegian lives next to the blue house
the man who smokes blend has a neighbor who drinks water
Einstein wrote this riddle this century. He said that 98% of the world could not solve it.

Yeah I did this in class. It's the German easy.

My riddle is this:

On Bagshot Island, there is an airport. The airport is the home-base of an unlimited number of identical airplanes. Each airplane has a fuel capacity to allow it to fly exactly 1/2 way around the world, along a great circle. The planes have the ability to refuel in flight without loss of speed or spillage of fuel. Though the fuel is unlimited, the island is the only source of fuel.
What is the fewest number of aircraft necessary to get one plane all the way around the world assuming that all of the aircraft must return safely to the airport? How did you get to your answer?
Notes:
(a) Each airplane must depart and return to the same airport, and that is the only airport they can land and refuel on ground.
(b) Each airplane must have enough fuel to return to airport.
(c) The time and fuel consumption of refueling can be ignored. (so we can also assume that one airplane can refuel more than one airplanes in air at the same time.)
(d) The amount of fuel airplanes carrying can be zero as long as the other airplane is refueling these airplanes. What is the fewest number of airplanes and number of tanks of fuel needed to accomplish this work? (we only need airplane to go around the world)

Three airplanes (including the one going around the planet), with two refuels - is my guess.

The airplane flies 1/4 of the way, then gets a full refuel from another airplane which then flies back with its remaining fuel. With the full refuel the plane can fly 1/2 more, so when it reaches 3/4 of the way, it is out of fuel, but then the same thing happens, but this time the plane flies the other way around the planet to reach the plane and give it enough fuel for them both to fly 1/4 of a lap to the airport.

My puzzle:

You have a watermelon with the mass of 2 kg. 99% of the watermelon consists of water. One day you leave it out in the sun when going to work, and when you come back home, some water has evaporated and now only 98% of the watermelon consists of water.

What is the mass of the watermelon now?

I just wanted to say that a perfectly spherical earth planet is covered in only ocean.

That is not an issue. The ropes have an incredibly low density while still being strong like Jerom.

Give it a try. It is rather simple; the answer is the real punchline (just like my first riddle where you only needed 6.28 meters additional rope even though the rope's going around the whole planet).

So the only possibly 'correct' answer is 2 kgs. I guess the argumentation would be that the evaporated water is still part of the melon but then it kinda still would be water so that doesnt really work out.

Id protest against any other outcome.

Of course it is not 2 kg. I would never post such a dishonest puzzle.

Well if 99% of the melon consists out if water that doesnt mean we know anything because its unclear how much mass that represents. The 1% could be air or lead and thus have wildly different masses. We dont really know how large the melon is or anything so I am confused.

It is 99% of the mass, or course. Not 99% of the volume.

The answer is 1 kg I think. Turns out you shouldnt leave your watermelon in the sun.
