Another unsolved problem, which i heard on physics courses at school: noone before couldn`t made computer model of "trajectory of mutual movement of three bodies" (or four bodies, don`t remember at the moment...)

Ok, now a real accessible enigma, for everybody who want to solve it.

They are 100 monks who never speak or communicate to each other in anyway. During the day, the monk see all the others, but can't speak or communicate with the other one's. Monday, early in the morning, a badnews come at the monastery. At least one of the monks is sick. The sickness is not contagious. A monk which is certain that he is sick will kill himself during the night. The only visible sign of this sickness is that there is a red button (or spot, or something like that, don't know the exact translation) on his face. The next monday, all the sick monk(s) is/are dead, the other are still alive.

How many monks were sick?
How that happens??

Good luck in this new enigma...

well... I think only one of them was sick and he is the one, who is alive:)..
WHY:
Because news can only SPREAD, if they SEE the red spot (as they dont talk to each other).. So, 99 monks have SEEN the red spot on that guy's face, but, of course, could not tell him.. Supposing, that they didnt have mirrors - they all thought, that they could be sick, as well, so they killed themselves.. While the really sick monk DID NOT SEE any of the spots, so had no reasons to worry and kill himself... But I dont really understand why it is MONDAY :)..

No, i don't think it is the right answer. And yes, I forgot to mention that those monk don't have any mirror. :D
But themonks kill themselves (or commit suicide, don't know exactly how to say that) only if they are certain that they are sick. So a monk seing a red point on another one can just think: "maybe I'm sick, maybe not" thus he is not sure about it's health.

But the monk who don't see any any red point know that he has one on his face, because there is a least one sick monk, and thus he will commit suicide during the next night.

That is the spirit of the enigma. But one sick person, it's to easy, and don't care about some information in the enigma... (I don't know the answer, i just found this enigma on the web, and while trying to solve it, i finally found a solution who take care of all information in the enigma, so i assume it is the right one...)

Try something else :)

well... Ok... but as they dont know the exact number, they can never be sure:).. because if there are two - they will see each others spots, but will not worry about themselves... as there might be just one sick monk..

OR... if there is one - they all die on the second night:).. because on the first night the sick one kills himself, as he doesnt see any other spots, and the others will kill themselves afterwards, as THEY will not see any other red spots...

it's pure logical problem...
But i have some trouble to explain my reasonnement in english lol.
Just I imagine the scene and the answer is logical for me.

A monk see if a monk is sick or not.

Imagine, one monk is sick :
a monk sees nobody who is sick, he's kill himself. (At least one monk is sick)
a monk see a monk who is sick, he knows he's not sick so he don't commit suicide. Find the sick monk takes one day.

Imagine, two monk are sick :
Sick monk sees one sick monk. So the next day, if a sick monk(1) see again the previous sick monk(2), he knows that he was sick the next day. Why? Because monk (1) and monk (2) are not commit suicide on day 1. because they saw one sick monk. So, on day 2, they commit suicide together...

We know that all sick monks are dead on the next monday. So, I think there are 8 sick monks...

Correct reasonment, but i personnlay think that the answer is 7. It's depends if we consider the monk kill themselves during the night between Sunday and Monday, or between Monday and Tuesday...

Nice work Cynyx

Ok.. there is a very very old one, so somebody might know the answer... and its very easy, anyway:)...
A man has 1000 coins and 10 bags, but once he put some money in the bag, he can not open it, so he can only pay with the full bags, and, of course, he wouldnt want to pay more than he needs. So, how put the money into the bags, so he can pay any amount using the bags, without opening them?..

Not sure it is the right way of doing it, but 1024=2^10
So
  • bag 1 : 2^0=1 coin
    bag 2 : 2^1 = 2 coins
    bag 3 : 2^2 = 4 coins
    bag 4 : 2^3 = 8 coins
    bag 5 : 2^4 = 16 coins
    bag 6 : 2^5 = 32 coins
    bag 7 : 2^6 = 64 coins
    bag 8 : 2^7 = 128 coins
    bag 9 : 2^8 = 256 coins
    bag 10 : the remainings coins: 1000-511 = 489 coins
This coins repartition allow you to pay each amount of coins, as soon as you know how many coins are in each bags...

Ok, another very easy enigma:

Three poor guy's come to a cheap hotel and ask for a 3 rooms where they can sleep. The Motel owner ask them 10 € for each room. Thus, the three man paid a total of 30€. The guys come to their respective rooms, but soon the cleanng lady come to their doors. The price for tree room is only 25€, so teh owner asked to the cleaning lady to give back 5€. But 5 isn't a multiple of 3, so the cleaning lady decided to give back 3€, and she puts the 2 remaining s in his pocket.

So we can write (10-1)*3 +2 = 30. Thus 29 = 30.

WTF??? :D

I can't understand when we can write that formula. For me, there is no moment where (10-1)*3+2 describes the situation.

Total amount of money : 30
there are owner, guys and lady.

-> they pay the room
owner 30 guys 0 lady 0
-> the owner payback
owner 25 guys 0 lady 5
-> lady send money back and keep some
owner 25 guys 3 lady 2

At all the time, the sum is 30... and no situation describes (10-1)*3+2 ... this formula is wrong i think.

Perhaps an answer :
-> a cock can't give eggs
-> a barrel has no corner
-> only one egg for a ckicken in one time
-> and the golden chicken don't exist !
