- two same size glasses, one filled with beer other one with wine
- i do one spoon of the wine in the beer and stir it
- then i do one spoon of that back in the wine

do i have now more beer in the 'wine-glass' or more wine in the 'beer-glass'?

[Tito]

you got more wine in the beer glass

becuase the other spoon was a mixture  :dontknow:

[sputnik]

Equal of both. say that 1 litre = 100, and the spoon (can be any size smaller than 100) is 10.

100B              100W
100B 10W       90W -spoon of wine in beer.
90.90B 9.09W  90.90W 9.09B- spoon of mixture in Beer.

equal.

equal

[Sander]

exactly guys it's equal. after transferring the drinks you still have two glasses with one litre. that means that the beer you miss will be filled up by the wine you miss in the other glass. and also the other way around. so as long as you have two equal amounts it will always stay the same ;)

and i'd like others to post riddles too. i also like to solve them  :cheers:

Maybe too easy for some, but here we go with a small one:

How can you throw a ball as hard as you can and have it come back to you, even if it doesn't hit anything, there is nothing attached to it, and no one else catches or throws it?

i've seen it, great day in my BF carreer. our thread in the top 10 and me in the top 10 posters :'( i'm emotional now

but sven because you did a easy one i'll do a hard(?) one

you are in a tv-show and you have 3 doors you can choose from. behind 2 of them is a goat, the other one will give you so much money you'll never have to work for the rest of your life. you choose one door. the tv-presenter (he knows where the price is) opens one of the other 2 doors where a goat is. he says you have the possibility to change doors now. is it wiser for you to pick the remainder door or to stay with the one you picked first?

+explain why you think it's wiser to change doors, or to not change doors :dontknow: because I know this one ;)
In fact it isn't really a riddle, it's some kind of mathematical problem, or I don't know how to call it.

[TAHA95]

i  cant explain ,but i'd say go in the first one.
