Hello Every Body, i hope u all in perfect situations


Iam not really good in introduction so i'll go straight in the point
this topic is about "why" and its about small quizs

i ask something and u think about the answer and the One who hit it right
will ask another and so on....after one day i'll answer if no1 knws the answer ^^ good luck

i HOPE U'LL ENJOY THE GAME
but stick this to ur mind [all in english], lets start

We have 10 Bottles all filled with coins
and Each COIN is 10gm wieght
Except for one Bottle, the wiegth of the coins in that bottle
is only about 9gm, how we can select this bottle
?

External Help: there is a Balance and we can Use it Only Once

I think by measuring the level of water
and the one that has a lower level is the one with the 9gm

am I right?l

it seemes that no1 can solve the question so i'll solve it since mora than one day has passed
SOL:
first, we get one coin from the first bottle, 2 coins from the second, three from the third, and so on....now we have 55 coins
1+2+3+4+5+6+7+8+9+10=55
each coins supposed to be 10gm so the weight of the 55 coins is 550
we'll put them on the balance and then check the weight, if the weight said 547 then there are three grams missing which means the bottle no3, if the weight is 545 then there are 5gms missing which means the bottle no5.....and so on

i hope u like it...i'll put another one soon
