well, i know the answer,
i just want to see if anyone will
answer this question.
there are 10 groups of 10 weights.
(so there are 100 weights as a sum)
each weight in 9 of these groups
have weight of 100 grams.
and one of these groups,
contain weights each of 90 grams.
how can we identify which group
of the 10 groups is the one which
has 90grams weights,
BY WEIGHING ONLY ONCE.
I believe the answer is as easy as 1, 2, 3...

I think this is a riddle.. but whatever, can you define "weighing only once"?
Do you mean weighing each one once? Comparing once? ...
Its an actual scale.
Like you step on and it says "You weigh 1 + 2 + 3 + ... + 9 + 10" * 100 minus 10*k, k being the number of 90 ounce weights you placed on the scale.
do rey me,
a, b, c,
1, 2, 3,
its you and me babe....

is it really that easy ??!
it needed some thinking for me !
yes "something else" is correct,
its an actual scale,
which gives the sum of weights placed on it.
does weighing only once mean that you can weigh each one once?
That would sorta make it easy.
Well then put 1 from group 1, 2 from group 2... up to group 9
yeah, thats it :DQuote:
