Ball Puzzle

on Monday, 9 July 2012
This puzzle is asked in most of the interview questions and sounds tough whenever you hear it first time.
There are 10 buckets each containing 100 small balls weighing 1 gram except the one bucket which contains balls weighing 0.9 gram. All the balls are of same colour and looks same. You are given a weighing machine which displays the weight in grams. You have to use it only once and you have to find out which bucket contains 0.9 gram balls.
