    Weighing

    There are 10 bags....each containing 10 gold coins.
    there is only one bag in which all gold coins are defected(defected coin's weight can be less than or more than a normal gold coin's weight).
    you know the weight(value) of a normal coin.
    you are given a digital weghing machine. using that machine only once( you can weigh only once), how can you tell which bag has defected coins?

    hi smart coder,

    took 1 from first bag, 2 from second bag, 3 from third bag,......upto 10th bag.

    Now weight these all coins...

    You know the weight of normal coin. so if its one weight less then it should be first bag. two weight less then it should be second bag and so on...

    Your Statement :
    "there is only one bag in which all gold coins are defected(defected coin's weight can be less than or more than a normal gold coin's weight).
    you know the weight(value) of a normal coin."

    i am not assuming initially. According to your question whatever will come. so i assume i got a less weight answer.
