    One unsolved Puzzle.

    I think last post was in wrong category

    One of my friend have asked this question last day.

    break "20" into 6 different numbers, the number you'll select will not be double.

    __ + __ + __ + __ + __ + __ = 20

    put words in this __ . blank place

    Rules:

    1) You cannot use any word two times.
    e.g. 1+2+3+4+5+5=20 it is correct but 5 is double time. so it will not acceptable.

    2) word will not in minus (-)

    3) You can use number between 1 to 15.

    4) Do not use 0 (zero).

    If it is impossible, give me the reason too...

    the combination of numbers which gives the minimimum value for their summation would be (1,2,3,4,5,6)

    so the sum of these numbers are equal to 21

    so any combination would give a result which is equal or greater than 21

    so there cannot be an answer

    Again, this does not sound like a "puzzle" to me...
