You are given 9,9,9,9,5,5,5,5,3,3,3,3,1,1,1,1.Now you are supposed to select exactly 6 no.s from the given no.s so that the sum is exactly 21. It's a challenge. If you are a genius reply. 😁

P.S. I don't know the answer.

    Hmm, you are asking us to 'add' six odd numbers to get an odd number?


    Will this work? -> 5 x 3 + 3 + 1 + 1 + 1

    Sum of six odd numbers will be an even number.

    So, the question is wrong.

    You can make 22 using six numbers ==> 5,5,5,3,3,1
    Or, you can make 21 using five ==> 5,5,5,3,3

    I don't know the answer but as far as I know multiplication was not allowed.

    Even I also came to same conclusion and replied same. I guess some one was making me fool . πŸ˜€
