    Hello, Kim!

    Please check your post for typos.
    The problems make no sense . . .



    1) This number is a multiple of 9
    . . This number is Prime . . . .
    What?
    . . This number is a multiple of 35
    . . This number is a multiple of 25
    . . What number am I?

    If the number is a multiple of 9, it cannot be a prime.




    2) This number is NOT a factor of 100
    . . This number is a factor of 70
    . . This number is a factor of 60
    . . One factor of this number is 4
    . . What number am I?
    Let N be the number.

    Factors of 100:. . 1, 2, 4, 5, 10, 20, 25, 50, 100
    . . N is not any of these numbers.

    Factors of 70: . {\color{red}\rlap{/}}1, {\color{red}\rlap{/}}2, {\color{red}\rlap{/}}5, 7, {\color{red}\rlap{//}}10, 14, 35, 70

    Factors of 60: . {\color{red}\rlap{/}}1, {\color{red}\rlap{/}}2,3,{\color{red}\rlap{/}}4,{\color{red}\rlap{/}}5,6,{\color{red}\rlap{//}}10,12,15,{\color{red}\rlap{//}}20,30,60


    But there is no number which is a factor of 70 and a factor of 60.




    3) This number is less than 30
    . . This number is greater than 20
    . . The sum of the digits in this number is 20 .
    Impossible!
    . . This number is greater than 5 .
    Well. duh!
    . . What number am I?

    1. Possible answer to what? Quote what you're refering to so that your posts makes sense.

    2. Go back and read what Soroban has said. None of the questions you posted make sense.
