    Input (m,n) output...

    Starting with the input (m,n), Machine A gives the output (n,m)
    Starting with the input (m,n), Machine B gives the output (m+3n,n)
    Starting with the input (m,n), Machine C gives the output (m-2n,n)
    Starting with the pair (0,1) which of the following is impossible to obtain after using the machines any number of times ?

    A. (2009,1016)
    B. (2009,1004)
    C. (2009,1002)
    D. (2009,1008)
    E. (2009,1032)

    Thank you in advance

    None are possible as stated.
    Machine A (0,1) will always yield (1,0).
    If you entered (0,1) several million times you expect (1,0) to result.


    Do you intend for the output of machine A to be the input for machine B?
    Machine B output to be the input for machine C & machine C output to be the input for A?

    Or
    Is the output of machine A supposed to be the input for the next cycle of machine A?

    It is not clear.

    Actually, it looks like a trick question.

    So for example with (0,1) I use machine B

    (0,1)
    = (3,1)

    Then I use machine A

    (3,1) becomes (1,3).
