    Mike has $20, Todd initially has $21. Todd keeps all his money on the table between them. Hence, now Todd has nothing, Mike has $20 more than Todd, and they have $21 between them i.e on the table between them.

    Uhh, the previous solution is completely wrong.

    This can be done really easily using algebra -

    Mike = $20 + Todd (1)
    Mike + Todd = $21 (2)
    Substitute for Mike in equation (2)
    $20 + 2*Todd = $21
    Todd = $0.50

    No fractions.... Okay, one has fifty cents -- the other has fifty cents and twenty dollars.

    Mike = 20 + Todd
    Mike + Todd = 2 * 21

    Solving them
    Mike = 31
    Todd = 11

    Mike has $20, and both Mike and Todd has $1 in share. Mike is $20 more than Todd and in total they have $21.
