Coffee, Tea or Me

Imagine you have one cup of tea and one cup of coffee.

Place a spoonful of the tea into the coffee and then place a spoonful of the tea/coffee mixture back into the tea.

Does the cup of coffee now contain more tea, or the cup of tea more coffee or are they the same?

    It will be in equal measure, lets presume there is 100 units of tea & coffee to begin with.

    Lets us presume the spoon capacity is 10 units.

    Initial contents:

    Cup T: Tea 100 Units, Coffee 0 Units
    CUP C: Tea 0 Units, Coffee 100 Units

    Transferring one spoonful of tea from Cup T to Cup C:

    Cup T: Tea 90 Units, Coffee 0 Units
    CUP C: Tea 10 Units, Coffee 100 Units

    When we again draw another spoon full of mixture from Cup C in the ratio of its contents as follows:

    Tea – 10/110*10 = 0.91 Units
    Coffee – 100/110*10 = 9.09 Units

    Transferring 1 spoonful of mixture to Cup T:

    Cup T: Tea 90.91 Units (90+.91), Coffee 9.09 Units (0+9.09)
    CUP C: Tea 9.09 Units (10-.91), Coffee 90.91 Units (100-9.09)
