    Here is a very simple way:
    Ratio of
    bulding A: building B = 3:2 = 3x:2x

    then 5x = 60
    x = 12

    3x = 36 ---> building A
    2x = 24 ---> building B

    Just realized it said "elementary" so I don't know if you know how to work with variables.
    Here is another way

    Bld A Bld B Total
    3 .. 2 .. 5
    6 .. 4 .. 10
    12 .. 8 .. 20
    24 .. 16 .. 40
    30 .. 20 .. 50
    36 .. 24 .. 60

    notice 3/2 = 6/4 = ... = 36/24

    Building A has 24 and B has 36. EASY DUDE chagol
