    Answer:

      16 tricycles

      12 bicycles

    Step-by-step explanation:

    If all were bicycles, there would be 28·2 = 56 wheels. Each additional wheel indicates the presence of a tricycle instead of a bicycle.

    There are 72 -56 = 16 tricycles. The remaining 28-16 = 12 are bicycles.
