    A father is 4 times as old as his son. In 20 years the father will be twice as old as his son. Find the present age of each.
    Just convert to algebra and the answer falls out.
    If the father has age F and the son has age S, then clearly F = 4S. What will be their ages in twenty years, and what algebraic relationship can you derive from that?

    Technically it wasn't a full solution, his wasn't the final answer.
