    Answer:

    The correct answer is third option 3 : 4

    Step-by-step explanation:

    It is given that,Jamaal has 20 models of planes and cars

    Also he has  three times as many cars as planes

    Let ‘x’ be the number planes.

    Then number of cars = 3x

    Total number of models = x + 3x = 4x

    To find the ratio of his cars to total models

    cars : total models = 3x : 4x

     = 3 : 4

    Therefore the correct answer is third option 3 : 4
