    Take {rat, cat, dog} as {x, y, z} and solve these equations

    x+y = 10
    x+z = 20
    y+z = 24

    When you solve this you get
    {rat, cat, dog} = {3, 7, 17}

    So to answer the question :
    rat + cat + dog = 3 + 7 + 17 = 27

    You could also add all the equations (as you have not asked the individual weights)

    Add all the 3 equations above :
    you will get
    2x + 2y + 2z = 54
    Divide the equation by 2 :
    x + y + z = 54/2 = 27
    rat + cat + dog = 27
