    Answer:

    The ratio of the number of cows which give milk to the number of cows which don’t = 8:3

    8x + 3x = total cows

    number of cows which don’t give milk =3x = 144

    x = 144/3

    x = 48

    number of cows which give milk = 8x = 48 x 8 = 384

    total cows = 8x + 3x

                     = 384 + 144

                     = 528
