    Answer: 4

    Step-by-step explanation:

    In the question it says: the number of her classmates who like sports:

    80 * 65%= 52

    The number of her relatives who like sports:

    64*75%=48

    So, 52 – 48 = 4

    Answer:

    65%×80=52

    (80-52=28) no of classmates who liked sports

    75%×64=48

    (64-48=16) no of relatives who liked sports

    no of classmates who liked sports – no of relatives who liked sports

    = 28-16 = 12

    Hence, 12 more of her classmates like sports as compared to her relatives
