    Two methods:

    B to the total.

    C points to the total.

    The total is 24 (3 8 7 40) 120 and 120 3 8 45.

    B gets 120 9 20 54 copies.

    C gets 120 7 40 21.

    There are a total of x copies. Then Class A is assigned to 3 8x books, and Class B is assigned to 3 8* books.

    Class C has this book.

    There is x=120

    A gets 120 3 8 45.

    B gets 120 9 20 54 copies.

    C gets 120 7 40 21.

    Answer: Class A gets 45 books, Class B gets 54 books, and Class C gets 21 books.

    24 divided by (1-3 8-3 8-1 5) = 480 (Ben) Class A: 480 * 3 8 = 180 (Ben).

    Class B: 480 * (3 8 + 1 5) = 276 (Ben) Class C: 180-24 = 156 (Ben).

    Suppose that if A and B do not rest, A completes 1 30 (1/30) per day, and B completes 1 40 (1/40) per day, they can be completed in 25 days together:

    And in 25 days they actually completed 1, a total of less completion: 35 24-1 = 11 24 less completed 11 24 because both A and B rested.

    A: The number of days required for B to complete it alone.

    Efficiency. 4:3 (inversely proportional to the number of days required to complete it individually).

    Number of days off.

    2:1 for less completion.

    A is less completed: 11 24 8 11 = 1 3 (proportional) A rests days: 1 3 1 30 = 10 (days) (total work efficiency = working hours).

    Number of days B rests: 10 2 = 5 (days).

    The number of days B breaks can also be found as follows: (the process before the space remains unchanged) B has completed 11 24 3 11 = 1 8 (proportional) B has rested for the number of days: 1 8 1 40 = 5 (days) (total work efficiency = working hours).

    Answer: B took a break for 5 days.
