    12 a.m.

    Step-by-step explanation:

    Just find the LCM or least common multiple of the minute-intervals of their barking. Then, add it to 11 p.m. to know the answer.

    Finding the time when the dogs bark together:

    4(ban): 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 603(tag): 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 605(black): 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60

    They bark together every 60 minutes (1 hour).

    11 p.m. + 1 hour = 12 a.m.

    Solution:

    ted's harvested - his brother's harvested

    (50 3/4) - (38 5/6)

    (203/4) - (233/6)

    lcd: 12

    (609/12) - (466/12)

    143/12

    11 11/12


    answer: 11 11/12 kilos
