1 Answer

  • The correct answer would be option A, 37.25

    If the average weight of section A is 40 lbs and that of section B is 35 lbs. The average total weight of the whole class is 37.25

    Explanation:

    No of students in section A=36

    No of students in section B=44

    Average Weight of students of section A=40 lbs

    Average Weight of students of section B=35 lbs

    Total no of students in section A and B = (36 + 44) = 80 Students

    Total weight of students in Section A=36*40=1440 lbs

    Total weight of students in Section B=44*35=1540 lbs

    Total weight of the Students in Section A and B = 1440+1540 = 2980 lbs

    Therefore average weight of the whole class,

    = 2980/80

    Average weight of the whole class = 37.25 lbs.
