    Answer:

      100

    Step-by-step explanation:

    Suppose there are 2n+1 students in the class. If n+1 of them score 91, and n of them score the high score h, for the average to be 95, we must have …

      91(n+1) +nh = 95(2n+1)

      91n +91 +nh = 190n +95

      nh = 99n +4

      h = 99 +4/n

    The high score must be greater than 99. The high score must be 100.
