Thirty-two students took a 50-item Biology test. The average score obtained is 42. The next day, three students who were absent took the test and obtained 35, 39 and 43. What is the average score of the 35 students?

  • Statistics -

    Mean = Sum of scores/number of scores

    42 = Sum of scores/32

    Solve for sum.

    mean = (Sum+35+39=43)/35

    I'll let you do the calculations.
