Ina class, the average score of thirty students on a test is 69. Later on it was found that the score of one student was wrongly read as 88 instead of 58. The actual average score is: |
58 88 69 68 |
68 |
Sum of score of thirty students = 30 x 69 = 2070 Correct sum = 2070 - 88 + 58 = 2040 Actual average = \(\frac{2040}{30}\) = 68 |
