The average marks of a student in six subjects is 94. After re-evaluation in three
subjects the marks were changed to 89 from 75, 90 from 82 and 88 from 80. In the
remaining subjects, the marks remained unchanged. Find the new average marks.
Correct Answer:
A. 99
Explanation:
The student's initial total marks for six subjects were 564, based on an average of 94. The re-evaluation resulted in a total increase of 30 marks: 14 marks from the first subject (89 minus 75), 8 marks from the second (90 minus 82), and 8 marks from the third (88 minus 80). Adding this increase to the original total results in 594 marks. Dividing the new total of 594 by the six subjects gives a revised average of 99.
