Question 28
The ten students in Malcolm’s maths class all took a test. The scores of the other nine students were 82, 83, 85, 89, 90, 92, 95, 97, and 98, and Malcolm’s score was a whole number.
The teacher had made a mistake in calculating Malcolm’s score. After she corrected her mistake, both the mean and the median of all the scores increased by 0.5.
There are two possible correct scores that Malcolm could have had. What is the sum of these two scores?
