Answer:
The sum of five scores that is not the median is, 336

Average defined as the the sum of the observation to the total number of the observation.
Given: The sum of the five scores is 420
Then, by definition of average;
Average of five distinct score =
It is also, given that the average of five distinct scores has the same value as the median of the five scores.
⇒Median of five scores = 84
Since, scores are distinct, therefore
Sum of all scores that is not the median = Sum of five scores - median = 420-84 = 336
therefore, the sum of five scores that is not the median is, 336
