You can put this solution on YOUR website! The average arithmetic mean of (k) scores is 20 .
The average of 10 of these scores is 15.
Find the average of the remaining scores in terms of (k)
------------
average = (total points)/(# of numbers)
-----------------
20 = (total pts)/k
total pts = 20k
-----------------------------
Average of 10 of the scores
pts = 10*15 = 150
--------------------------
Average of the remaining k-10 scores
ave = (20k-150)/(k-10)
