Question 489608
The mean of 10 scores is 14.
---
Sum of the 10 scores is 10*14 = 140
---------------------- 
Another 2 scores are included and the new mean is 16. 
Sum of the 12 scores is 12*16 = 192
-----------------------

What is the mean of the two new scores?
Sum of the scores of the 2 added scores = 192-140 = 52
-----------
Average of the 2 added scores = 52/2 = 26
