Question 1025916
the mean of 12 test scores is 81. when the highest and lowest scores are removed the new mean is 84. if the highest of 12 scores is 98 what is the lowest score 
-----
Original DATA: 
Total scores = 12*81 = 972
----
New DATA:
Total scores = 12*84 = 1008
=====
Let lowest be "x"::
x + 10*81 + 98 = 1008
-----
x + 810 = 900
x = 90
