Three boxes of supplies have an average weight of 7kg and a median weight of 9kg. What is the maximum possible weight, in kg, of the lightest box?
A) 1
B) 2
C) 3
D) 4
E) 5
I keep getting B, and the OA is C. This is my reasoning:
If median is 9, then heaviest box must be greater than 9.
(x+9+10)/3 = 7
x +19 = 21
x = 2
