Question #N460
The average of 5 numbers is 12. If 4 of the numbers are 10, 11, 13, and 14, what is the fifth number?
A. 4
B. 8
C. 12
D. 16
Correct Answer is: D
The sum of the 5 numbers is 5 * 12 = 60. The sum of the first 4 numbers is 10 + 11 + 13 + 14 = 48. Therefore, the fifth number is 60 - 48 = 12.
