The correct answer is [C]

- The mean of 5 numbers = 9
- The total of the numbers 9 x 5 = 45
- The four numbers =5, 10, 5, 14
- The fifth is x such that 5 + 10 + 5 + 14 + x = 45
34 + x = 45
X = 45-34
X = 11
- The median
Arrange the numbers in ascending order and pick the middle one
5, 5, 10, 11, 14
The correct answer is 10
