The series is 1,2,3,4,6,7,8,25,25
So the mean is 81/9=9

Based on the data the set could be
a. 1,2,3,4,6,7,8,9,25
b. 1,3,4,5,6,11,15,18,25
c. 1,2,4,5,6,25,25,25,25

For the least possible mean of the distribution, only option (a) of yours would do, but you will have to correct it first; like 1, 2, 3, 4, 6, 7, 8, 25, 25. Hence the least possible mean of the distribution is [spoiler]9[/spoiler]. All correct thephoenix.
