Well, this is a stem and leaf problem.
The numbers are 20, 28, 29, 29, 31, 32, 36, 41, and 42.
In order to solve for the mean, we find the average and we add the numbers together and divide by 9(there are 9 numbers).
The mean is 32.
The median is the middle number, or 31.

Answer:
(A)
Step-by-step explanation:
Given a set with "n" number of elements, the collection of all subsets of the set is referred to as the Power set of the given set.
To find the number of possible subsets of any set, we use the formula: 
Take for example the set: A={2,3,4)
A has 3 elements, therefore n=3
The number of possible subsets of A is: 
Let one no. be x , Then according to question other number will be 8x
Now 8x - x = 70
7x = 70
x=10
hence one no is 10 and other 80
