Mean here = Sum of all the elements/Number of elements = 4+5+5+6+7+8+21/7
=56/7 =8 (Mean)
To find the median, arrange in ascending /descending order and then find the middle value.
For even number of terms, middle value is n/2 th term and if there are odd number of terms, the middle value is (n+1)/2 th term.
In this question, it is already arranged in ascending order and the observed middle value is (7+1)/2th term
= 4th term =6
Thus the required difference is 8-6=2 (B)
Hope this helps :)
