Given:
Median of 7 number is x
Formula used:
Median of odd number =
Solution:
Numbers are;
=> 9, 11 , 15, 17, x, 19, 21
Total number are = 7
=> Median = = = 4th term
So median will be 4th term;
On rearranging the terms, we get;
=> Series = 9, 11, 15, x, 17, 19, 21
As we arrange it in ascending order
=> 15 < x < 17
So, only possible value of x is 16
=> Hence, the answer is (c).
