Solution

The correct option is C 62
It can be observed that the total number of observations in the given data is 10 (even number).

Therefore, the median of this data will be the mean of (102)th observation and (102+1) th observation.

Median = 5th observation + 6th observation2

63=x + x + 22

63=2x + 22

63=x+1

x=62
