Solution

The correct option is B

21,23


Given data 21,23,25,23,21,24,22,20,23

The mode is the value that is repeatedly occurring in a given set.

Here 23 is the most repeating data.

Mode = 23

Median is the middle value of the given list of data when arranged in an order (increasing or decreasing ) .

20,21,21,22,23,23,23,24,25

Here number of terms =9 terms (odd)

So median =n+12thterm

=9+12thterm

=5thterm=23

Median= 23

Hence option (B) 23,23 is the answer.
