Solution
The correct option is D 22 Mode is the value that appears in a given data more often than the others. If two numbers appear maximum no of times we take average of both.
So no of 20's=3
no of 21's=5
no of 22's=7
no of 23's=5
no of 24's=2
no of 25's=1
Since 22 appear more no of times, mode of given data is 22.
