Correct Answer - Option 2 : 27th and 26th
Total number of students in the class = 39
Rank of Ravi from the top = 13th
Total number of students = Rank of a person from top + Rank of the same person from bottom - 1
So, his rank from the bottom = (39 - 13) + 1
Rank of Kishor from the top = 14th
So, his rank from the bottom = (39 - 14) + 1
Hence, ‘27th and 26th’ is the correct answer.
