Correct Answer - Option 3 : 25
th
Total students in a class = 42
Rank of Divya from the start = 26th
Rank of Bharati from the start = 26 - 8 = 18th
Total students in a class = Rank of Bharati from the start + Rank of Bharati from the last - 1
Rank of Bharati from the last = Total students in a class - Rank of Bharati from the start + 1
Rank of Bharati from the last = 42 - 18 + 1 = 25th
Hence, 25th is correct.
