Correct answer: B
Concept
When one person’s ranks from the top and bottom are both known, that person is counted in both ranks. Therefore, total people = rank from top + rank from bottom − 1.
Application
Bipasha’s rank from the top is 13 and her rank from the bottom is 5.
Add the two ranks: 13 + 5 = 18.
Subtract 1 because Bipasha was counted twice: 18 − 1 = 17.
Cross-check
If there are 17 students and Bipasha is 13th from the top, then 17 − 13 = 4 students are below her. Including Bipasha gives a rank of 5th from the bottom, which agrees with the given information. Hence, the class has 17 students.
