Show answer & explanation
Correct answer: B
Ravi is at the 21st position from the left end and also at the 21st position from the right end. Adding these two positions counts Ravi himself twice (once from each end).
Total students = (position from left) + (position from right) - 1 = 21 + 21 - 1 = 41.
