Show answer & explanation
Correct answer: D
Key formula: To convert a position from the right end to the left end: left position = total students - right position + 1.
Step 1: Find Ravi's position from the left.
Ravi's left position = 50 - 20 + 1 = 31.
Step 2: Rahul is 15 places to the left of Ravi, so subtract 15 from Ravi's left position.
Rahul's left position = 31 - 15 = 16.
Answer: Rahul is 16th from the left.
