Nitin is 7 ranks ahead of Joginder in a class of 39. If Joginder's rank is 17th from the last, what is Nitin's rank from the beginning?
Show answer & explanation
Answer: (D) 16th
Explanation
Rank from top = total − rank from bottom + 1 = 23 for Joginder; Nitin is 7 ahead, so 16th.
- (A) Incorrect
Wrong: this ignores that Joginder is 23rd from the top.
- (B) Incorrect
Wrong: this places Nitin 8 ranks ahead, not 7.
- (C) Incorrect
Wrong: this does not match 23 − 7.
- (D) Correct
Correct: Joginder from the top = 39 − 17 + 1 = 23; Nitin = 23 − 7 = 16th.
