CorrectNot quiteAnswer A

Correct answer: A

Explanation

  1. After the swap Rahul is in Neel's old place, so Neel was 17th from the left.

  2. The two places are 10th and 17th from the left.

  3. Between them =17−10−1=6= 17 - 10 - 1 = 6.

Worth noting

7 is the difference 17−1017 - 10, which counts one of the two. Neel's 13th-from-the-right is not needed for this question; it gives the total, 29.
