CorrectNot quiteAnswer D

Correct answer: D

Explanation

  1. Bhavesh's rank from the top =18+9=27= 18 + 9 = 27.

  2. Class strength =27+25−1=51= 27 + 25 - 1 = 51.

Worth noting

42 is 18+25−118 + 25 - 1, which uses Anjali's rank from the top with Bhavesh's rank from the bottom; 43 also forgets the −1-1.
