A. 20 B. 21 C. 22 D. 25
Answer: B
Solution: It is given that Ram is at 22nd position from left that means the base rank of Ram is given. We are also given the total number of students that is 42.
Rank of Ram from the left end = 22
Total number of students = 42.
To find rank of X from right end = ?
Formula: - Rank of Ram from right end = Total no.of persons - Rank of Ram from left end + 1
Rank of Ram from right end = 42 - 22 + 1 = 20 + 1 = 21
