• Averages

In a class of 45 students, a boy is ranked 20th. When two boys joined, his rank was dropped by one. What is his new rank from the end?

1. 25th
2. 26th
3. 28th
4. 27th

Answer

After 2 boys joined, total strength of class = 45 + 2 = 47

As rank was dropped by one from 20th rank, new rank is 21st.

Rank of the boy from the beginning = 21

Number of students below his rank = 47 - 21 = 26

Rank from the end = (47 - 21) + 1 = 27

The correct option is D.
