Please read the below given text for solving the question Each question given below has a problem and two statements numbered I and II giving certain information. You have to decide if the information given in the statements is sufficient for answering the problem. Indicate your answer as (a) if the data in the statement I alone is sufficient to answer the question; (b) if the data in the statement II alone is sufficient to answer the question; (c) if the data either in I or II alone are sufficient to answer to question; (d) if the data even in both the statements together are not sufficient to answer the question; (e) if the data in both the statement together are needed.

To find the rank from other end, we need to know the total number of student in the class, so I is sufficient.
Also from II we can conclude that there are 47 students in the class.
So II is also sufficient.
