• A. If the data in statement I alone are sufficient to answer the question
• B. If the data in statement II alone are sufficient answer the question
• C. If the data either in I or II alone are sufficient to answer the question;
• D. If the data even in both the statements together are not sufficient to answer the question

Answer 1

Answer: (C)

If the data either in I or II alone are sufficient to answer the question;

From Statement I, we can conclude that Gaurav's rank from the last is $47+1-18$ = $30$

From Statement II, we can conclude that total no. of students in the class is:

$10+38-1$ = $47$ and thus we can know Gaurav's rank rom the last in a class of $47$ students.

so either of the statement is sufficient to answer the question.

option C
