Question

I. There are 73 students in his class.

II. Ashwin, who ranks 25th in Raghu's class is 49th from the last.

• A. If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question
• B. If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question
• C. If the data either in statement I alone or in statement II alone are sufficient to answer the question
• D. If the data in both statements I and II together are necessary to answer the question

Answer 1

The correct option is C

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

From Statement I, Raghu's rank from the last = 73 − 18 + 1 = 56th

From Statement II, we can calculate the total number of students in the class = 25 + 49 − 1=73.

So, we can calculate Raghu's rank from the last using Statement II as well.

So, either Statement I or II alone are sufficient to answer the question.
