Question: What is Suman's rank from the top in a class of forty students?

Statements:
I. Suman is 3 ranks below Deepak from the top.
II. Deepak's rank from the bottom is 23.
III. Suman is 3 ranks above Deepak from the bottom.

Correct answer: Option E - Only statement II and either statement I or statement III are sufficient to answer the question.

Explanation:

To determine Suman's rank from the top in a class of forty students, we need to know the positions of both Suman and Deepak from the top or bottom of the class.

Let's analyze each statement one by one:

Statement I: Suman is 3 ranks below Deepak from the top.
This statement provides the relationship between Suman and Deepak from the top, but it does not give us any direct information about Suman's rank. It only tells us that Suman's rank is three ranks lower than Deepak's rank. Therefore, statement I alone is not sufficient to answer the question.

Statement II: Deepak's rank from the bottom is 23.
This statement gives us the position of Deepak from the bottom of the class. Since the total number of students in the class is 40, we can determine Deepak's rank from the top by subtracting his rank from the bottom from the total number of students. Therefore, Deepak's rank from the top would be 40 - 23 = 17. However, this statement does not provide any direct information about Suman's rank. Therefore, statement II alone is not sufficient to answer the question.

Statement III: Suman is 3 ranks above Deepak from the bottom.
This statement provides the relationship between Suman and Deepak from the bottom, but it does not give us any direct information about Suman's rank. It only tells us that Suman's rank is three ranks higher than Deepak's rank from the bottom. Therefore, statement III alone is not sufficient to answer the question.

Combining statements:
If we combine statement II with either statement I or statement III, we can determine Suman's rank from the top.

- If we combine statement II with statement I, we know that Deepak's rank from the top is 17 and Suman is 3 ranks below Deepak. Therefore, Suman's rank from the top would be 17 - 3 = 14.

- If we combine statement II with statement III, we know that Deepak's rank from the top is 17 and Suman is 3 ranks above Deepak from the bottom. Therefore, Suman's rank from the top would be 17 + 3 = 20.

Therefore, statement II and either statement I or statement III together are sufficient to answer the question.

Conclusion: The correct answer is option E - Only statement II and either statement I or statement III are sufficient to answer the question.
