Consider two Statements and a Question:

Statement-1: Priya is 4 ranks below Seema and is 31st from the bottom.

Statement-2: Ena is 2 ranks above Seema and is 37th from the bottom.

Question: What is Seema’s rank from the top in the class of 40 students?

Which one of the following is correct in respect of the Statement and the Question?

The correct answer is Either Statement-I alone or Satetement-2 alone is sufficient to answer the Question.

Let us analyze the problem step-by-step to determine if either statement alone or both statements together are sufficient to find Seema's rank from the top in a class of 40 students.

Total number of students in the class = 40.

Recall the general formula relating a person's rank from the top, rank from the bottom, and total number of students:

$\text{Rank from Top}=\text{Total Students}-\text{Rank from Bottom}+1$

Evaluating Statement-1:

Statement-1 says: "Priya is 4 ranks below Seema and is 31st from the bottom."

Being 4 ranks "below" Seema means Priya's rank from the bottom is 4 places less than Seema's rank from the bottom (i.e., closer to the bottom).

Therefore, Seema's rank from the bottom = Priya's rank from the bottom + 4

Seema's rank from the bottom = 31 + 4 = 35th from the bottom.

Now, using the total student strength of 40, we can calculate Seema's rank from the top:

$\text{Seema’s rank from the top}=40-35+1=6$

Thus, Statement-1 alone is sufficient to answer the question.

Evaluating Statement-2:

Statement-2 says: "Ena is 2 ranks above Seema and is 37th from the bottom."

Being 2 ranks "above" Seema means Ena's rank from the bottom is 2 places higher than Seema's rank from the bottom (i.e., further from the bottom).

Therefore, Seema's rank from the bottom = Ena's rank from the bottom - 2

Seema's rank from the bottom = 37 - 2 = 35th from the bottom.

Now, using the total student strength of 40, we can calculate Seema's rank from the top:

$\text{Seema’s rank from the top}=40-35+1=6$

Thus, Statement-2 alone is also sufficient to answer the question.

Conclusion:

Since each statement independently provides enough information to uniquely determine Seema's rank from the top, Either Statement-I alone or Satetement-2 alone is sufficient to answer the Question.
