Explanation

To determine Seema's rank from the top in a class of 40 students, we need to find her rank from the bottom first. Analyze Statement 1: "Priya is 4 ranks below Seema and is 31st from the bottom." If Priya is 31st from the bottom, and Seema is 4 ranks above Priya (since Priya is 4 ranks below Seema), then Seema's rank from the bottom is 31 + 4 = 35th. With Seema's rank from the bottom (35) and the total number of students (40), we can find her rank from the top: Rank from top = Total students - Rank from bottom + 1 = 40 - 35 + 1 = 6th. Thus, Statement 1 alone is sufficient. Analyze Statement 2: "Ena is 2 ranks above Seema and is 37st from the bottom." If Ena is 37th from the bottom, and Seema is 2 ranks below Ena (since Ena is 2 ranks above Seema), then Seema's rank from the bottom is 37 - 2 = 35th. With Seema's rank from the bottom (35) and the total number of students (40), we can find her rank from the top: Rank from top = Total students - Rank from bottom + 1 = 40 - 35 + 1 = 6th. Thus, Statement 2 alone is sufficient. Since both Statement 1 alone and Statement 2 alone independently provide enough information to answer the question, the correct option is C.
Logical Reasoning: Consider two Statements and a Question: Statement 1: Priya is 4 ranks below Seema and is 31st from the bottom. Statement
