Question

How many students are there in a class?
Statements:
I. When arranged in alphabetical order, Dilip's name is the 15th and Vinod's is the 37th.
II. In reverse order, Vinod's name is 3rd.

• A. If only statement I is required to answer the question
• B. If only statement II is required to answer the question
• C. If both I and II are required to answer the question
• D. If either I or II are required to answer the question
• E. If neither I nor II are required to answer the question

Hint:

When solving questions about data, carefully consider whether the provided information in one or more statements is sufficient to conclude the answer.

Answer 1

The Correct Option is C

Step 1: Analyze statement I.
Statement I gives us the positions of Dilip and Vinod in alphabetical order, but it does not tell us how many students there are in total. It only provides two specific positions, which are insufficient on their own.
Step 2: Analyze statement II.
Statement II gives us the position of Vinod in reverse alphabetical order, but this also does not directly tell us how many students are in the class.
Step 3: Combine statements I and II.
By combining both statements, we can infer the total number of students. If Dilip is 15th in the alphabetical order and Vinod is 37th in the alphabetical order, we know that the class has at least 37 students. Statement II provides additional context but doesn’t change the fact that we need both statements to conclude the total number of students.
Step 4: Conclusion.
The correct answer is (C) If both I and II are required to answer the question, as we need both statements to determine the number of students.
