Hint:

In data sufficiency questions, focus on the statement that directly addresses the question and provides sufficient data. In this case, Keshav's tuition is directly related to his success.

Answer 1

The Correct Option is B

Step 1: Understanding the question.
The question asks why Keshav has done well in his class 8th exam. We need to determine the reason for his success.
Step 2: Analyzing the statements.
(I) There were only a few good students in his class: This statement does not directly explain why Keshav did well. It only provides information about the class, not about Keshav's performance.
(II) Keshav took tuition for all the subjects: This statement directly addresses the reason for Keshav's good performance, as tuition for all subjects likely helped him improve his academic performance.
Step 3: Conclusion.
The correct answer is (B) If only statement II is required to answer the question, as taking tuition is the key factor in explaining Keshav's success.
