    C Both conclusions I and II follow Correct Answer Incorrect Answer
    D Neither conclusion follows Correct Answer Incorrect Answer

    Solution

    In Rachna’s class, 40% of the girls who appeared for the exam, failed. à TRUE (Because 60% of the girls who appeared for the exam, passed) 45 girls passed the examination à FALSE (Because we don’t know the total number of students who appeared in the exam) This conclusion cannot be logically inferred from the statement. The statement only provides information about the percentage of girls who appeared in the exam. Therefore, only conclusion I follows. Hence, the correct answer is (A).
