Question
A statement is given followed by two conclusions
numbered I & II. Assuming the statement to be true, even if they seem to be at variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements .  Statements: In Rachna’s class, 60% of the girls who appeared for the examination, passed. There are 75 girls in her class.  Conclusions: I. In Rachna’s class, 40% of the girls who appeared for the exam, failed. II. 45 girls passed the examination.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).
