Question
Two statements are given, followed by two conclusions
numbered I and II. Assuming the statements to be true, even if they seem to be at a variance with commonly known facts, decide which of the conclusions logically follow(s) from the statements. Statements: All Parameter are Standard. Some Standard are Status. Conclusions: I. Some Status are not Standard. II. Some Standard are Parameter.Solution
Some Standard are Status (I) β Conversion β Some Status are not Standard (I). Hence conclusion I does not follow. All Parameter are Standard (A) β Conversion β Some Standard are Parameter (I). Hence conclusion II follows.
