Question
Statements: No clerk is an
assistant. Some assistants are officers. Conclusions: I. Some clerks are not officers. II. Some officers are assistants. In each question below are given two statements followed by two conclusions numbered I and II. You have to take the two given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the two given statements, disregarding commonly known facts. Give Answer: Give answer 1) if only conclusion I follows. Give answer 2) if only conclusion II follows. Give answer 3) if either conclusion I or II follows. Give answer 4) if neither conclusion I nor II follows. Give answer 5) if both conclusions I and II follow.Solution
No clerk is an assistant (E) + Some assistants are officers (I) = Some officers are not clerks (O * ). Hence, conclusion I will not follow. Some assistants are officers (I) ⇒ conversion ⇒ Some officers are assistants. Hence, conclusion II will follow.
