Question
Statements: Some bricks are hotels. All bananas
are bricks. No apple is a brick. Some copies are bricks. Conclusions: I. Some hotels are apples. II. Some hotels are not apples. III. Some bananas are not apples. IV. Some apples are not copies. In each of the questions below are given four statements followed by four conclusions numbered I, II and III and IV. You have to take the given statements to be true even if they seem to be at variance with commonly known facts. Read all the conclusions and then decide which of given conclusions logically follows from the given statements disregarding commonly known facts.Solution
No apple is a brick (E) + some bricks are hotels (I) = Some hotels are not apples (O*). Hence, Conclusion I will not follow but conclusion II will follow. All bananas are bricks (A) + No brick is an apple (E) = No banana is an apple (E)`=>` I.I`=>` Some bananas are not apples (O).Hence, Conclusion III will follow. No apple is a brick (E) + Some bricks are copies (I) = Some copies are not apples (O*). Hence, Conclusion IV will not follow.
