Question
Statements: All Books are Flight. Only
a few Flight are Ticket. No Ticket is a Memo. Conclusions: I. Some Flights are not Memos II. Some Books are not Memos In the question below, three statements are given followed by the conclusions. 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 the given conclusions logically follows from the given statements disregarding commonly known facts.Solution
Some Flight are Ticket (I) + No Ticket is a Memo (E) → Some Flight are not Memo (O). Hence conclusion I follows. All Books are Flights (A) + Some Flight are Ticket (I) →  No conclusion. Hence conclusion II does not follow.
