Question
In the question below some statements are given
followed by three conclusions I, II and III. 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 conclusion definitely follows from the given statements, disregarding commonly known facts. Statements: Some Table are Chair. No Chair is Door. Some Door are Handle. Conclusions: I. Some Table are not Handle. II. Some Handle are not Chair. III. No Table is Door.Solution
Some Table are Chair (I) + No Chair is Door (E) β Some Table are not Door (O) + Some Door are Handle. (I) β No conclusion. Hence neither conclusion I nor III follow. No Chair is Door (E) + Some Door are Handle (I) β Some Handle are not Chair (O*). Hence conclusion II follows.
