are chairs. No chair is a book. Conclusions: I. Some racks are chairs. II. All tables being racks is a possibility. III. No book is a chair. In each of the questions below are given three statements followed by three conclusions numbered 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 given conclusions logically follows from the given statements disregarding commonly known facts.Solution
Some racks are tables (I) + Some tables are chair (I) ⇒ no conclusion can be drawn. Hence, conclusion I will not follow. Some racks are tables (I) ⇒ conversion ⇒ Some tables are racks (I). [Probable conclusion] ⇒ A. Hence, conclusion II will follow. No chair is a book(E) ⇒ conversion ⇒ No book is a chair(E). Hence, conclusion III will follow.
