Question
Statements: Some copy are not book. Only a
few book are paper. Only paper are notebook. Conclusions: Some copy may be paper. All paper being book is a possibility. No copy is book is a possibility. In each of the question below are given some statements followed by some 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 copy are not book (O) + Some book are paper (I) → Probable conclusion → Some copy may be paper (I). Hence conclusion I follows. Only a few book are paper → Probable conclusion → All paper may be book (A). Hence conclusion II follows. Some copy are not book (O) → Probable conclusion → No copy may be book (E). Hence conclusion III follows. Alternate Method -
