Read all the conclusions and then decide which of the given conclusion definitely follows from the given statements, disregarding commonly known facts.

    Statements: No Pencil is a Sharpener. Only

    a few Sharpeners are Erasers. 98% of Erasers are Pens. 100% Pens are Boxes. Conclusions: I. Some Boxes are Pens is a possibility. II. Some Pens are Erasers is a possibility. III. All Sharpeners being Erasers is not a possibility.

    D Both Conclusions I and II follow Correct Answer Incorrect Answer
    E Both Conclusions I and III follow Correct Answer Incorrect Answer

    Solution

    100% Pen are Boxes (A) → Probable conclusion → All Boxes are Pens (A). Hence conclusion I does not follow. 98% of Erasers are Pens (I) → Conversion → Some Pens are Erasers (I). Hence conclusion II does not follow. No Pencil is a Sharpener (E) + Only a few Sharpeners are Erasers (I) → Some Erasers are not Pencils (O) → Probable conclusion → All Sharpeners may be Erasers (A). Hence conclusion III follows.
