Statements: (a) All pens are pencils. (b) No pencil is a clip. (c) No pencil is a duster. Conclusions: I. Some dusters are not pens. II. Some pens are not clips. III. All pencils are pens. IV. Some pens are pencils.
- Only I, II and IV follow
- Only IV follows
- All follow
- None follows
Correct answer: Only I, II and IV follow
Solution
From 'All pens are pencils' and 'No pencil is a clip', pens cannot be clips, so some pens are not clips follows. Since pens are pencils and no pencil is a duster, dusters are outside pencils, so some dusters are not pens follows. 'All pencils are pens' is the reverse of the given statement and does not follow.
