Syllogism

Q: Statements: All Pens are Pencils. All Pencils are Erasers. Conclusions: I. All Pens are Erasers. II. Some Pencils are Pens.

Correct Answer: Option C (Both conclusions I and II follow). Since all Pens are inside Pencils and all Pencils are inside Erasers, all Pens are definitely Erasers. Also, since all Pens are Pencils, the intersection implies some Pencils are Pens. Both follow.

Q: Statements: Some Tables are Chairs. All Chairs are Desks. Conclusions: I. Some Tables are Desks. II. All Tables are Desks.

Correct Answer: Option A (Only conclusion I follows). Since some Tables are Chairs and all Chairs are Desks, the overlapping part of Tables must also be Desks. Hence some Tables are Desks. We cannot definitively say all Tables are Desks. Only I follows.

Q: Statements: All Apples are Mangoes. No Mangoes is Bananas. Conclusions: I. No Apples is Bananas. II. Some Mangoes are Apples.

Correct Answer: Option C (Both conclusions I and II follow). Since all Apples are inside Mangoes, and Mangoes has no intersection with Bananas, Apples cannot intersect Bananas. Also, all Apples are Mangoes implies some Mangoes are Apples. Both follow.

Q: Statements: Some Shirts are Pants. No Pants is Shoes. Conclusions: I. Some Shirts are not Shoes. II. No Shirts is Shoes.

Correct Answer: Option A (Only conclusion I follows). The part of Shirts that overlaps with Pants cannot be Shoes. Hence some Shirts are not Shoes. We cannot conclude that no Shirts is Shoes entirely. Only I follows.

Q: Statements: All Doctors are Engineers. Some Engineers are Teachers. Conclusions: I. Some Doctors are Teachers. II. Some Teachers are Engineers.

Correct Answer: Option B (Only conclusion II follows). We know some Engineers are Teachers, which directly implies some Teachers are Engineers. However, the intersection of Engineers and Teachers might not touch Doctors. Hence I does not follow. Only II follows.
