Q: Statements: No Tables is Chairs. No Chairs is Desks. Conclusions: I. No Tables is Desks. II. Some Tables are Desks.

Q: Statements: Some Apples are not Mangoes. All Bananas are Mangoes. Conclusions: I. Some Apples are not Bananas. II. Some Mangoes are Bananas.

Correct Answer: Option C (Both conclusions I and II follow). Since all Bananas are Mangoes, the Apples that are not Mangoes definitely cannot be Bananas. Hence some Apples are not Bananas. All Bananas are Mangoes implies some Mangoes are Bananas. Both follow.

Q: Statements: All Shirts are Pants. All Shirts are Shoes. Conclusions: I. Some Pants are Shoes. II. All Pants are Shoes.
