Take the given statements to be true even if they seem to be at variance with commonly known facts. Then decide which of the given conclusions logically follow the given statements.
Statements:
0% chairs are tables.
All computers are chairs.
Some books are tables.
Conclusions:
I. Not a single table is a computer.
II. Some books are not chairs.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Both conclusions I and II follow.
“0% chairs are tables” means no chair is a table. With the other two statements, the three groups can be drawn as below.
I. Not a single table is a computer. Correct. Every computer is a chair, and no chair is a table, so no computer can be a table.
II. Some books are not chairs. Correct. Some books are tables, and no table is a chair, so those books are not chairs. This holds however the rest of the books are drawn.
