Question from UPSC Prelims 2022 CSAT Paper
Explanation :
Conclusion-I: All chairs are books.
Conclusion-III : All books are chairs.
The books that are pen can never be a chair. Hence, Conclusion-I and III are not true.
Conclusion-II : Some chairs are pens.
Statement 2 says No chair is a pen. So Conclusion-II is incorrect.
