In the question two statements are given, followed by three conclusions, I, II and III. You have to consider the statements to be true even if it seems to be at variance from commonly known facts. You have to decide which of the given conclusions, if any, supports the given statements.
Statement 1: All the students in a class are bright.
Statement 2: X is NOT bright.
Conclusion I: Some students are NOT bright.
Conclusion II: X must work hard.
Conclusion III: X is NOT a student of that class.
- AOnly conclusion I follows
- BOnly conclusion II follows
- COnly conclusion III follows
- DNeither of the 3 follow
Solution & Step-by-step Explanation
Statement 1 says all* students in the class are bright. This directly contradicts Conclusion I ("Some students are NOT bright"). So, I does not follow.
* Conclusion II ("X must work hard") is an advice/suggestion, not a logical deduction from the statements.
* Since all students in the class are bright and X is not bright, X cannot belong to that class. Therefore, Conclusion III ("X is NOT a student of that class") definitely follows.
* Conclusion II ("X must work hard") is an advice/suggestion, not a logical deduction from the statements.
* Since all students in the class are bright and X is not bright, X cannot belong to that class. Therefore, Conclusion III ("X is NOT a student of that class") definitely follows.
