Question

Statement:
1. No engineer is a doctor
2. Some doctors are MBAs
Conclusion:
I. Some doctors are not engineers
II. Some MBAs are not engineers

• A. if only conclusion I follows
• B. if only conclusion II follows
• C. if either I or II follows
• D. if neither I nor II follows
• E. if both follow

Hint:

When analyzing conclusions, ensure they follow directly from the statements without introducing assumptions beyond the provided information.

Answer 1

The Correct Option is A

Step 1: Analyze the statements and conclusions.
We are given two statements:
- (1) No engineer is a doctor.
- (2) Some doctors are MBAs.
From statement (1), we know that no engineer can be a doctor, so there are doctors who are not engineers. Statement (2) tells us that some doctors are MBAs, but it does not directly relate to the engineers or non-engineers.
Step 2: Analyze the conclusions.
- Conclusion I: Some doctors are not engineers. This conclusion logically follows because statement (1) tells us that no engineer is a doctor, so some doctors must be non-engineers. Therefore, conclusion I is valid.
- Conclusion II: Some MBAs are not engineers. This conclusion does not necessarily follow. While some doctors are MBAs, we do not have any direct information about MBAs being engineers or not, so we cannot conclude that some MBAs are not engineers based on the given statements.
Step 3: Conclusion.
The correct answer is (A) if only conclusion I follows, as conclusion I is valid, while conclusion II is not.
