Some eggs are onions.
All onions are blue.

Conclusions:

II. All onions are eggs.

This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
Neither conclusion I nor II follows.

Logical Reasoning Solution: Statements & Conclusions

This solution analyzes the logical validity of two conclusions based on the provided statements.

Statement Analysis

We are given two statements:

  • Statement 1: Some eggs are onions. This indicates an overlap between the set of eggs and the set of onions. Not all eggs are necessarily onions, and not all onions are necessarily eggs.
  • Statement 2: All onions are blue. This means the entire set of onions is contained within the set of blue things.

Conclusion Analysis

Now, let's evaluate each conclusion based on the statements:

Conclusion I: All eggs are blue.

  • From Statement 1, only *some* eggs are related to onions.
  • From Statement 2, those specific onions (which are also eggs) are blue.
  • However, the statement "Some eggs are onions" does not provide information about the eggs that are *not* onions. These eggs might be blue, or they might not be.
  • Therefore, we cannot definitively conclude that all eggs are blue.

Conclusion II: All onions are eggs.

  • Statement 1 states "Some eggs are onions", implying a partial relationship.
  • This does not mean the reverse is true. There could be onions that are not eggs.
  • Therefore, we cannot conclude that all onions are eggs.

Final Verdict

Based on the analysis, neither Conclusion I nor Conclusion II logically and necessarily follows from the given statements.

The correct option is the one stating that neither conclusion follows.
