Question

This question has two statements followed by two conclusions numbered I and Il. You have to take the given statements to be true even if they seem to be at variance from commonly known facts. You have to decide which of the given conclusions logically follow(s) from the given statements.

Statements:

No motor is a yak.

Some yaks are wipes.

Conclusions:

(1) No wipe is a yak.

(Il) Some wipes are yaks.

• A. Both conclusions (1) and (II) follow
• B. Only conclusion (lI) follows
• C. Neither conclusion (I) nor (II) follows
• D. Only conclusion (1) follows

Answer 1

Answer:

B. Only conclusion (lI) follows

Let’s analyze step by step.

Statements:

1. No motor is a yak → (Motor ∩ Yak = 0)

2. Some yaks are wipes → (Yak ∩ Wipe ≠ 0)

   Conclusion I: No wipe is a yak

This says (Wipe ∩ Yak = 0)

But statement 2 clearly says:
Some yaks are wipes

So this is directly contradicted.

Conclusion I is false

Conclusion II: Some wipes are yaks

This is just a rephrasing of statement 2:
Some yaks are wipes = Some wipes are yaks

Conclusion II is true

Final Answer: Only Conclusion II follows
