Read the following statement carefully and identify conclusions that follows.
Statement: All A are B. No B is C. All C are D.
conclusions:
I. No A is C
II. Some D are not B.
निम्नलिखित कथन को ध्यानपूर्वक पढ़िए और सही निष्कर्ष पहचानिए।
कथन:
सभी A, B हैं। कोई भी B, C नहीं है। सभी C, D हैं।
निष्कर्ष:
I. कोई भी A, C नहीं है।
II. कुछ D, B नहीं हैं।
Detailed Solution & Logic
Only I follows/ केवल I अनुसरण करता है
Let’s re-analyze carefully (important logic point 👇):
Statements:
-
All A are B → A ⊂ B
-
No B is C → B ∩ C = 0
-
All C are D → C ⊂ D
Conclusion I: No A is C
A ⊂ B and B has no overlap with C ⇒ A also cannot overlap with C
✔️ Conclusion I follows
Conclusion II: Some D are not B
We know: C ⊂ D and C has no overlap with B
BUT ❗ we are not given that C exists (no “some C”)
So we cannot निश्चित say that any D exists which is not B.
👉 Therefore, this is not guaranteed
❌ Conclusion II does NOT follow
Final Answer: Only Conclusion I follows
