In the following question, some statements are given followed by conclusions.
In the following question, some statements are given followed by conclusions. Taking the statements to be true even if they seem to be at variance from commonly known facts, decide which conclusion logically follows.
निम्नलिखित प्रश्न में कुछ कथन दिए गए हैं, जिनके बाद निष्कर्ष दिए गए हैं। कथनों को सत्य मानते हुए,
Statements / कथन:
I. All R are P.
सभी R, P हैं।
II. All P are J.
सभी P, J हैं।
Conclusions / निष्कर्ष:
I. All P are R.
सभी P, R हैं।
II. All J are P.
सभी J, P हैं।
III. All R are J.
सभी R, J हैं।
भले ही वे सामान्य तथ्यों से भिन्न प्रतीत हों, बताइए कि कौन-सा निष्कर्ष तार्किक रूप से सही है।
Detailed Solution & Logic
Only conclusion III follows केवल निष्कर्ष III अनुसरण करता है।
From the statements:
- All R are P. (R ⊆ P)
- All P are J. (P ⊆ J)
Therefore, All R are J (R ⊆ J) definitely follows.
- Conclusion I: "All P are R" does not follow because only R being a subset of P is given, not the reverse.
- Conclusion II: "All J are P" also does not follow because P is a subset of J, but J being a subset of P is not stated.
- Conclusion III: "All R are J" follows logically.
कथनों के अनुसार:
- सभी R, P हैं। (R ⊆ P)
- सभी P, J हैं। (P ⊆ J)
अतः निश्चित रूप से सभी R, J होंगे (R ⊆ J)।
- निष्कर्ष I "सभी P, R हैं" गलत है क्योंकि केवल R का P में शामिल होना बताया गया है।
- निष्कर्ष II "सभी J, P हैं" भी गलत है क्योंकि J का P में शामिल होना सिद्ध नहीं होता।
- निष्कर्ष III "सभी R, J हैं" सही है।
Hence, the correct answer is D) Only conclusion III follows.
अतः सही उत्तर D) केवल निष्कर्ष III अनुसरण करता है।
