Correct answer: C. (A), (C) and (D) onlyकेवल (A), (C) और (D)

If the A proposition is true: its contrary E ('No women are honest') is false (A); its contradictory O ('Some women are not honest') is false (C), so (B) is wrong; and its subaltern I ('Some women are honest') is true (D). Hence (A), (C) and (D) only.यदि A तर्कवाक्य सत्य है: इसका विपरीत E ('कोई महिला ईमानदार नहीं है') असत्य है (A); इसका व्याघाती O ('कुछ महिलाएँ ईमानदार नहीं हैं') असत्य है (C), अतः (B) गलत है; और इसका उपाश्रित I ('कुछ महिलाएँ ईमानदार हैं') सत्य है (D)। अतः केवल (A), (C) और (D)।More Logical Reasoning questions
