Show answer & explanation
Correct answer: D. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
Explanation
If A is true, its subaltern I is true → (III). If E is true, I (its contradictory) is false → (IV). If I is true, A and O are undetermined, so 'O is undetermined' → (I). If O is true, E and I are undetermined, so 'I is undetermined' → (II). Hence (A)-(III), (B)-(IV), (C)-(I), (D)-(II).यदि A सत्य है तो उसका अधीन (subaltern) I सत्य होगा → (III)। यदि E सत्य है तो उसका विरोधाभासी I असत्य होगा → (IV)। यदि I सत्य है तो A और O अनिश्चित रहते हैं, अतः 'O अनिश्चित है' → (I)। यदि O सत्य है तो E और I अनिश्चित रहते हैं, अतः 'I अनिश्चित है' → (II)। इस प्रकार (A)-(III), (B)-(IV), (C)-(I), (D)-(II)।More Logical Reasoning questions
