यदि (A) में (4) अवयव हैं तो (A) पर स्वतुल्य संबंधों की संख्या कितनी होगी?
If (A) has (4) elements, how many reflexive relations are possible on (A)?
Explanation opens after your attempt
A. \(2^{12}\)
Concept
A reflexive relation must contain (4) diagonal pairs. The remaining (16-4=12) pairs are optional, so the count is \(2^{12}\).
Why this answer is correct
The correct answer is A. \(2^{12}\). A reflexive relation must contain (4) diagonal pairs. The remaining (16-4=12) pairs are optional, so the count is \(2^{12}\).
Exam Tip
स्वतुल्य संबंध में (4) विकर्ण युग्म अनिवार्य हैं। शेष (16-4=12) युग्म स्वतंत्र हैं, इसलिए संख्या \(2^{12}\) है।
