यदि \(A=\{1,2,3,4\}\) और \(B=\{1,2,3,4\}\) हैं, तो \(A\times B\) में कितने युग्म ((a,b)) ऐसे हैं जिनमें (ab>8) है?
If \(A=\{1,2,3,4\}\) and \(B=\{1,2,3,4\}\), how many pairs ((a,b)) in \(A\times B\) satisfy (ab>8)?
Explanation opens after your attempt
B. (3)
Concept
The satisfying pairs are ((3,3),(3,4),(4,3),(4,4)), totaling (4). The correct option should be (C).
Why this answer is correct
The correct answer is B. (3). The satisfying pairs are ((3,3),(3,4),(4,3),(4,4)), totaling (4). The correct option should be (C).
Exam Tip
संतुष्ट युग्म ((3,3),(3,4),(4,3),(4,4)) नहीं बल्कि ((3,3),(3,4),(4,3),(4,4)) कुल (4) हैं। सही विकल्प (C) होना चाहिए।
