यदि \(A=\{1,2,4\}\) और \(B=\{1,3\}\) हैं, तो \(A\times B\) में पहला घटक दूसरे घटक से बड़ा होने वाले कितने युग्म हैं?
If \(A=\{1,2,4\}\) and \(B=\{1,3\}\), how many pairs in \(A\times B\) have first component greater than second component?
Explanation opens after your attempt
C. (3)
Concept
The pairs are ((2,1),(4,1),(4,3)). During comparison, do not reverse the first and second positions of \(A\times B\).
Why this answer is correct
The correct answer is C. (3). The pairs are ((2,1),(4,1),(4,3)). During comparison, do not reverse the first and second positions of \(A\times B\).
Exam Tip
ऐसे युग्म ((2,1),(4,1),(4,3)) हैं। तुलना करते समय \(A\times B\) का पहला और दूसरा स्थान न बदलें।
