यदि \(A=\{0,1,2\}\) और \(B=\{0,2,4\}\) हैं, तो \(A\times B\) में कितने युग्म ((x,y)) ऐसे हैं कि (x+y=2)?
If \(A=\{0,1,2\}\) and \(B=\{0,2,4\}\), how many pairs ((x,y)) in \(A\times B\) satisfy (x+y=2)?
Explanation opens after your attempt
Correct Answer
A. (2)
Concept
The valid pairs are ((0,2)) and ((2,0)). ((1,1)) will not appear because \(1\notin B\).
Why this answer is correct
The correct answer is A. (2). The valid pairs are ((0,2)) and ((2,0)). ((1,1)) will not appear because \(1\notin B\).
Exam Tip
सही युग्म ((0,2)) और ((2,0)) हैं। ((1,1)) नहीं आएगा क्योंकि \(1\notin B\)।
