यदि \(A=\{0,1,2,4\}\) और \(B=\{1,2,3,4\}\) हैं, तो \(A\times B\) में कितने युग्म ((x,y)) ऐसे हैं कि (x+y=5)?
If \(A=\{0,1,2,4\}\) and \(B=\{1,2,3,4\}\), how many pairs ((x,y)) in \(A\times B\) satisfy (x+y=5)?
Explanation opens after your attempt
C. (3)
Concept
The valid pairs are ((1,4),(2,3),(4,1)). Always check membership of both components in each pair.
Why this answer is correct
The correct answer is C. (3). The valid pairs are ((1,4),(2,3),(4,1)). Always check membership of both components in each pair.
Exam Tip
सही युग्म ((1,4),(2,3),(4,1)) हैं। हर युग्म में दोनों घटकों की सदस्यता जरूर जांचें।
