यदि \(A=\{2,3,4,5\}\) और \(B=\{1,2,3\}\) हैं, तो \(A\times B\) में कितने युग्म ((x,y)) ऐसे हैं कि (x-y=2)?

If \(A=\{2,3,4,5\}\) and \(B=\{1,2,3\}\), how many pairs ((x,y)) in \(A\times B\) satisfy (x-y=2)?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

The valid pairs are ((3,1),(4,2),(5,3)). Choosing (y) and finding (x=y+2) is easy.

Step 2

Why this answer is correct

The correct answer is B. (3). The valid pairs are ((3,1),(4,2),(5,3)). Choosing (y) and finding (x=y+2) is easy.

Step 3

Exam Tip

सही युग्म ((3,1),(4,2),(5,3)) हैं। (y) चुनकर (x=y+2) निकालना आसान है।
