यदि \(A=\{1,2\}\), \(B=\{3,4\}\) और \(R=\{(1,3),(2,4)\}\) है, तो (R) किसका उपसमुच्चय है?
If \(A=\{1,2\}\), \(B=\{3,4\}\) and \(R=\{(1,3),(2,4)\}\), then (R) is a subset of which set?
Explanation opens after your attempt
Correct Answer
A. \(A\times B\)
Concept
In every pair of (R), the first component is from (A) and the second is from (B). Therefore \(R\subseteq A\times B\).
Why this answer is correct
The correct answer is A. \(A\times B\). In every pair of (R), the first component is from (A) and the second is from (B). Therefore \(R\subseteq A\times B\).
Exam Tip
(R) के हर युग्म में पहला घटक (A) से और दूसरा (B) से है। इसलिए \(R\subseteq A\times B\)।
