यदि \(A=\{1,2,3,4\}\) और संबंध \(R=\{(a,b):a,b\in A,\ a+2=b\}\) है, तो (R) का प्रांत क्या है?
If \(A=\{1,2,3,4\}\) and the relation is \(R=\{(a,b):a,b\in A,\ a+2=b\}\), what is the domain of (R)?
Explanation opens after your attempt
Correct Answer
A. ({1,2})
Concept
The condition (a+2=b) gives the ordered pairs ((1,3)) and ((2,4)). Therefore the domain is ({1,2}).
Why this answer is correct
The correct answer is A. ({1,2}). The condition (a+2=b) gives the ordered pairs ((1,3)) and ((2,4)). Therefore the domain is ({1,2}).
Exam Tip
शर्त (a+2=b) से ordered pairs ((1,3)) और ((2,4)) मिलते हैं। इसलिए प्रांत ({1,2}) है।
