यदि \(R=\{(1,1),(1,2),(2,1),(2,2)\}\) है, तो (R) किस set पर universal relation है?
If \(R=\{(1,1),(1,2),(2,1),(2,2)\}\), on which set is (R) the universal relation?
Explanation opens after your attempt
Correct Answer
C. \(A=\{1,2\}\)
Concept
These are exactly all pairs of \({1,2}\times{1,2}\). So the base set is \(A=\{1,2\}\).
Why this answer is correct
The correct answer is C. \(A=\{1,2\}\). These are exactly all pairs of \({1,2}\times{1,2}\). So the base set is \(A=\{1,2\}\).
Exam Tip
ये exactly \({1,2}\times{1,2}\) के सभी pairs हैं। इसलिए base set \(A=\{1,2\}\) है।
