यदि \(A=\{1,2,3,4,5\}\) और \(R=\{(a,b):a+b=6\}\), तो (R) कैसा है?
If \(A=\{1,2,3,4,5\}\) and \(R=\{(a,b):a+b=6\}\), what type is (R)?
Explanation opens after your attempt
B. सममितSymmetric
Concept
If (a+b=6), then (b+a=6) also. Commutativity of addition gives symmetry.
Why this answer is correct
The correct answer is B. सममित / Symmetric. If (a+b=6), then (b+a=6) also. Commutativity of addition gives symmetry.
Exam Tip
यदि (a+b=6) है तो (b+a=6) भी है। जोड़ की क्रमविनिमेयता से सममितता मिलती है।
