\(A=\{1,2,3,4,5\}\) पर \(R=\{(a,b):a+b=2a\}\) है। (R) किस पहचान से सरल होगा?
On \(A=\{1,2,3,4,5\}\), \(R=\{(a,b):a+b=2a\}\). Which identity does (R) simplify to?
Explanation opens after your attempt
A. (a=b)
Concept
\(a+b=2a\Rightarrow b=a\), so it becomes the identity relation. Simplify the equation to identify the relation.
Why this answer is correct
The correct answer is A. (a=b). \(a+b=2a\Rightarrow b=a\), so it becomes the identity relation. Simplify the equation to identify the relation.
Exam Tip
\(a+b=2a\Rightarrow b=a\), इसलिए यह पहचान संबंध बनता है। समीकरण को सरल करके relation पहचानें।
