\(A=\{1,2,3,4,5\}\) 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
Correct Answer

A. (a=b)

Step 1

Concept

\(a+b=2a\Rightarrow b=a\), so it becomes the identity relation. Simplify the equation to identify the relation.

Step 2

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.

Step 3

Exam Tip

\(a+b=2a\Rightarrow b=a\), इसलिए यह पहचान संबंध बनता है। समीकरण को सरल करके relation पहचानें।
