यदि \(A={x:x\in \mathbb{N}, x^2-4x+3=0}\) और \(B=\{1\}\) हैं तो संबंध क्या है?

If \(A={x:x\in \mathbb{N}, x^2-4x+3=0}\) and \(B=\{1\}\) then what is the relation?

Explanation opens after your attempt
Correct Answer

A. \(B\subset A\) और \(B\neq A\)\(B\subset A\) and \(B\neq A\)

Step 1

Concept

The equation has solutions (1) and (3), so \(A=\{1,3\}\). \(B=\{1\}\) is a proper subset of it.

Step 2

Why this answer is correct

The correct answer is A. \(B\subset A\) और \(B\neq A\) / \(B\subset A\) and \(B\neq A\). The equation has solutions (1) and (3), so \(A=\{1,3\}\). \(B=\{1\}\) is a proper subset of it.

Step 3

Exam Tip

समीकरण के हल (1) और (3) हैं, इसलिए \(A=\{1,3\}\) है। \(B=\{1\}\) इसका उचित उपसमुच्चय है।
