यदि \(A\subseteq B\), तो \(A\cup B\) और \(A\cap B\) क्रमशः क्या होंगे?
If \(A\subseteq B\), what are \(A\cup B\) and \(A\cap B\), respectively?
Explanation opens after your attempt
Correct Answer
A. (B) और (A)(B) and (A)
Concept
When \(A\subseteq B\), the union is (B) and the common part is (A). This is immediate from the subset Venn diagram.
Why this answer is correct
The correct answer is A. (B) और (A) / (B) and (A). When \(A\subseteq B\), the union is (B) and the common part is (A). This is immediate from the subset Venn diagram.
Exam Tip
जब \(A\subseteq B\), तब मिलाकर (B) और साझा भाग (A) होता है। उपसमुच्चय वाले वेन आरेख में यह तुरंत दिखता है।
