यदि \(A=\{p,q,r\}\) और \(B=\{q,r,s\}\) है, तो (A\cup\(A\cap B\)) क्या है?
If \(A=\{p,q,r\}\) and \(B=\{q,r,s\}\), what is (A\cup\(A\cap B\))?
Explanation opens after your attempt
Correct Answer
A. ( {p,q,r} )
Concept
\(A\cap B={q,r}\), and it is a part of (A), so the union is (A) itself. This is the absorption law.
Why this answer is correct
The correct answer is A. ( {p,q,r} ). \(A\cap B={q,r}\), and it is a part of (A), so the union is (A) itself. This is the absorption law.
Exam Tip
\(A\cap B={q,r}\) है और यह (A) का भाग है, इसलिए संघ (A) ही होगा। यह अवशोषण नियम है।
