\(यदि (A={x:x\) is a vowel in English\(}) और (B={a,e,i}) हैं, तो (B\subseteq A) के आधार पर (A\cup B) क्या है\)?
\(If (A={x:x\) is a vowel in English\(}) and (B={a,e,i}), then using (B\subseteq A), what is (A\cup B)\)?
Explanation opens after your attempt
Correct Answer
A. ( {a,e,i,o,u} )
Concept
\(A=\{a,e,i,o,u\}\) and \(B\subseteq A\), so \(A\cup B=A\). The larger set already includes the smaller set's elements.
Why this answer is correct
The correct answer is A. ( {a,e,i,o,u} ). \(A=\{a,e,i,o,u\}\) and \(B\subseteq A\), so \(A\cup B=A\). The larger set already includes the smaller set's elements.
Exam Tip
\(A=\{a,e,i,o,u\}\) और \(B\subseteq A\) है, इसलिए \(A\cup B=A\) है। बड़े समुच्चय में छोटे के अवयव पहले से शामिल होते हैं।
