यदि \(A=\{a,b,c,e\}\), \(B=\{b,d,e\}\) और \(C=\{e,f\}\) हैं, तो (\(A\cup B\)\cap \(B\cup C\)) क्या है?
If \(A=\{a,b,c,e\}\), \(B=\{b,d,e\}\), and \(C=\{e,f\}\), what is (\(A\cup B\)\cap \(B\cup C\))?
Explanation opens after your attempt
Correct Answer
A. ( {b,d,e} )
Concept
\(A\cup B={a,b,c,d,e}\) and \(B\cup C={b,d,e,f}\); their intersection is ({b,d,e}). Find both unions separately.
Why this answer is correct
The correct answer is A. ( {b,d,e} ). \(A\cup B={a,b,c,d,e}\) and \(B\cup C={b,d,e,f}\); their intersection is ({b,d,e}). Find both unions separately.
Exam Tip
\(A\cup B={a,b,c,d,e}\) और \(B\cup C={b,d,e,f}\), इनका प्रतिच्छेद ({b,d,e}) है। दोनों संघ अलग-अलग निकालें।
