यदि \(U=\{a,b,c,d,e,f\}\), \(A=\{a,c,e\}\) और \(B=\{b,c,f\}\), तो \(A' \cap B'\) क्या है?
If \(U=\{a,b,c,d,e,f\}\), \(A=\{a,c,e\}\), and \(B=\{b,c,f\}\), what is \(A' \cap B'\)?
Explanation opens after your attempt
Correct Answer
A. ({d})
Concept
Here (A'={b,d,f}) and (B'={a,d,e}). Their intersection is only ({d}).
Why this answer is correct
The correct answer is A. ({d}). Here (A'={b,d,f}) and (B'={a,d,e}). Their intersection is only ({d}).
Exam Tip
(A'={b,d,f}) और (B'={a,d,e}) हैं। उनका प्रतिच्छेद केवल ({d}) है।
