यदि \(U=\{a,b,c,d,e,f,g,h\}\), (A'={b,d,f,h}) और \(B=\{a,b,c,d\}\), तो \(A\cap B'\) क्या है?
If \(U=\{a,b,c,d,e,f,g,h\}\), (A'={b,d,f,h}) and \(B=\{a,b,c,d\}\), what is \(A\cap B'\)?
Explanation opens after your attempt
A. \({e,g})
Concept
(A=U-A'={a,c,e,g}) and (B'={e,f,g,h}), so \(A\cap B'={e,g}\). First recover the original set from its complement.
Why this answer is correct
The correct answer is A. \({e,g}). (A=U-A'={a,c,e,g}) and (B'={e,f,g,h}), so \(A\cap B'={e,g}\). First recover the original set from its complement.
Exam Tip
(A=U-A'={a,c,e,g}) और (B'={e,f,g,h}), इसलिए \(A\cap B'={e,g}\)। दिए गए पूरक से पहले मूल समुच्चय निकालें।
