यदि \(U=\{नीला,हरा,पीला,गुलाबी\}\) और \(A=\{हरा,गुलाबी\}\) है तो (A') क्या है?
If \(U=\{blue,green,yellow,pink\}\) and \(A=\{green,pink\}\), what is (A')?
Explanation opens after your attempt
B. ({नीला,पीला})({blue,yellow})
Concept
After removing the colors of (A), blue and yellow remain in (U). Hence (A'={blue,yellow}).
Why this answer is correct
The correct answer is B. ({नीला,पीला}) / ({blue,yellow}). After removing the colors of (A), blue and yellow remain in (U). Hence (A'={blue,yellow}).
Exam Tip
(A) के रंग हटाने पर (U) में नीला और पीला बचते हैं। इसलिए (A'={नीला,पीला}) है।
