यदि \(U=\{1,2,3,4\}\), \(A=\{1,4\}\) और (B=A') है तो (B) क्या है?
If \(U=\{1,2,3,4\}\), \(A=\{1,4\}\) and (B=A'), what is (B)?
Explanation opens after your attempt
Correct Answer
B. ({2,3})
Concept
(A') contains the elements left after removing (1) and (4) from (U). Hence \(B=\{2,3\}\).
Why this answer is correct
The correct answer is B. ({2,3}). (A') contains the elements left after removing (1) and (4) from (U). Hence \(B=\{2,3\}\).
Exam Tip
(A') में (U) से (1) और (4) हटाने पर बचे तत्व आते हैं। इसलिए \(B=\{2,3\}\) है।
