यदि \(U=\{1,2,3,4\}\) और (A'={1,4}) है तो (A) क्या है?
If \(U=\{1,2,3,4\}\) and (A'={1,4}), what is (A)?
Explanation opens after your attempt
Correct Answer
B. ({2,3})
Concept
If the complement is (1,4), then (A) contains the remaining elements of (U). So \(A=\{2,3\}\).
Why this answer is correct
The correct answer is B. ({2,3}). If the complement is (1,4), then (A) contains the remaining elements of (U). So \(A=\{2,3\}\).
Exam Tip
यदि पूरक (1,4) है तो (A) में (U) के बाकी तत्व होंगे। इसलिए \(A=\{2,3\}\) है।
