यदि \(U=\{1,2,3,4,5\}\) और (A'={4,5}) है तो (A) क्या हो सकता है?
If \(U=\{1,2,3,4,5\}\) and (A'={4,5}), what can (A) be?
Explanation opens after your attempt
A. ({1,2,3})
Concept
If the complement is (4,5), then (A) contains the remaining elements of (U). So \(A=\{1,2,3\}\).
Why this answer is correct
The correct answer is A. ({1,2,3}). If the complement is (4,5), then (A) contains the remaining elements of (U). So \(A=\{1,2,3\}\).
Exam Tip
यदि पूरक (4,5) है तो (A) में (U) के बाकी तत्व होंगे। इसलिए \(A=\{1,2,3\}\) है।
