यदि \(U={1,2,\ldots,12}\) और (A'={1,5,7,11}), तो (A) क्या है?
If \(U={1,2,\ldots,12}\) and (A'={1,5,7,11}), what is (A)?
Explanation opens after your attempt
A. \({2,3,4,6,8,9,10,12})
Concept
(A) contains the elements of (U) that are not in (A'). Therefore \(A=\{2,3,4,6,8,9,10,12\}\).
Why this answer is correct
The correct answer is A. \({2,3,4,6,8,9,10,12}). (A) contains the elements of (U) that are not in (A'). Therefore \(A=\{2,3,4,6,8,9,10,12\}\).
Exam Tip
(A) में (U) के वे अवयव होंगे जो (A') में नहीं हैं। इसलिए \(A=\{2,3,4,6,8,9,10,12\}\) है।
