यदि \(U={x:x\in \mathbb{N}, x\leq 12}\) और \(A={x:x\) (3) का गुणज है(}), तो (A') क्या है?
If \(U={x:x\in \mathbb{N}, x\leq 12}\) and \(A={x:x\) is a multiple of (3)(}), what is (A')?
Explanation opens after your attempt
B. ({1,2,4,5,7,8,10,11})
Concept
(U) contains numbers from (1) to (12), and \(A=\{3,6,9,12\}\). Removing these gives (A').
Why this answer is correct
The correct answer is B. ({1,2,4,5,7,8,10,11}). (U) contains numbers from (1) to (12), and \(A=\{3,6,9,12\}\). Removing these gives (A').
Exam Tip
(U) में (1) से (12) तक संख्याएं हैं और \(A=\{3,6,9,12\}\) है। इन्हें हटाने पर (A') मिलता है।
