यदि \(U=\{1,2,3,4,5,6,7,8,9,10\}\) और \(A={x:x\in U, x\) न तो (2) न (5) से विभाज्य है(}), तो (A') क्या है?
If \(U=\{1,2,3,4,5,6,7,8,9,10\}\) and \(A={x:x\in U, x\) is divisible by neither (2) nor (5)(}), what is (A')?
Explanation opens after your attempt
Correct Answer
A. ({2,4,5,6,8,10})
Concept
(A) contains (1,3,7,9). So the complement is the elements divisible by (2) or (5): ({2,4,5,6,8,10}).
Why this answer is correct
The correct answer is A. ({2,4,5,6,8,10}). (A) contains (1,3,7,9). So the complement is the elements divisible by (2) or (5): ({2,4,5,6,8,10}).
Exam Tip
(A) में (1,3,7,9) हैं। इसलिए पूरक (2) या (5) से विभाज्य तत्व ({2,4,5,6,8,10}) हैं।
