यदि \(U={x:x \in \mathbb{N},x\le 48}\), \(A={x:x \in U,4\mid x}\) और \(B={x:x \in U,6\mid x}\) हैं, तो (n(\(A\cup B\)')) क्या है?
If \(U={x:x \in \mathbb{N},x\le 48}\), \(A={x:x \in U,4\mid x}\), and \(B={x:x \in U,6\mid x}\), what is (n(\(A\cup B\)'))?
Explanation opens after your attempt
A. (32)
Concept
Numbers divisible by (4) or (6) are (12+8-4=16). So the complement has (48-16=32) elements.
Why this answer is correct
The correct answer is A. (32). Numbers divisible by (4) or (6) are (12+8-4=16). So the complement has (48-16=32) elements.
Exam Tip
(4) या (6) से विभाज्य संख्याएं (12+8-4=16) हैं। इसलिए पूरक में (48-16=32) सदस्य होंगे।
