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
Correct Answer

A. (32)

Step 1

Concept

Numbers divisible by (4) or (6) are (12+8-4=16). So the complement has (48-16=32) elements.

Step 2

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.

Step 3

Exam Tip

(4) या (6) से विभाज्य संख्याएं (12+8-4=16) हैं। इसलिए पूरक में (48-16=32) सदस्य होंगे।
