यदि \(U={1,2,\ldots,100}\), (A) (4) के गुणजों का समुच्चय है और (B) (6) के गुणजों का समुच्चय है, तो (n(\(A \cap B\)')) कितना है?

If \(U={1,2,\ldots,100}\), (A) is the set of multiples of (4), and (B) is the set of multiples of (6), what is (n(\(A \cap B\)'))?

Explanation opens after your attempt
Correct Answer

A. (92)

Step 1

Concept

\(A \cap B\) contains multiples of (12), and there are (8) up to (100). So the complement has (100-8=92) elements.

Step 2

Why this answer is correct

The correct answer is A. (92). \(A \cap B\) contains multiples of (12), and there are (8) up to (100). So the complement has (100-8=92) elements.

Step 3

Exam Tip

\(A \cap B\) में (12) के गुणज होंगे, जो (100) तक (8) हैं। इसलिए पूरक में (100-8=92) सदस्य हैं।
