यदि \(U={x:x\in \mathbb{N}, x\le 24}\), (A) (2) के गुणजों का समुच्चय है और (B) (3) के गुणजों का समुच्चय है, तो (|\(A\cap B\)'|) क्या होगा?
If \(U={x:x\in \mathbb{N}, x\le 24}\), (A) is the set of multiples of (2) and (B) is the set of multiples of (3), what is (|\(A\cap B\)'|)?
Explanation opens after your attempt
Correct Answer
C. (20)
Concept
\(A\cap B\) contains the multiples of (6): (6,12,18,24), so it has (4) elements. The complement has (24-4=20) elements.
Why this answer is correct
The correct answer is C. (20). \(A\cap B\) contains the multiples of (6): (6,12,18,24), so it has (4) elements. The complement has (24-4=20) elements.
Exam Tip
\(A\cap B\) में (6) के गुणज (6,12,18,24) हैं, इसलिए इसमें (4) तत्व हैं। पूरक में (24-4=20) तत्व होंगे।
