\(यदि (A={x:x\in \mathbb{N},x\le 12}), (B={x:x\) is even\(,x\le 12}) और (C={x:x\) is a multiple of \(3,x\le 12}) है, तो (n(B\cap C)) कितना है\)?
\(If (A={x:x\in \mathbb{N},x\le 12}), (B={x:x\) is even\(,x\le 12}) and (C={x:x\) is a multiple of \(3,x\le 12}), then what is (n(B\cap C))\)?
Explanation opens after your attempt
Correct Answer
A. (2)
Concept
\(B\cap C\) contains (6) and (12), so the count is (2). For intersection, both conditions must be satisfied together.
Why this answer is correct
The correct answer is A. (2). \(B\cap C\) contains (6) and (12), so the count is (2). For intersection, both conditions must be satisfied together.
Exam Tip
\(B\cap C\) में (6) और (12) हैं, इसलिए संख्या (2) है। प्रतिच्छेद के लिए दोनों शर्तें साथ में पूरी होनी चाहिए।
