यदि \(A=\{1,2,3\}\), \(B=\{2,3,4\}\) और \(C=\{1,3,5\}\) हैं, तो (A\times\(B\cap C\)) में कितने अवयव होंगे?
If \(A=\{1,2,3\}\), \(B=\{2,3,4\}\) and \(C=\{1,3,5\}\), how many elements are in (A\times\(B\cap C\))?
Explanation opens after your attempt
Correct Answer
C. (3)
Concept
\(B\cap C={3}\), so (n(A\times\(B\cap C\))=3\times1=3). Find the intersection first and then multiply.
Why this answer is correct
The correct answer is C. (3). \(B\cap C={3}\), so (n(A\times\(B\cap C\))=3\times1=3). Find the intersection first and then multiply.
Exam Tip
\(B\cap C={3}\), इसलिए (n(A\times\(B\cap C\))=3\times1=3)। पहले प्रतिच्छेद निकालें फिर गुणन करें।
