यदि \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\) और \(C=\{4,6,8\}\) हैं, तो (A\times\(B\cap C\)) में कितने अवयव होंगे?
If \(A=\{1,2,3,4\}\), \(B=\{2,4,6\}\) and \(C=\{4,6,8\}\), how many elements are in (A\times\(B\cap C\))?
Explanation opens after your attempt
A. (8)
Concept
\(B\cap C={4,6}\), so (n(A\times\(B\cap C\))=4\times2=8). First find the intersection and then multiply.
Why this answer is correct
The correct answer is A. (8). \(B\cap C={4,6}\), so (n(A\times\(B\cap C\))=4\times2=8). First find the intersection and then multiply.
Exam Tip
\(B\cap C={4,6}\), इसलिए (n(A\times\(B\cap C\))=4\times2=8)। पहले प्रतिच्छेद निकालें फिर गुणन करें।
