यदि \(A=\{1,2,3\}\), \(B=\{1,2,3,4\}\) और \(C=\{2,3,5\}\) हैं, तो (|A\times(B-C)|+|\(A\times B\)\cap\(A\times C\)|) क्या है?
If \(A=\{1,2,3\}\), \(B=\{1,2,3,4\}\), and \(C=\{2,3,5\}\), what is (|A\times(B-C)|+|\(A\times B\)\cap\(A\times C\)|)?
Explanation opens after your attempt
Correct Answer
B. (12)
Concept
(B-C={1,4}) gives (6) pairs, and \(B\cap C={2,3}\) gives (6) pairs. The sum is (12).
Why this answer is correct
The correct answer is B. (12). (B-C={1,4}) gives (6) pairs, and \(B\cap C={2,3}\) gives (6) pairs. The sum is (12).
Exam Tip
(B-C={1,4}) से (6) और \(B\cap C={2,3}\) से (6) युग्म मिलते हैं। योग (12) है।
