यदि (A\triangle B=\(A\setminus B\)\cup\(B\setminus A\)), \(|A\triangle B|=34\) और \(|A\cup B|=51\), तो \(|A\cap B|\) कितना है?
If (A\triangle B=\(A\setminus B\)\cup\(B\setminus A\)), \(|A\triangle B|=34\) and \(|A\cup B|=51\), what is \(|A\cap B|\)?
Explanation opens after your attempt
Correct Answer
A. (17)
Concept
The union is made of the symmetric difference and the common part, so \(|A\cap B|=51-34=17\). Keep Venn regions separate.
Why this answer is correct
The correct answer is A. (17). The union is made of the symmetric difference and the common part, so \(|A\cap B|=51-34=17\). Keep Venn regions separate.
Exam Tip
संघ सममित अंतर और सामान्य भाग से बनता है, इसलिए \(|A\cap B|=51-34=17\)। वेन आरेख में क्षेत्रों को अलग रखें।
