यदि \(A=\{1,2,3,4\}\) और \(B=\{3,4,5,6\}\) है, तो \(\mathcal{P}(A\cup B)|-|\mathcal{P}(A\cap B)\) कितना है?
If \(A=\{1,2,3,4\}\) and \(B=\{3,4,5,6\}\), what is \(\mathcal{P}(A\cup B)|-|\mathcal{P}(A\cap B)\)?

Correct Answer
C. (60)
Concept
\(|A\cup B|=6\) and \(|A\cap B|=2\), so \(2^6-2^2=64-4=60\). In exams, first find the sizes of union and intersection.
Why this answer is correct
The correct answer is C. (60). \(|A\cup B|=6\) and \(|A\cap B|=2\), so \(2^6-2^2=64-4=60\). In exams, first find the sizes of union and intersection.
Exam Tip
\(|A\cup B|=6\) और \(|A\cap B|=2\), इसलिए \(2^6-2^2=64-4=60\)। परीक्षा में पहले union और intersection की size निकालें।
