यदि (n(A)=56), (n(B)=61), (n(A-B)=19) और (n(B-A)=24) है, तो (n\(A\cap B\)) कितना होगा?

If (n(A)=56), (n(B)=61), (n(A-B)=19), and (n(B-A)=24), what is (n\(A\cap B\))?

Explanation opens after your attempt
Correct Answer

B. (37)

Step 1

Concept

(n\(A\cap B\)=56-19=37), and (61-24=37) confirms it. The same common part should be obtained from both sides.

Step 2

Why this answer is correct

The correct answer is B. (37). (n\(A\cap B\)=56-19=37), and (61-24=37) confirms it. The same common part should be obtained from both sides.

Step 3

Exam Tip

(n\(A\cap B\)=56-19=37) है और (61-24=37) से पुष्टि होती है। दोनों तरफ से समान साझा भाग मिलना चाहिए।
