Explanation opens after your attempt
Correct Answer

B. (12)

Step 1

Concept

First (n\(A\cup B\)=100-18=82). Then (n\(A\cap B\)=48+46-82=12).

Step 2

Why this answer is correct

The correct answer is B. (12). First (n\(A\cup B\)=100-18=82). Then (n\(A\cap B\)=48+46-82=12).

Step 3

Exam Tip

पहले (n\(A\cup B\)=100-18=82)। फिर (n\(A\cap B\)=48+46-82=12)।
