यदि (n(U)=130) और (n\(A\cap B\)=46) है, तो (n(\(A\cap B\)^c)) कितना होगा?

If (n(U)=130) and (n\(A\cap B\)=46), what is (n(\(A\cap B\)^c))?

Explanation opens after your attempt
Correct Answer

B. (84)

Step 1

Concept

The complement is found by subtracting from (U), so (130-46=84). Here the complement of only the common part is asked.

Step 2

Why this answer is correct

The correct answer is B. (84). The complement is found by subtracting from (U), so (130-46=84). Here the complement of only the common part is asked.

Step 3

Exam Tip

पूरक (U) से घटाकर मिलता है, इसलिए (130-46=84)। यहां केवल साझा भाग का पूरक पूछा गया है।
