यदि (R) और (S) दोनों संक्रामी संबंध हैं, तो \(R \cap S\) के बारे में कौन-सा कथन सही है?

If (R) and (S) are both transitive relations, which statement about \(R \cap S\) is correct?

Explanation opens after your attempt
Correct Answer

A. \(R \cap S\) हमेशा संक्रामी होता है\(R \cap S\) is always transitive

Step 1

Concept

If ((a,b)) and ((b,c)) are in \(R \cap S\), they are in both (R) and (S).

Step 2

Why this answer is correct

Since both relations are transitive, ((a,c)) is in both.

Step 3

Exam Tip

Therefore, ((a,c)) is in \(R \cap S\), so the intersection is transitive. चरण 1: यदि ((a,b)) और ((b,c)) दोनों \(R \cap S\) में हैं, तो वे (R) और (S) दोनों में होंगे। चरण 2: दोनों संक्रामी हैं, इसलिए ((a,c)) भी दोनों में होगा। चरण 3: अतः ((a,c)), \(R \cap S\) में होगा।
