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
A. \(R \cap S\) हमेशा संक्रामी होता है\(R \cap S\) is always transitive
Concept
If ((a,b)) and ((b,c)) are in \(R \cap S\), they are in both (R) and (S).
Why this answer is correct
Since both relations are transitive, ((a,c)) is in both.
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।
