\(A=\{1,2,3\}\) पर relation \(R=\{(1,1),(1,2),(2,2),(2,3),(1,3),(3,3)\}\) है। यह relation किस familiar order जैसा है?
On \(A=\{1,2,3\}\), relation \(R=\{(1,1),(1,2),(2,2),(2,3),(1,3),(3,3)\}\) is given. Which familiar order does this relation resemble?
Explanation opens after your attempt
Correct Answer
A. \(a\leq b\)
Concept
The given pairs are exactly those where the first element is less than or equal to the second. Thus it is the usual order \(\leq\) on (A).
Why this answer is correct
The correct answer is A. \(a\leq b\). The given pairs are exactly those where the first element is less than or equal to the second. Thus it is the usual order \(\leq\) on (A).
Exam Tip
दिए गए pairs वही हैं जिनमें पहला अवयव दूसरे से छोटा या बराबर है। इसलिए यह (A) पर usual order \(\leq\) है।
