यदि \(A=\{1,2,3,4\}\) और \(R=\{(a,b):a>b\}\), तो (R) का परिसर क्या है?
If \(A=\{1,2,3,4\}\) and \(R=\{(a,b):a>b\}\), what is the range of (R)?
Explanation opens after your attempt
Correct Answer
A. ( {1,2,3} )
Concept
The second component must have some greater \(a\in A\), so (1,2,3) appear. There is no element in (A) greater than (4).
Why this answer is correct
The correct answer is A. ( {1,2,3} ). The second component must have some greater \(a\in A\), so (1,2,3) appear. There is no element in (A) greater than (4).
Exam Tip
दूसरा घटक ऐसा होना चाहिए जिससे बड़ा कोई \(a\in A\) मिले, इसलिए (1,2,3) आते हैं। (4) से बड़ा कोई अवयव (A) में नहीं है।
