यदि \(A=\{1,2,{1,2}\}\), तो कौन सा कथन सही है?
If \(A=\{1,2,{1,2}\}\), which statement is correct?
Explanation opens after your attempt
Correct Answer
A. \({1,2}\in A\) और \({1,2}\in\mathcal{P}(A)\)\({1,2}\in A\) and \({1,2}\in\mathcal{P}(A)\)
Concept
({1,2}) is an element of (A) and also a subset of (A). Hence it belongs to both (A) and (\mathcal{P}(A)).
Why this answer is correct
The correct answer is A. \({1,2}\in A\) और \({1,2}\in\mathcal{P}(A)\) / \({1,2}\in A\) and \({1,2}\in\mathcal{P}(A)\). ({1,2}) is an element of (A) and also a subset of (A). Hence it belongs to both (A) and (\mathcal{P}(A)).
Exam Tip
({1,2}) (A) का एक तत्व है और साथ ही (A) का उपसमुच्चय भी है। इसलिए यह (A) में भी है और (\mathcal{P}(A)) में भी है।
