यदि \(A=\{1,2,3\}\), तो कथन \({1}\in P(A)\) और \({1}\subseteq P(A)\) में कौन सा सही है?
If \(A=\{1,2,3\}\), which is correct between \({1}\in P(A)\) and \({1}\subseteq P(A)\)?
Explanation opens after your attempt
Correct Answer
A. केवल \({1}\in P(A)\) सही हैOnly \({1}\in P(A)\) is correct
Concept
({1}) is a subset of (A), so it is an element of (P(A)). But (1) is not an element of (P(A)), so \({1}\subseteq P(A)\) is false.
Why this answer is correct
The correct answer is A. केवल \({1}\in P(A)\) सही है / Only \({1}\in P(A)\) is correct. ({1}) is a subset of (A), so it is an element of (P(A)). But (1) is not an element of (P(A)), so \({1}\subseteq P(A)\) is false.
Exam Tip
({1}) समुच्चय (A) का उपसमुच्चय है, इसलिए वह (P(A)) का अवयव है। लेकिन (1), (P(A)) का अवयव नहीं है, इसलिए \({1}\subseteq P(A)\) गलत है।
