यदि \(A=\{1,2,3,4,5,6\}\) है तो (A) के कितने उपसमुच्चय केवल सम संख्याओं से बन सकते हैं?
If \(A=\{1,2,3,4,5,6\}\) then how many subsets of (A) can be formed using only even numbers?
Explanation opens after your attempt
Correct Answer
C. (8)
Concept
The even elements are (2,4,6), and all their subsets are \(2^3=8\). In exams "only" means all other elements are excluded.
Why this answer is correct
The correct answer is C. (8). The even elements are (2,4,6), and all their subsets are \(2^3=8\). In exams "only" means all other elements are excluded.
Exam Tip
सम तत्व (2,4,6) हैं और इनके सभी उपसमुच्चय \(2^3=8\) होंगे। परीक्षा में "केवल" का अर्थ है बाकी तत्वों को पूरी तरह हटाना।
