यदि \(A=\{1,2,3\}\) और \(B=\{1,2,3,4,5\}\) हैं तो (B) के कितने उपसमुच्चय (A) के भी उपसमुच्चय हैं?
If \(A=\{1,2,3\}\) and \(B=\{1,2,3,4,5\}\), how many subsets of (B) are also subsets of (A)?
Explanation opens after your attempt
Correct Answer
C. (8)
Concept
The subsets lying inside (A) are subsets of both, and their number is \(2^3=8\). Decide the common limit using the smaller set.
Why this answer is correct
The correct answer is C. (8). The subsets lying inside (A) are subsets of both, and their number is \(2^3=8\). Decide the common limit using the smaller set.
Exam Tip
जो उपसमुच्चय (A) के अंदर हैं वही दोनों के लिए उपसमुच्चय होंगे और उनकी संख्या \(2^3=8\) है। साझा सीमा को छोटे समुच्चय से तय करें।
