यदि किसी समुच्चय के कुल उपसमुच्चय (32) हैं तो उस समुच्चय के उचित उपसमुच्चय कितने होंगे?
If a set has (32) total subsets then how many proper subsets will it have?
Explanation opens after your attempt
Correct Answer
B. (31)
Concept
Total subsets are \(2^n=32\) so proper subsets are (32-1=31). In exams do not count the original set as a proper subset.
Why this answer is correct
The correct answer is B. (31). Total subsets are \(2^n=32\) so proper subsets are (32-1=31). In exams do not count the original set as a proper subset.
Exam Tip
कुल उपसमुच्चय \(2^n=32\) हैं इसलिए उचित उपसमुच्चय (32-1=31) होंगे। परीक्षा में मूल समुच्चय को उचित उपसमुच्चय में न गिनें।
