यदि किसी समुच्चय (B) के कुल उपसमुच्चय (1024) हैं, तो उसके उचित उपसमुच्चयों की संख्या कितनी होगी?
If a set (B) has (1024) total subsets, how many proper subsets does it have?
Explanation opens after your attempt
A. (1023)
Concept
A proper subset does not include the whole set itself. Therefore the number is (1024-1=1023).
Why this answer is correct
The correct answer is A. (1023). A proper subset does not include the whole set itself. Therefore the number is (1024-1=1023).
Exam Tip
उचित उपसमुच्चय में पूरा समुच्चय स्वयं शामिल नहीं होता। इसलिए संख्या (1024-1=1023) है।
