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
Correct Answer

A. (1023)

Step 1

Concept

A proper subset does not include the whole set itself. Therefore the number is (1024-1=1023).

Step 2

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).

Step 3

Exam Tip

उचित उपसमुच्चय में पूरा समुच्चय स्वयं शामिल नहीं होता। इसलिए संख्या (1024-1=1023) है।
