यदि \(A={x:x\) (100) से छोटे (25) के धनात्मक गुणज हैं(}) तो (A) के उपसमुच्चयों की संख्या क्या है?
If \(A={x:x\) is a positive multiple of (25) less than (100)(}), how many subsets does (A) have?
Explanation opens after your attempt
C. (8)
Concept
\(A=\{25,50,75\}\) has (3) elements, so it has \(2^3=8\) subsets. The boundary (100) is not included.
Why this answer is correct
The correct answer is C. (8). \(A=\{25,50,75\}\) has (3) elements, so it has \(2^3=8\) subsets. The boundary (100) is not included.
Exam Tip
\(A=\{25,50,75\}\) में (3) अवयव हैं इसलिए \(2^3=8\) उपसमुच्चय होंगे। सीमा में (100) शामिल नहीं है।
