यदि (B) को (A) का पूरक कहा गया है, तो कौन सा कथन अवश्य सही होगा?
If (B) is called the complement of (A), which statement must be true?
Explanation opens after your attempt
Correct Answer
A. \(A\cap B=\varnothing\) और \(A\cup B=U\)\(A\cap B=\varnothing\) and \(A\cup B=U\)
Concept
A complement set is disjoint from (A), and together they form (U). This is the simplest rule to check complement.
Why this answer is correct
The correct answer is A. \(A\cap B=\varnothing\) और \(A\cup B=U\) / \(A\cap B=\varnothing\) and \(A\cup B=U\). A complement set is disjoint from (A), and together they form (U). This is the simplest rule to check complement.
Exam Tip
पूरक समुच्चय (A) से असंबद्ध होता है और दोनों मिलकर (U) बनाते हैं। यही पूरक जांचने का सबसे सरल नियम है।
