यदि \(U={1,2,\ldots,50}\), (A) अभाज्य संख्याओं का और (B) (5) के गुणजों का समुच्चय है, तो \(A\cap B\) क्या है?
If \(U={1,2,\ldots,50}\), (A) is the set of prime numbers and (B) is the set of multiples of (5), then what is \(A\cap B\)?
Explanation opens after your attempt
Correct Answer
A. ({5})
Concept
(5) is both prime and a multiple of (5), so the intersection is ({5}). Check both conditions together.
Why this answer is correct
The correct answer is A. ({5}). (5) is both prime and a multiple of (5), so the intersection is ({5}). Check both conditions together.
Exam Tip
(5) अभाज्य भी है और (5) का गुणज भी है, इसलिए प्रतिच्छेद ({5}) है। दोनों शर्तें साथ जाँचें।
