\(यदि (A={x\in \mathbb{N}:x\) is a factor of \(24}) और (B={1,2,3,4,6,8,12,24}) है, तो कौन सा कथन सही है\)?
\(If (A={x\in \mathbb{N}:x\) is a factor of \(24}) and (B={1,2,3,4,6,8,12,24}), which statement is correct\)?
Explanation opens after your attempt
Correct Answer
A. (A=B)
Concept
The natural factors of (24) are (1,2,3,4,6,8,12,24).
Why this answer is correct
These are exactly the elements of (B).
Exam Tip
Converting set-builder form to roster form helps check equality. चरण 1: (24) के सभी प्राकृतिक गुणनखंड (1,2,3,4,6,8,12,24) हैं। चरण 2: यही सभी अवयव (B) में भी हैं। चरण 3: समुच्चय-निर्माण रूप को सूची रूप में बदलकर बराबरी जाँचना आसान होता है।
