\(यदि (O={x:x\) एक प्राकृतिक संख्या है और x 4 का गुणज है तथा \(x<18}) है, तो (O) क्या है\)?
\(If (O={x:x\) is a natural number and x is a multiple of 4 with \(x<18}), what is (O)\)?
Explanation opens after your attempt
Correct Answer
A. \(O=\{4,8,12,16\}\)
Concept
(4) के गुणज \(4,8,12,16,20,\dots\) हैं। / Multiples of (4) are \(4,8,12,16,20,\dots\).
Why this answer is correct
(18) से छोटे गुणज (4,8,12,16) हैं। / The multiples less than (18) are (4,8,12,16).
Exam Tip
(x<18) के कारण (18) या उससे बड़ी संख्या न लें। / Because (x<18), do not include (18) or any larger number.
