\(समुच्चय (J={x\in \mathbb{N}: x\) संख्या 30 का भाजक है और \(x>5}) क्या है\)?
\(What is (J={x\in \mathbb{N}: x\) is a divisor of 30 and \(x>5})\)?
Correct answer and explanation
A. \(J=\{6,10,15,30\}\)
Concept
(30) के भाजक (1,2,3,5,6,10,15,30) हैं। / The divisors of (30) are (1,2,3,5,6,10,15,30).
Why this answer is correct
(x>5) के कारण (1,2,3,5) हटेंगे और (6,10,15,30) बचेंगे। / Because (x>5), (1,2,3,5) are removed and (6,10,15,30) remain.
Exam Tip
भाजक लिखने के बाद असमानता की शर्त लगाना आसान रहता है। / It is easier to list the divisors first and then apply the inequality condition.
