यदि \(x\in\mathbb{N}\) और \(5x-4\leq 21\) है तो हल समुच्चय कौन सा है?
If \(x\in\mathbb{N}\) and \(5x-4\leq 21\), what is the solution set?
Explanation opens after your attempt
A. ({1,2,3,4,5})
Concept
The inequality gives \(5x\leq 25\), so \(x\leq 5\). Taking positive integers in \(\mathbb{N}\), the solutions are (1) through (5).
Why this answer is correct
The correct answer is A. ({1,2,3,4,5}). The inequality gives \(5x\leq 25\), so \(x\leq 5\). Taking positive integers in \(\mathbb{N}\), the solutions are (1) through (5).
Exam Tip
असमता से \(5x\leq 25\) और \(x\leq 5\) मिलता है। \(\mathbb{N}\) में धनात्मक पूर्णांक लेकर हल (1) से (5) तक हैं।
