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
Correct Answer

A. ({1,2,3,4,5})

Step 1

Concept

The inequality gives \(5x\leq 25\), so \(x\leq 5\). Taking positive integers in \(\mathbb{N}\), the solutions are (1) through (5).

Step 2

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).

Step 3

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।
