यदि \(x\in\mathbb{Z}\) और \(1\leq 2x-1<9\) है तो हल समुच्चय कौन सा है?

If \(x\in\mathbb{Z}\) and \(1\leq 2x-1<9\), what is the solution set?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

From \(1\leq 2x-1<9\), we get \(2\leq 2x<10\), hence \(1\leq x<5\). The integer solutions are (1) through (4).

Step 2

Why this answer is correct

The correct answer is A. ({1,2,3,4}). From \(1\leq 2x-1<9\), we get \(2\leq 2x<10\), hence \(1\leq x<5\). The integer solutions are (1) through (4).

Step 3

Exam Tip

\(1\leq 2x-1<9\) से \(2\leq 2x<10\) और \(1\leq x<5\) मिलता है। पूर्णांक हल (1) से (4) तक हैं।
