यदि \(x\in\mathbb{Z}\) और \(1\le\frac{5x-2}{3}<8\), तो (x) के कितने मान हैं?
If \(x\in\mathbb{Z}\) and \(1\le\frac{5x-2}{3}<8\), how many values of (x) are there?
Explanation opens after your attempt
B. (5)
Concept
This gives \(3\le5x-2<24\), i.e. \(5\le5x<26\). Hence \(1\le x<\frac{26}{5}\), so (x=1,2,3,4,5).
Why this answer is correct
The correct answer is B. (5). This gives \(3\le5x-2<24\), i.e. \(5\le5x<26\). Hence \(1\le x<\frac{26}{5}\), so (x=1,2,3,4,5).
Exam Tip
इससे \(3\le5x-2<24\), यानी \(5\le5x<26\) मिलता है। इसलिए \(1\le x<\frac{26}{5}\), अतः (x=1,2,3,4,5)।
