यदि \(x\in\mathbb{Z}\) और \(-7\le 3x-1<11\), तो (x) के सभी मान कौन से हैं?
If \(x\in\mathbb{Z}\) and \(-7\le 3x-1<11\), which are all values of (x)?
Explanation opens after your attempt
B. \({-2,-1,0,1,2}\)
Concept
The inequality gives \(-6\le3x<12\), hence \(-2\le x<4\). For integers, the correct list is ({-2,-1,0,1,2,3}).
Why this answer is correct
The correct answer is B. \({-2,-1,0,1,2}\). The inequality gives \(-6\le3x<12\), hence \(-2\le x<4\). For integers, the correct list is ({-2,-1,0,1,2,3}).
Exam Tip
असमानता से \(-6\le3x<12\), अतः \(-2\le x<4\) मिलता है। पूर्णांकों में सही सूची ({-2,-1,0,1,2,3}) होगी।
