यदि \(x\in\mathbb{Z}\) और (2x+1<8), तो संख्या रेखा पर सबसे बड़ा marked integer कौन-सा होगा?
If \(x\in\mathbb{Z}\) and (2x+1<8), what is the greatest marked integer on the number line?
Explanation opens after your attempt
Correct Answer
B. (3)
Concept
(2x<7) gives \(x<\frac{7}{2}\), so the greatest integer is (3). In exams, choose the integer just before the boundary.
Why this answer is correct
The correct answer is B. (3). (2x<7) gives \(x<\frac{7}{2}\), so the greatest integer is (3). In exams, choose the integer just before the boundary.
Exam Tip
(2x<7) से \(x<\frac{7}{2}\), इसलिए सबसे बड़ा integer (3) है। परीक्षा में integer answer में boundary से पहले वाला पूर्णांक लें।
