हल-क्षेत्र \(x\geq 0\), \(y\geq 0\), \(x+y\leq a\) अरिक्त और सीमित होने के लिए (a) की सही शर्त क्या है?
For the region \(x\geq 0\), \(y\geq 0\), \(x+y\leq a\) to be non-empty and bounded, what is the correct condition on (a)?
Explanation opens after your attempt
Correct Answer
B. \(a\geq 0\)
Concept
If \(a\geq 0\), at least ((0,0)) is in the solution and the region remains bounded. If (a<0), there is no solution in the first quadrant.
Why this answer is correct
The correct answer is B. \(a\geq 0\). If \(a\geq 0\), at least ((0,0)) is in the solution and the region remains bounded. If (a<0), there is no solution in the first quadrant.
Exam Tip
यदि \(a\geq 0\) है तो कम से कम ((0,0)) हल में आता है और क्षेत्र सीमित रहता है। (a<0) होने पर प्रथम चतुर्थांश में कोई हल नहीं मिलेगा।
