हल-क्षेत्र \(x+y\geq 6\), \(2x+y\geq 7\), \(0\leq x\leq 4\), \(y\geq 0\) में (y) का न्यूनतम मान क्या है?
In the solution region \(x+y\geq 6\), \(2x+y\geq 7\), \(0\leq x\leq 4\), and \(y\geq 0\), what is the minimum value of (y)?
Explanation opens after your attempt
Correct Answer
B. (2)
Concept
To minimize (y), take the maximum allowed (x=4). Then \(x+y\geq 6\) gives \(y\geq 2\).
Why this answer is correct
The correct answer is B. (2). To minimize (y), take the maximum allowed (x=4). Then \(x+y\geq 6\) gives \(y\geq 2\).
Exam Tip
(y) को न्यूनतम करने के लिए (x) को अधिकतम (4) लें। तब \(x+y\geq 6\) से \(y\geq 2\) मिलता है।
