असमानताओं \(2x+y\leq 9\), \(x+y\leq 7\), \(x\geq 1\), \(y\geq 0\) के हल-क्षेत्र में (y) का अधिकतम मान क्या है?
In the solution region of \(2x+y\leq 9\), \(x+y\leq 7\), \(x\geq 1\), and \(y\geq 0\), what is the maximum value of (y)?
Explanation opens after your attempt
A. (6)
Concept
To maximize (y), take the minimum allowed (x=1). Then \(2+y\leq 9\) and \(1+y\leq 7\) give \(y\leq 6\).
Why this answer is correct
The correct answer is A. (6). To maximize (y), take the minimum allowed (x=1). Then \(2+y\leq 9\) and \(1+y\leq 7\) give \(y\leq 6\).
Exam Tip
(y) को अधिकतम करने के लिए (x) का न्यूनतम मान (1) लें। तब \(2+y\leq 9\) और \(1+y\leq 7\) से \(y\leq 6\) मिलता है।
