हल-क्षेत्र \(x\geq 0\), \(y\geq 0\), \(x+2y\leq 10\), \(2x+y\leq 12\) में (x-y) का अधिकतम मान क्या है?
In the solution region \(x\geq 0\), \(y\geq 0\), \(x+2y\leq 10\), and \(2x+y\leq 12\), what is the maximum value of (x-y)?
Explanation opens after your attempt
Correct Answer
B. (6)
Concept
Checking the corners gives the largest value (x-y=6) at ((6,0)). A linear expression attains its maximum at a corner.
Why this answer is correct
The correct answer is B. (6). Checking the corners gives the largest value (x-y=6) at ((6,0)). A linear expression attains its maximum at a corner.
Exam Tip
कोनों पर जांचने से ((6,0)) पर (x-y=6) सबसे बड़ा है। रैखिक व्यंजक का अधिकतम कोनों पर मिलता है।
