हल-क्षेत्र \(x\geq 0\), \(y\geq 0\), \(x+2y\leq 10\), \(3x+y\leq 12\) में (3x+2y) का अधिकतम मान क्या है?

In the solution region \(x\geq 0\), \(y\geq 0\), \(x+2y\leq 10\), and \(3x+y\leq 12\), what is the maximum value of (3x+2y)?

Explanation opens after your attempt
Correct Answer

A. (16)

Step 1

Concept

Checking the corners gives (10) at ((0,5)), (12) at ((4,0)), and (16) at (\left\(\frac{14}{5},\frac{18}{5}\right\)). A linear expression attains its maximum at a corner.

Step 2

Why this answer is correct

The correct answer is A. (16). Checking the corners gives (10) at ((0,5)), (12) at ((4,0)), and (16) at (\left\(\frac{14}{5},\frac{18}{5}\right\)). A linear expression attains its maximum at a corner.

Step 3

Exam Tip

कोनों पर जांचने से ((0,5)) पर (10), ((4,0)) पर (12), और (\left\(\frac{14}{5},\frac{18}{5}\right\)) पर (16) मिलता है। रैखिक व्यंजक का अधिकतम कोनों पर मिलता है।
