हल-क्षेत्र \(x\geq 0\), \(y\geq 0\), \(x+3y\leq 12\), \(x+y\geq 4\) में (y) की सीमा क्या है?

What is the range of (y) in the solution region \(x\geq 0\), \(y\geq 0\), \(x+3y\leq 12\), and \(x+y\geq 4\)?

Explanation opens after your attempt
Correct Answer

C. \(0\leq y\leq 4\)

Step 1

Concept

At (y=0), \(4\leq x\leq 12\) is possible, and at (x=0), the maximum is (y=4). Hence \(0\leq y\leq 4\).

Step 2

Why this answer is correct

The correct answer is C. \(0\leq y\leq 4\). At (y=0), \(4\leq x\leq 12\) is possible, and at (x=0), the maximum is (y=4). Hence \(0\leq y\leq 4\).

Step 3

Exam Tip

(y=0) पर \(4\leq x\leq 12\) संभव है और (x=0) पर अधिकतम (y=4) मिलता है। इसलिए \(0\leq y\leq 4\) है।
