क्षेत्र \(x+y\le 10\), \(x+3y\le 18\), \(x\ge 0\), \(y\ge 0\) में (y) का अधिकतम मान क्या है?
What is the maximum value of (y) in the region \(x+y\le 10\), \(x+3y\le 18\), \(x\ge 0\), \(y\ge 0\)?
Explanation opens after your attempt
B. (6)
Concept
At (x=0), the conditions give \(y\le 10\) and \(3y\le 18\), so the maximum is (y=6). To maximize a variable, look for the tightest bound in that direction.
Why this answer is correct
The correct answer is B. (6). At (x=0), the conditions give \(y\le 10\) and \(3y\le 18\), so the maximum is (y=6). To maximize a variable, look for the tightest bound in that direction.
Exam Tip
(x=0) पर शर्तें \(y\le 10\) और \(3y\le 18\) देती हैं, इसलिए अधिकतम (y=6)। किसी चर का अधिकतम पाने के लिए उस दिशा की कठोर सीमा देखें।
