कौन सा बिंदु \(4x+y\ge12\), \(x+4y\ge12\), \(x\ge0\), \(y\ge0\) का संयुक्त हल है?
Which point is a common solution of \(4x+y\ge12\), \(x+4y\ge12\), \(x\ge0\), \(y\ge0\)?
Explanation opens after your attempt
A. ( (2,2) )
Concept
At ( (2,2) ), both left sides equal (10), which is less than (12). Therefore this option cannot be correct and true solutions must make both values at least (12).
Why this answer is correct
The correct answer is A. ( (2,2) ). At ( (2,2) ), both left sides equal (10), which is less than (12). Therefore this option cannot be correct and true solutions must make both values at least (12).
Exam Tip
( (2,2) ) पर दोनों असमानताओं में मान (10) आता है, जो (12) से कम है। इसलिए यह विकल्प सही नहीं हो सकता और सही हलों के लिए दोनों मान कम से कम (12) होने चाहिए।
