कौन सा बिंदु (x+2y=8) सीमा पर है और साथ में \(x-y\leq 1\) को भी संतुष्ट करता है?
Which point lies on the boundary (x+2y=8) and also satisfies \(x-y\leq 1\)?
Explanation opens after your attempt
A. ((2,3))
Concept
At ((2,3)), (x+2y=8) and (x-y=-1). Thus it lies on the boundary and also satisfies the second inequality.
Why this answer is correct
The correct answer is A. ((2,3)). At ((2,3)), (x+2y=8) and (x-y=-1). Thus it lies on the boundary and also satisfies the second inequality.
Exam Tip
((2,3)) पर (x+2y=8) और (x-y=-1) है। इसलिए यह सीमा पर भी है और दूसरी असमानता को भी पूरा करता है।
