क्षेत्र \(x+y\le 5\), \(x+2y\ge 4\), \(x\ge 0\), \(y\ge 0\) में कौन-सा बिंदु अंदर है लेकिन सीमा पर नहीं है?
Which point is inside the region \(x+y\le 5\), \(x+2y\ge 4\), \(x\ge 0\), \(y\ge 0\), but not on the boundary?
Explanation opens after your attempt
Correct Answer
B. ((2,2))
Concept
At ((2,2)), (4<5) and (6>4), so it is inside and not on a boundary. An interior point does not satisfy any boundary as equality.
Why this answer is correct
The correct answer is B. ((2,2)). At ((2,2)), (4<5) and (6>4), so it is inside and not on a boundary. An interior point does not satisfy any boundary as equality.
Exam Tip
((2,2)) पर (4<5) और (6>4), इसलिए यह अंदर है और सीमा पर नहीं। अंदरूनी बिंदु में कोई भी सीमा बराबरी नहीं देती।
