Question:

The feasible region represented by the constraints: $x + 2y ≥ 100, 2x-y≤ 0,2x + y ≤ 200, x ≥0, y ≥ 0$ of an LPP is:

Options:

Region A

Region B

Region C

Region D

Correct Answer:

Region C

Explanation:

The correct answer is Option (2) → Region C

The given constraints are:

$x + 2y \geq 100$ (above the line)

$2x - y \leq 0 \Rightarrow y \geq 2x$ (above the line)

$2x + y \leq 200$ (below the line)

$x \geq 0$, $y \geq 0$ (first quadrant)

To satisfy all these constraints simultaneously, we look for the region that:

  • Is above the lines $x + 2y = 100$ and $y = 2x$
  • Is below the line $2x + y = 200$
  • Lies in the first quadrant

From the graph, only Region C satisfies all these conditions.
