In the given figure, shaded region represents the feasible solutions to a LPP problem. The constraint represented by AD is :

$3x+y≤30$ $3x+y≥30$ $3x+y>30$ $3x+y<30$

$3x+y≥30$

The correct answer is Option (2) → $3x+y≥30$ Students will be unable to solve at this resolution $D(0,30),A(10,0)$ equation of line → $\frac{y-30}{x}=-\frac{30}{10}$ $⇒3x+y=30$ as shaded region is at upper half so $3x+y≥30$
