Question
Maximize Z = 4x + 3y
Subject to
$3\text{x}+4\text{y}\leq24$
$8\text{x}+6\text{y}\leq48$
$\text{x}\leq5$
$\text{y}\leq5$
$\text{x},\text{y}\geq0$
✓

Answer


$\text{3x}+\text{4y }\leq24\ ;$ when x = 0, y = 6 & when y = 0, x = 8, line AB
$\text{8x}+\text{6y }\leq48\ ;$ when x = 0, y = 8 & when y = 0, x = 8, line CD
Plotting $\text{x}\leq5$ given line EF; Plotting $\text{y}\leq6$ given line AG
The feasible area is 0, 0 - C - H - G - E
Corner point Value of Z = 4x + 3y
0, 0 0
0, 6 18
3.4, 3.4 24
5, 1 23
5, 0 20
The maximum of Z = 4x + 3y, occurs at x = 3.4, y = 3.4

A diet for a sick person must contain at least $4000$ units of vitamins, $50$ units of minerals and $1400$ units of calories. Two foods $A$ and $B$ are available at a cost of Rs. $5$ and Rs. $4$ per unit respectively. One unit of the food A contains $200$ units of vitamins, $1$ unit of minerals and $40$ units of calories, while one unit of the food $B$ contains $100$ units of vitamins, $2$ units of minerals and $40$ units of calories. Find what combination of the foods $A$ and $B$ should be used to have least cost, but it must satisfy the requirements of the sick person. Form the question as LPP and solve it graphically.
