For linear programming you are required to understand that when to use linear programming because F5 is little bit tricky paper…
well am telling you from Kaplan book hope it will help you:)
first of all when using linear programming for finding optimal solution.
you will have to follow, following steps.step#1: identify veriables
let x= number of units or demand as given in question
y= number of units or demand as given in question
step#2: define objective function.
in profit maximising question the objective function may be
contribution/unit of X + cont/unit of Y= C
note,where C is maximum contribution.
Step#3: Define constraints.
in this step you will have to formulate all the given information relating to resources in form of equations.Step#4: Graph
In this step you will have to solve the above equations by putting X=o for the value of Y and putting Y=0 for the value of X which you defined in step#3
after getting all values of X and Y from each equation, then plot them on graph .
after plotting them on graph you will have to plot Iso-contribution line(in dotted form) you may find the points of iso-contribution line by solving contribution line which u made in Step#2.
for example suppose a contribution line
20X +40Y= C (suppose this line you made in step#2)
now, see how to solve this
20X + 40Y= 800 (i.e 20*40=800)
now by putting X=0 we get y=20
and by putting Y=o we get X=40
after plotting these points on graph in dotted form put a roller on that dotted line and then move it with same slope on graph then the point which is farthest from the origin and lieing in feasible region will be the optimum point.step#5 comment or result.
in this step you will have to conclude that which point is giving max. contribution .
then show the contribution by putting the values of X and Y in Equation A.Thats it…
you can ask if you find any difficulty in these steps:)
