Hi,
There is a question in Kaplan’s old revison kit titled, ‘Private Hospital’. It’s pretty lenghty, so reproducing it will take quite some time.
I need to know about one of it’s constraints, which is x>y. When it’s plotted on the graph it’s x=y. This line is plotted on like a 45 degree angle. My question is, do we assume the values of x and y? like x=20, y=20 and x=40, y=40, when plotted these values gives 2 points and thats how the line is made..
Is that right? Do we assume the values?Thanks in advance.
May 28, 2012 at 6:37 am #98474for any equation, you can assume any value for x and then find corresponding value of y.
take x=0, then find corresponding value of y. here , it would be 0.
take another value for x, say 20, then find corresponding value of y. here it would be 20.
two such points are enough to draw a line.
next factor is to find feasible region. for x>y, it would be below the line. as x can take any value greater than y. for x
