If the objective function for an L.P.P. is z=3x-4y and the corner points for the bounded feasible region are (0, 0), (5, 0), (6, 5), (6, 8), (4, 10) and (0, 8), then the minimum value of z occurs at:

A dealer wishes to purchase a number of fans and sewing machines. He has only ₹ 5,760.00 to invest and has space for at most 20 items. A fan costs ₹ 360.00 and a sewing machine ₹ 240.00. His expectation is that he can sell a fan at a profit of ₹ 22.00 and a sewing machine at a profit of ₹ 18.00. Assuming that he can sell all the items that he can buy, how should be invest his money in order to maximise the profit? If x denotes the number of fans and y the number of sewing machines. Then which of the following are correct constituents of the associated LPP.

Consider the LPP, Minimise Z=3x+2y subject to constraints:

then which of the following is correct?

Consider the LPP, Min Z=2x-3y subject to the conditions

then the minimum value of the objective function is at the point

The feasible region for the constrains x≥0, x+y≤1 and x-y≤1, is situated in :
(A) I and II Quadrant
(B) I Quadrant
(C) II and IV Quadrant
(D) IV Quadrant
(E) I, II, III and IV Quadrant
Choose the correct answer from the options given below:
