Let number of tennis racket be made is X and number of cricket bat be made is Y

Since, tennis bat requires 1.5 hours and cricket bat requires 3 hours of machine time. Also, there is maximum 42 hours of machine time available.

∴1.5X+3Y≤42

⇒X+2Y≤28   ...(1)

Since, tennis bat requires 3 hours and cricket bat requires 1 hours of craftmans time. Also, there is maximum 24 hours of craftmans time available.

∴3X+Y≤24   ...(2)

Since, count of an object can't be negative.

∴X≥0,Y≥0   ...(3)

We have to maximize profit of the factory.

Here, profit on tennis racket is 20 Rs and on cricket bat is 10 Rs

So, objective function is Z=20X+10Y

Plotting all the constraints given by equation (1), (2) and (3), we got the feasible region as shown in the image.

 Corner points

 Value of Z=20X+10Y

 A (0,14)

140

 B (4,12)

 200 (maximum)

 C (8,0)

 160

Hence,

(i) 4 tennis rackets and 12 cricket bats must be made so that factory will work at full capacity.

(ii) Maximum profit of factory will be 200 Rs

A manufacturer makes two types of toys A and B. Three machines are needed for this purpose and the time (in minutes) required for each toy on the machines is given below:

Each machine is available for a maximum of 6 hours per day. If the profit on each toy of type A is Rs.7.50 and that on each toy of type B is Rs.5, show that 15 toys of type A and 30 of type B should be manufactured in a day to get maximum profit.
