A manufacturer produces nuts and bolts. It takes 1 hour of work on machine A and 3 hours on machine B to produce a package of nuts. It takes 3 hours on machine A and 1 hour on machine B to produce a package of bolts. He earns a profit of Rsl7.50 per package on nuts and Rs 7.00 per package on bolts. How many packages of each should be produced each day so as to maximise his profit, if he operates his machines for at the most 12 hours a day?

A manufacturer produces pend and pencils. It takes 1 hour of work on machine A and 2 hours on machine B to produce a package of pens while it take 2 hours on machine A and 1 hour on machine B to produce a package of pencils . He earn a profit of Rs. 4.00 per package on pens and Rs. 3.00 per package on pencils. How many packages of each should be produce each day so as to maximize his profit, if he operates his machines for at most 12 hours a day ? Formulate the above information mathematically and then solve.

A manufacturer produces nuts and bolts. It takes 2 hours work on machine A and 3 hours on machine B to produce a package of nuts. It takes 3 hours on machine A and 2 hours on machine B to produce a package of bolts. He earns a profit of Rs. 24 per package on nuts and Rs. 18 per package on bolts. How many packages of each should be produced each day so as to maximize his profit, if he operates his machines for at the most 10 hours a day. Make an L.P.P. from above and solve it graphically ?
