Type B requires 10 resistors, 20 transisitros and 30 capacitors. if the profit on type A circit is Rs.50 and that on type B circuit is Rs.60, formulate this problem as an LPP so that the manufacture can maximize his profit. also solve this LPP graphically to find the maximum profit.

Synthetic polymers are finding applications in almost all spheres of life and are making our life comfortable. Their large scale use has been based on their relative inertness to environment Process giving them durability for long time. However, their long durability is not altogether an advantage.

If the overuse of plastics continues, it will pose a serious threat to all of us. After reading the above passage, answer the following question : Is it advisable to continue with overuse of plastics due to their immense use in our daily life?

A manufacturer considers that men and women are equally efficient and so he pays them at the same rate. He has 30 and 27 units of workers ( male and female) and capital respectively, which he uses to produce two types of goods A and B. To produce one unit of A 2 workers and 3 units of capital are required while 3 workers and 1 unit of capital are required to produce one unit of B. If A and B are priced at Rs 100 and Rs 120 per unit respectively, how should he use his resources to maximise the total revenue? From the above as as LPP and solve graphically. Do you agree with this view of the manufacturer that men and women are equally efficient and so should be paid at the same rate?
