A manufacture of electronic circuits has a stock of 200 resistors, 120 transistors and 150 capacitors and is requried to produce two types of circuits A and B. Type A requires 20 resistors, 10 transistors and 10 capacitors. 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.
