Q23 of 46 Page 1

A small firm manufactures gold rings and chains. The total number of rings and chains manufactured per day is atmost 24. It takes 1 hour to make a ring and 30 minutes to make a chain. The maximum number of hours available per day is 16. If the profit on a ring is Rs. 300 and that on a chain is Rs 190, find the number of rings and chains that should be manufactured per day, so as to earn the maximum profit. Make it as an L.P.P. and solve it graphically.

Let x be the number of gold rings and y be the number of chains manufactured.


LPP is:


MAX Z = 300X + 190Y


Now


X+Y≤24


And


2X+Y≤32


Also X≥0 , Y≥0


Thus feasible region,




So for maximum profit 8 gold rings and 16 chains should be manufactured.
