A company manufactures two types of hats, A and B. Market survey has indicated that the combined production level should not exceed 1200 hats per week and the demand for hats of type B is almost half of that for hats of type A. Further the production level of hats of type A can exceed three times the production of hats of type B by almost 600 units. The company makes a profit of Rs. 24 and Rs. 32 per hat of types A and B respectively. How many hats of each type should be produced weekly in order to maximize the profit?
