Market tests and available
resources have indicated that the combined production level should not exceed 1200
dolls per week and the demand for dolls of type B is at most half of that for dolls of
type A Further, the production level of dolls of type A can exceed three times the
production of dolls of other type by at most 600 units If the company makes profit of
Rs 12 and Rs 16 per doll respectively on dolls A and B, how many of each should be
produced weekly in order to maximise the profit Summary

non-negative and satisfy a set of linear inequalities (called linear constraints)
