QUANTITATIVE METHODS

1) A manufacturer o f baby doll s makes three types o f doll s: Doll A , Doll B , and Doll C

Processing o f these doll s i s done on three machines , M1 , M2 and M3 . Doll A requires 2 hours on ma chine M1 and 3 hours on machine M3 .while doll C requires 5 hours on

ma chine M2 and 4 hours on machine M3 . There a re 8 hours o f time per day available on Ma chine M1 , 10 hours o f time available on ma chine M2 and 15 hours o f time per day available on machine M3 , The profit gained from doll A i s R s 3 per doll , from doll B is R s 5 per doll and from doll C is R s 4 per doll .

What should be the daily production o f each type o f doll s? Which ma chine(s) would be idle ac cording to this plan? By how much?
