An animal feed company must produce 200`kg` of a mixture consisting of ingredients A and B. The-ingredient A costs Rs.3 per `kg` and B costs 5 per `kg`. No more than 80 `kg` of A can be uséd and at least 60 `kg` of B must be used. Formulate the problem to minimise thé cost of mixture.

Answer

Hence the L.P.P is given by, Minimize `Z=3x+5y` Subject to constraints `x+y ge 200, x le 80, y ge 60 and x,t ge 0`
