Vitamins {\A} and {\B} are found in food {\F}_{1} and {\F}_{2} . One unit of {F}_{1} contains 20 units of vitamin {\A} and 30 units of vitamin B. One unit of food {\F_2}, contains 60 units of {\A} and 40 units of B. Costs per unit of {F}, and {F}_{2} are \₹ 3 and \₹ 4 respectively. The minimum daily requirement of vitamin {\A} and {\B} is 80 and 100 units respectively. Problem is to determine the mixture of food \F_{1} and \F_{2}, which meets the requirement at minimum cost by assuming that x_{1} units of food \F_{1} and \X_{2} units of food \F_{2} are required to fulfill the need of vitamins. The constraints are
