Vitamins A and B are found in two different foods F_1 \ a n d \ F_2 . One unit of food F_1 contains 2 units of vitamin A and 3 units of vitamin B. One unit of food F_2 contains 4 units of vitamin A and 2 units of vitamin B. One unit of food F_1 \ a n d \ F_2 cost Rs. 50 and 25 respectively. The minimum daily requirements for a person of vitamin A and B is 40 and 50 units respectively. Assuming that anything in excess of daily minimum requirement of vitamin A and B is not harmful, find out the optimum mixture of food F_1 \ a n d \ F_2 at the minimum cost which meets the daily minimum requirement of vitamin A and B. Formulate this as a LPP.
