1. A farmer has 1000 acres of land on which he can grow Corn, Wheat or Soya beans. An acre of Corn costs Rs 100 for preparation requires 7man days of work and yields a profit of Rs.30. An acre of Wheat costs Rs 120 to prepare requires 10-man days of work and yield a profit of Rs.40. An acre of Soya beans costs Rs.70 to prepare requires 8-man days of work and yields a profit of Rs.20. If the farmer has Rs.1, 00,000 for preparation and can count on 8000-man days of work, how many acres should be allocated to each crop to maximize the profit?
