10There are three foods X, Y and Z in a restaurant. A packet of food X contains 1 unit of calcium, 2 units of protein and 3 units of carbohydrate. A packet food Y contains 2 units of calcium, 3 units of protein and 1 unit of carbohydrate. A packet food Z contains 3 units of calcium, 1 unit of protein and 2 unit of carbohydrate. If the price of foods X,Y and Z are Rs 27, Rs 16 and Rs 19 respectively. Find the price per unit of calcium, protein and carbohydrate. ( Use Cramer's rule or Inverse matrix method).
