We assume that in a village there are farmers, carpenters, and tailors, who provide the three essential goods: food, housing, and clothing. Suppose the farmers consume 2/5 of the food (produced by farmers), 1/3 of the housing (produced by carpenters) and 1/2 of the clothes (produced by tailors). The carpenter consumes 2/5 of the food, 1/3 of the housing, and 1/2 of the clothes. The tailors consume 1/5 of the food, 1/3 of the housing, and no clothes. Assume this is a closed Leontief model. If we know that the tailors produce 560 units of clothes, then the farmers produce units of food, and the carpenters produce units of housing.
