Answer:
D. Output divided by input
Explanation:
Productivity refers to how factors of production such as rent , land, labor and capital are combined efficiently to produce certain output in an economy. It is usually measured as output ratio divided by input ratio.
In other words, productivity means output gotten as a result of inputs added or given. For example, if 10 oranges are used to produce 3 litres of orange juice, then the productivity is the 3 litres of orange juice. However, if same number of oranges is used to produce say 4 litres of orange juice, we can safely say that the person who produces 4 litres of orange juice is more productive.
