From the table below, the average product of the 3rd unit of labour is

Explanation

This is because the average product (AP) is found by dividing total product by the input of labour. For example, a company that produce 100kg of product with 10 workers has an average product of 10. For a detailed explanation, taken a company A for example. If company A employs only one worker and with one worker, total production is 20kg each hour. This gives an average product of 20kg. Now if company A employs two workers and the total production is 50kg, the average product for the two workers give 25kg. Also when company A employs three workers and the total hourly production increase to 90kg, these means 30kg is the average product for the three workers and so on. In this case, 3 workers produce 150kg of output therefore, the Average product of labour for the 3rd unit is 50kg.
