Production possibilities curve demonstrates that:
• There is a limit to what the society/individual can achieve, given the existing institutions, technology and resources.
• Every choice the society/individual makes has an opportunity cost – to get more of one good, we need to give up some of another good – every choice has a tradeoff.

PPF also illustrates the concept of efficiency. The combination of goods depicted on the curve are attainable only if all the resources are fully employed, with the most efficient means of production possible. All of the points on the frontier are said to be productively efficient, because they are fully utilizing the economic resources that they have

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. Given by:
Average product= \(\frac{Text{Total product}}{Text{Variable product}}\)

This question is a little bit tricky to answer because out of the 4 options provided only one is not a
