Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

The production possibility curve (PPC) is the collection of all combinations of two goods in various quantities that can be produced utilising completely all the resources available at given level of technology. The shape of PPC is downward sloping concave usually. 1. Downward sloping means more of one good can be produced only when the production of other good is reduced. This is because resources are constant. 2. Concavity means the rate of change of slope is decreasing. This means that greater quantity of Good Y will have to be sacrificed to produce every successive unit of Good X.
