Question

When the Production Possibility Curve would be a straight line..? Give reason also.​

Answer 1

A $\tt Production$ $\tt Possibility$ $\tt Curve$ (PPC) would be a straight line curve if all the available resources in an economy are equally efficient to produce both the goods.

At that time the $\tt Marginal$ $\tt Opportunity$$\tt Cost$ would have no change in it.
