Capital Budgeting under Risk and Uncertainties^135
Given the range and most likely value of basic variables, we can study the impact of
variation in each variable on net present value, holding other variables constant at their
most likely levels. To illustrate the nature of this analysis we shall look at the relationship
between (i) r and NPV, and (iii) P and NPV.
r and NPV The reltionship between r and NPV given the most likely values of other
variables is
NPV =
