Question

A particular railroad found that each month 65% of its boxcars on the home trackage left to join the nation pool and 63% of its boxcars in the national pool were returned to the home trackage. If these percentages remain valid for a long period of time, what percentage of its boxcars can this railroad expect to have on its home trackage in the long run?

Answer 1

It is essential that not all of the boxcars in the nation pool returns back to the
home trackage. So, after some finite period of time the railroad will loose all of
its boxcars.
