A circuit does not "have" 24 volts "on one end." You can measure voltage between two points in the circuit, and get a reading of 24 volts. But what two points are you talking about? What exactly is meant by "on one end"? If you can't show us a picture of the circuit, annotated with where the measurements were taken, then we are not going to be able to help you.
Consider asking for an explanation of what you are looking for. Most classes have significantly better formulated homework problems than this. With the information we have, the most likely explanation is you have missed some of the information about the problem.
