can go to the town and come back is:
Number of ways to travel from the city to the village = 5. (Any of the 5 roads.)
Number of ways to travel from the village back to the city = 5. (Any of the 5 roads.)
To combine these options, we multiply:
5*5 = 25.

I thought I'd mention that Mitch applied the Fundamental Counting Principle (FCP) top solve this question.
The FCP can be used to solve the MAJORITY of counting questions on the GMAT. For more information about the FCP, watch our free video: https://www.gmatprepnow.com/module/gmat-counting?id=775

Then you can try solving the following questions:

since he can take a same way for roundtrip.

5 * 5 = 25

if he must select a different way to return then number of ways = 5 * 4 = 20
