I do not believe that the first answer is really what the questioner is looking for.
In economics, the "economic problem" is defined as the problem of deciding what to make, how to make it, and who to make it for. You can see this in any economics book, for example, here.
A traditional economy is one of the three types of economy (traditional, market, command). In a traditional economy, the questions that make up the economic problem are answered by tradition. What will we make? We will make whatever our parents made. If our parents farmed, we will farm. How will we make it? Again, however our parents did. We will not try to innovate. We will just do things as they have always been done. For whom will we make it? Again, tradition. We will probably make it for ourselves. If it is traditional, we will give some to the village elders or the chief. We might give some away to relatives. We will not be driven by concerns about profit or anything like that.
So, in terms of economics, this is how tradition answers "the economic problem."
