how is solving a fake problem to solving a real problem

I believe that solving this kind of problem is similar to problems in real life because when trying to find an answer you must first understand a problem then you have to come up with a plan and after finally creating the best plan you put it in to motion and solve the question.
for example, when I want to buy something expensive I first ask myself how is it that Im going to reach this amount and by what time? then I calculate the amount of income i receive and the amount of time it would take to reach my goal. finally I carry out my money saving plan and reach my goal.
