A test that only one in five people can take

In everyday life, we solve different tasks every day: we consider surrender in a supermarket, we plan how much money to spend for lunch in a cafe, or we think how to hold out to a salary if you want to buy yourself a new thing.

These calculations are familiar to us, and therefore we do them very quickly. But how well do you know how to think outside of daily tasks? Are you able to put aside the stereotypes of thinking and quickly get involved in the process of finding answers to questions that are unlikely to be useful to you in everyday life?
Our test will help in this. If you want to complicate the task, try to cope with the calculations for three minutes.
