How many chairs are there in the city of Berlin? Please explain your answer.
I couldn't tell you exactly how many chairs there are in Berlin, but I can try and estimate it roughly. Lets supposed there are about 3 chairs per 1 person, and the population of berlin is 3.645 million (as of 2019). Then it is likely there are 3*3.645 = 10.935 million chairs. I must stress that this is a guess and I do not actually know how many chairs there are per person.
