How many people have visited the most important 100 places in the world

Victor asked on Jan 26, 2018 - 1 answer

Dear community, I had an interview where I got a case that got me completely off: there is a book called the 100 places you should visit before dying. How many people have already visited all of them? (No more information at all)

I couldn’t sort it out and since then I couldn’t either figure out anyway way to approach and solve it.. would love to hear your thoughts on this one

Thanks in advance for any help

It's an estimation problem and clearly an interesting one. The way how I will tackle will be

  1. First to understand what places are we talking about? (nature, buildings, historic)
  2. Since all 100 would fall into a similar cateogiry, I would choose any 1 and would estimate how many people visit it- annual/daily basis
  3. Understand what sort of people will likely to go to another 99 places- die hard tourist, art loves/ history enthusiast
  4. Once you get the number- could be like 20%, then you can further go that out of those 20% not everyone would time/finances for all 100 places- and the number would further drop down
  5. This number should be the final answer unless I am missing anythign else (Assumption)

I look forward to read what others have to say
