The Hospital Bed Question

THE guesstimate question is a usual type of question that you can expect to be asked when interviewing for a position at a consulting firm.

Here is one to test your mettle.

The Hospital Bed Question

The question is this: How many hospital beds are required in New York city to provide for all of its pregnant women? 

You can assume that:

  1. pregnant women stay in hospital for one night only (American hospitals are very expensive); and
  2. hospital beds in New York are used exclusively by New York residents (no sharing).

If you are game to test your skills, then this is what you need to do.

Please respond in the comments below, covering the following in your answer:

  1. set out the steps that you would take to answer the question;
  2. note any additional assumptions that you would make at each step; and
  3. provide a final numerical guesstimate to the question.

To spice things up, I will be happy to send the best answer (as judged by me) a copy of an interesting book by Lawrence Weinstein (nuclear physicist) and John Adam (professor of mathematics). The book is called Guesstimation: Solving the World’s Problems on the Back of a Cocktail Napkin.

Note that the comments section remains open for 14 days only, so you have a limited time in which to respond…

Happy guesstimating.
