I am preparing for am interview next week and I would much appreciate if anyone could share his thoughts on this question! Also, how would the answer change if the timeframe was in a day?
Many thanks
Hi Gaurav, thanks a lot for your comment! I would approach it as follows: I would assume that the # of hospital beds required for pregnant women is equal to the # of babies born each year. Assuming that (i) the population is evenly distributed by age (ii) the average life expectancy is 80 years and (iii) US population is 300 M people, the # of newborns per year(= to the # of hospital beds necessary for pregnant women) is 300M/80years = 3.75 M. Do you think it makes sense? Many thanks, M
If it will be done bottom up, you think we should start with what?
Here's how i would do it Equation: # of births/Day X Avg Duration a Bed is needed # of births in US is slightly over 1% of pop so 4 M new kids born year or 4M/400 = 10K births per day Now now all births are same so i would break down into normal delivery and c section. I would assume a 60:40 so 6K normal briths and 4K c section That means 6,000 X 3 Days (avg bed needed for normal) + 4,000 X 5 Days (Avg bed needed for c section) 18K + 20K = 38K making it 40K. Let me know your thoughts. I feel I am missing something.
