[Plutor]

Not necessarily (and actually that would be a terrible answer. The highest rent in Monopoly with a hotel is $2000, and I would hardly call that a "fortune".

The point of the question is to establish how well you gather additional information when the initial description is unsatisfactory. Anyone who's been an engineer knows you have to do this every single day.

(Not that it's a good interview question.)

Monopoly was first published in 1935 and the prices haven't increased since. That makes the cost of a stay at the most expensive hotel $34,000 in today's money, which is far more than I'd ever pay to stay at a real hotel...

Ignoring inflation, you can compare the price of staying at that hotel with buying the land it's built on for a relative estimation of the cost.
