What this question tests

Estimation using population, tourism volume, and hotel room supply logic for a specific well known city.

Estimate annual visitor volume, around 60 million tourists a year including day trippers and overnight visitors.
Estimate the share needing overnight stays and average length of stay to get total room nights demanded annually.
Estimate average hotel occupancy, around 85 percent, to back into total room nights supplied.
Estimate average hotel size, around 200 rooms in a dense city.
Divide total rooms by average hotel size to estimate the number of hotels, stating the result as a range.

Anchors on visitor volume, a defensible starting point for a tourism heavy city, rather than guessing hotel count directly.
Shows the chain of math, 40 million overnight visitors times 3 nights average, divided by 365 days and 85 percent occupancy, gives a total room count, then divided by 200 rooms per hotel.
States a final range, for example 500 to 700 hotels, noting it can be sanity checked against known figures.
