Guesstimate: sizing Zomato's food-delivery rider fleet in Bengaluru

Size Zomato's food-delivery rider fleet in Bengaluru (Bangalore), India: roughly how many delivery partners does it have? ```hint Decide what you are counting Riders on the road at one moment, riders who work on a given day, and everyone who delivers over a week are very different numbers. Settle which one you are giving, then pick the side of the market you can reason about most confidently. ``` ### Clarifying Questions - Do you want riders on the road at the busiest moment, partners who work on a typical day, or everyone who delivers at least once in a week or month? - Food delivery only, or also riders carrying grocery and quick-commerce orders? - Do partners who also deliver for rival apps count, and do part-timers count the same as full-timers? - Should the estimate cover the city proper or the wider metro area, and a normal day rather than a festival or a heavy-rain evening? ### What a Strong Answer Covers - A precise definition of the count, and why that definition was chosen - An equation linking population, order demand, Zomato's share and rider capacity - Round, labeled assumptions with reasoning, including the peak-hour effect and how many orders a rider completes per hour - Clean arithmetic, including the step from riders needed at the peak to the total number of partners - A sanity check from an independent angle, and which assumptions move the answer most ### Follow-up Questions - How would the number change on a monsoon evening or a festival night, and what could Zomato do to cover the gap? - If Zomato wanted a smaller fleet without slower deliveries, which terms in your equation would it try to change? - How would you estimate the same fleet from the rider side instead of the order side?
