You have a grocery delivery service (similar to Blinkit or Instamart) that ships pan India within 24 hours. Without searching online for specific details, estimate how many 1-ton trucks you need to operate this service using the power of logic based on assumptions (e.g., assuming that India has 1.4 billion people of which you have a 25% market share).

Population of India- 1.4 billion
Market Share- 25% / 350 million
Let us assume that an average family size in India is 4
No. of Families- 350/4 = 87.5 million
Since we are in the business of Grocery Delivery Service, we can assume that a household (family) would place an order once in 2-3 days (barring the need for milk everyday). Hence assuming 2.5 days here
Number of orders everyday- 87.5/2.5= 35 million
Average Weight of an order- 3kg
Weight being transported across India everyday- 35 million * 3= 105 million kg / 105,000 tons
Since Trucks are used only for Mid Mile deliveries in the business that we are in, let us assume that a Truck takes 3 hours to make a delivery from the warehouse to a dark store and back. The truck is operational for 9 hours a day that gives it 3 round trips.
Weight capacity of a truck (assuming 100% truck utilization)- 1 ton
Hence, we can estimate the number of trucks required by simply dividing the weight being moved across the country and number of trips being made by the trucks- 105,000/3 = 35,000 trucks
CQ:
Consider only grocery
Where are the dispatch locations are situated -> assume only Delhi
Destination is PAN India - Yes
Stock availability - 100%
Fill rate - 100%
Approach:
Population -> 1400Mn
No of families
Urban -> 560Mn
No of orders made per family/week -> 2
No of total orders -> 1120 Mn/week
Blinkit estimate -> 280 Mn/week
Avg order weight -> 200gm
Total order weights for Blinkit -> 140 Mn kg/week
No of trucks required per day -> (140 *10^6)/(10^3 * 7) = 20 * 10^3 = 20,000
Rural -> 840Mn
No of orders made per family/week -> 1
No of total orders -> 840 Mn/week
Blinkit estimate -> 210 Mn/week
Avg order weight -> 100gm
No of trucks required per day -> (210 *10^6 *0.1)/(10^3 * 7) = 30,000
Total no of trucks reqd to operate each day then is 40,000
