Number of Plates in Delhi

C: I’ll look at houses first. I would like to look at the income segments because people with more purchasing power will buy different dinner sets for different purposes-for example, steel or plastic for everyday use and glass or ceramic for special occasions. Also, I will take the size of a dinner set as 6. Based on these assumptions, total dinner plates used by households is 43 Mn.

For restaurants, we can look at the number of restaurants in Delhi and the number of plates used in each restaurant, assuming all restaurants are uniform.

C: The capacity of the restaurant, i.e., the number of tables and then number of plates required for each table. So, assume that the average restaurant has 20 tables and they usually provide one plate for the main course and one smaller plate for the starters. Apart from this there are plates for the dishes served too, say two on average.

C: The demand is concentrated at the end of the week because most people like to go out on weekends. So, the number of plates required to service customers on weekends would help the restaurant decide the number of plates.

C: We will observe a variation across the day, more people will go to a restaurant in the evening. Let’s say 60% of the people go in the evening from 7 pm to 11 pm for dinner and assuming that a person spends 1 hour in the restaurant and a uniform distribution, there are 60/4= 12 people in a restaurant at the peak hour. Therefore, the restaurant needs 12*(1+1+2) = 48 plates. They must also keep extras in case of breakage and damage, taking a 20% buffer that comes to approximately 58 plates.
