Question:
In a market, there are 3 cash registers serving customers (K1, K2 and K3). The tail of each vault is separate (Q1, Q2 and Q3). Safes K1 and K2 are always open. The K3 safe is only opened if there is a request from the customers. When customers who have finished their work in the market and head to the cash register see that two customers are waiting in queues in Q1 and Q2 queues (except for those who are traded), they request the K3 cash box to be opened and these requests are immediately met by the management. The K3 safe opened in this way is closed again when the total number of customers waiting in Q3 and traded in K3 is 0 (zero). Customers arriving at the cash registers go to the cashier with the shortest queue length. If the queue lengths are equal, customers prefer Q1, Q2 and Q3 queues, respectively, due to proximity to the exit (It is assumed that there is no transition from one queue to another queue). Arrival times of 20 customers coming to this cash register system are given in the cell range "I6:I25" in seconds. The transaction times in the cash register entered by these 20 customers are given in the cell range "L6:L25" in seconds. Fill in the green fields in Table 1 and Table 2 according to this information and rules.
