It's a busy day in the market, but there are only two cashiers that are beside one another. Cashier A takes 1 minute to facilitate a customer, while Cashier B takes 1 minute and a half to facilitate a customer. There were 100 shoppers, waiting to purchase some goods. Assuming that all of them are in a hurry, and that they finished at the same time, how can you facilitate a faster service?

The fastest time 5 customers can be facilitated is 3 minutes, which is accomplished when cashier A facilitates 3 customers and cashier B facilitates 2 customers. Thus the fastest time 100 customers can be facilitated is 60 minutes, where cashier A facilitates 60 customers and cashier B facilitates 40 customers.

Now this is the answer.

Basically, a "Y" method, because one cashier will always be facilitating a customer. Some people go for the easy answer of saying 50 each (75 minutes) or something like that. The worst one is finding a hole instead of solving (Ex. get more cashiers)
