In 50 yuan, why does the property only charge 49.6 yuan each time?

In 50 yuan, the property charging fee is only 49.6 yuan, and the electricity consumption is different. For the owners who are in arrears with the property fees, the residential property adopts the mode that each household only sells 50 yuan electricity charges, and each household charges 50 yuan. However, the balance of each charging fee is different, sometimes only 49.6 yuan. This is because your electricity consumption is different every month, which leads to different electricity bills every month.
