May I have a method for this please?

A factory bought a machine for 150,000 baht, had to pay 10,000 baht for transportation and another 12,000 baht for the installation of the machine. After 3 years of use, the condition of the machine was very deteriorating. The output of the product is of low quality. Therefore, the factory had to sell this machine at a price of 10,000 baht, with a commission fee of 5,000 baht and moving costs.

While the factory bought the machine, the depreciation was calculated by sum of year digits. The service life is set for 15 years. The final price is 10,000 baht. How much difference is the difference between the accounting depreciation charged and the actual depreciation?

Answer = 37,400 baht
