Straight Line Method Depreciation

Rs. 3,167 p.a depreciation 

Thank u so much Mr. Navern.
One more clarifications; Plant & Machinery purchased on June 2018 and started amortization for the same month onwards. After 15 months (Aug 2019) we received a notice from Customs regarding short duty valuation of particular Plant & Machinery now customs is asking to pay 75K against that FA.
Machinery Cost 1000000
Salvage Cost 50000
Net Value 950000
15 months Depreciation Cost 148,450
NBV after 15 months 851,550.
How so we add this customs Duty in the FA?
NBV after 15 months or From the date of Acquisition? From the date of Acquisition means we already closed Financial Statement, if AuG 2019 how do we calculate?

You should add 75000 to 851550 and depreciate this amount to remaining life.

Thank u so Much Manish Ji
