Use straight line method. Depreciation= (Cost-Scrap Value)/ Useful Life
Plz use the said formula for computing the Depreciation as per WDV method.
Rate of Depreciation = 1 - n √(Residual Value/Historical Cost)
n = no. Of Years = 10
Residual Value = 50000
H.Cost = 50 lacs
Rate of Depreciation = 1 - n √(Residual Value/Historical Cost)
n = no. Of Years = 10
Residual Value = 50000
