suppose gross block as on 1/4/2009 is rs 100 ,depreciation rate is say 10% depreciation charged =rs 10 therefore net block as on 31/3/2010 is rs 90 and gross block =rs 100
thus in next year gross block remains same (assuming no addition or deduction is made) hence depreciation will again rs 10..this is like slm method
