Regarding sale of asset and depreciation as per IT Act

Depreciation = Rate of Depreciation * (Rs.48,14,273 --- 3,70,000)

CALCULATION OF DEPRECIATION

• WDV of an asset = Actual cost to the assesse – All depreciation actually allowed to him (included unabsorbed depreciation, if any)
• WDV of Block of Assets

Aggregate of WDV of all the assets falling within
that block at the beginning of the year                  

Add: Actual cost of any assets falling within block
acquired during the previous year                                   

Less: Money received or receivable in respect of any
asset in the block which is sold, discarded, demolished
or destroyed during the previous year                            

 = WDV at the end of the year                                        

Less: Depreciation at block rate (if WDV at the end of year is positive)    

Closing value of the block of the asset at the end of the year  

If the amount of WDV comes at a negative amount then no depreciation is allowed and the amount will be considered as capital gain and the closing WDV will be zero.

If such amount is positive and no asset exists in the block then such amount will be treated as short term capital loss and no depreciation is alllowed.

Reduce sale price of Rs.3,70,000 from opening WDV of Rs.48,14,273 from that block of assets, and calculate depreciation at rate applicable on remaining amount of block of assets i.e., Rs.44,44,273

Correct... 

Sir, i have a doubt, that if there is purchase of asset on 1-12-2017 amounting 100000. 

And if the sale stated above is made on 31-12-2017.

How to treat it ?

Sir why the sale value instead of WDV OF ASSET  suppose if sale value is 99%of asset and in substance the balance would be  more than 1% which makes no logic in it.please clarify it sir
