Can a company buy lot of Fixed asset and claim deprecaition more than it's income? and later sell ?

I am confused

Can company buy lot of assets to claim high depreciation over say next 5 years and then sell it again at orignal price or more ? for eg Buildings 

1. If sold at same orignal price  after 5years of claiming depreciaition  , it will be taxed
2. but I am thinking after 5 years even if charged with same tax amount percentage, it would have lost time value of money ( The tax amount would have lost time value of money )
   
   I think - we would have claimed high depreciaiton benefit & still pay less value of taxes in terms of time value 

eg

iF Building was 100 cr , we claimed 50 crs depriciation over next 5 year and then sold it for 100 cr , with now tax on gain 50cr @ 30% =15cr

but this value is discounted at 10% = 15/ (1.10)^5 =9.31 cr 

and

will revaluation help me in capital gains tax ? Do I pay tax on gain from tax base amount or difference between revaluation amount & sold amount

any notes and content to understand better will be higlhy appericiated .

Thank you
