Taxation of pvt. ltd.

A pvt. ltd. company have an asset ( A Property of Building) . Company is going to sale the same in  F.Y.16-17 with profit ( Short Term Gain )

Company imported the Water Jet Looms from China in the current F.Y.16-17 , depreciation will be  the reason to post a loss in the current year. 

so my questions are:

1) Can the loss adjusted against the profit on sale of asset 

2) necessary to pay advance tax?

3) how much (%) capital gain tax to be paid
