There are few issue involved here
1. Considering the capital gain in this case , it is not clear whether there was long term capital gain or short term .
2. The liability to deduct TDS under section 194IA became effective from 01/06/2013 . In this case the transaction has taken place within FY 12-13 , so not sure how the TDS was deducted and that too under 194C
3. The liability to deduct the TDS was when the payment was more tahn 50 lacs , in this case the payment was for 16 lacs only , so the TDS issue should not be there .
Any way , since the cost of acquisition is not there , it is difficult to calculate the capital gain .
