The Fair Market Value (FMV) of the property will need to be done as on 01.04.2001 from an authorised/registered valuer. The cost of acquisition will be the FMV calculated or Rs. 30000/- whichever is higher in your case.
The cost of acquisition calculated as above will then be indexed till 2022-23 considering the FY 2001-02 as 100. The cost inflation of index for FY 2022-23 is not yet notified by the CBDT. The cost inflation index for FY 2021-22 is 317.
e.g. If asset was sold in FY 2021-22, Indexed cost of acquisition = Cost of acquisition * 317/100.
