LTCG on selling a property (plot) which was bought below circle rate

Hi All,

I could not find answer to one of my query while searching on this forum s i am posting a question here as below:

I have purchased a plot within local development authority boundaries of my city on 22nd Feb 2012 for 1500000 INR but the circle rate value of plot at that time was 2750000 INR. We paid stamp duty charges as per circle rate value at that time.

I have now sold the plot on 8th April 2022 for 6750000 INR (current circle rate value of plot is also 6750000 INR). Now while calculating the LTCG (Long term capital gain), the original non-indexed purchase price should be considered as 1500000 INR + stamp duty or 2750000 INR + stamp duty?
