Based on how the city and its infrastructure, what would you estimate its GDP(PPP) per capita in USD to be?

For context, I made this map of districts in AP by GDP(PPP) per capita: https://www.reddit.com/r/andhra_pradesh/s/QoWu7xfKih However, in the comments, I got rightfully called out for using India’s PPP conversion factor of 20.29 for all the districts even though the cost of living varies by state and by district. So then, what would Vizag’s actual GDP(PPP) per capita be of $34,800 is too high?
