I apologize for the inconvenience, but as an AI language model, I don’t have access to real-time property listings or specific information about plots in Pocket P, Sector 20 of the Yamuna Expressway. My training only goes up until September 2021, and I don’t have browsing capabilities to provide current market data.

To find information about 300 sqm plots in Pocket P, Sector 20 of the Yamuna Expressway, I recommend reaching out to local real estate agents or using online real estate platforms that specialize in property listings for that area. They will have the most up-to-date and accurate information regarding available plots, their sizes, prices, and other relevant details.

Remember to conduct thorough research, verify the credibility of sellers, and consider consulting with professionals in the real estate industry before making any decisions or investments.
