Identify the republics from the table that are located in the European part of Russia and have a Russian population percentage between 20% and 30%.

Analysis of the table and map:

• First, we need to identify which of the listed republics are in the European part of Russia. Based on general geographical knowledge and the provided map (though not all regions are clearly labeled with numbers corresponding to the table, we can infer location), the following republics from the table are generally considered to be in the European part of Russia: Chechen Republic, Dagestan, Ingush Republic, Chuvash Republic, Kabardino-Balkaria, and North Ossetia (Alania). Tuva is in Asian Russia.
• Next, we check the percentage of Russians for these identified republics.

Result:

The republics located in the European part of Russia with a Russian population percentage between 20% and 30% are:
