Analysis and Solution

To determine which subject each of the three comrades teaches in which city, we need to analyze the given information:

- Vladimir does not work in Ryazan. - Igor does not work in Tula. - The Ryazan teacher does not teach physics. - Igor does not teach mathematics. - The Tula teacher teaches literature.

Let's break down the information step by step to find the solution.

Step 1: Vladimir's City and Subject

From the given information, we know that Vladimir does not work in Ryazan. Therefore, he must work in either Tula or Yaroslavl.
