Seven friends-Yevhen, Nina, Ruslan, Larysa, Ilya, Galyna and Oleg choose the university where they will study. They choose between two options, namely KNU and KPI. Friends decided to follow the following rules: 1) If Oleg and Nina choose to study at the same university, then Ruslan chooses it as well 2) If Larysa does not choose the university, then Ilya doesn't choose it either. If Ilya choose KNU, which of the following statements cannot be true? Ruslan choose KNU Oleg choose KPI Larysa choose KPI Yevhen choose KNU Galyna choose KPI

Ответ:

If Ilya chooses KNU, then Oleg cannot choose KPI. According to the rules, if Oleg and Nina choose the same university, Ruslan has to choose it as well. Since Ilya has chosen KNU, it means that Oleg and Ilya have chosen different universities, which contradicts the rule. Therefore, the statement "Oleg chooses KPI" cannot be true.
