Problem 9. Each knight gives one affirmative answer to four questions, while a liar gives three. In total, there were $95+115+157+133=500$ affirmative answers. If all the residents of the city were knights, the total number of affirmative answers would be 200. The 300 extra "yes" answers come from the lies of the liars. Thus, the number of liars is $\frac{300}{2}=150$.

Let $k$ be the number of knights living in District A, then $95-k$ is the number of affirmative answers to the first question given by the liars. Therefore, the number of liars living in District A is $150-(95-k)=k+55$. Similarly, we find that in District B, there are 35 more liars than knights, and in District G, there are 17 more liars than knights.

In District V, there are fewer liars than knights.
Answer: in quarter A, by 55 people, in quarter B by 35 people and in quarter $\Gamma$ by 17 people.
