The given question is asking about the person who will have the central position based on their level of richness. To answer this question, let`s analyze the given information:
1. X is richer than Y: This means that X has a higher level of richness compared to Y.
2. Z is richer than X: This indicates that Z is even richer than X.
3. P is richer than Z: This means that P has a higher level of richness compared to Z.
Based on this information, we can conclude that Q is not mentioned in the given information, so we cannot determine the level of richness for Q. Therefore, we can eliminate Q as an option.
Now, looking at the remaining options:
1. X: We know that X is richer than Y, but Z and P are richer than X. Therefore, X cannot have the central position.
2. Y: We do not have any information about Y`s level of richness in relation to the other individuals. Therefore, we cannot determine if Y will have the central position.
3. Z: Z is richer than X and P, which indicates that Z has the highest level of richness among the given individuals. Therefore, Z is the correct answer.
Alert - correct answer should be: There is not enough
