Question

Food delivery agents Aman, Boni, Chan, Dong and Eman were assessed on five parameters $\text{P1}$ to $\text{P5.}$ They received an integer rating between $1$ and $5$ for each parameter. None of them received the same rating in four or more parameters. Everyone received a score of $1$ in $\text{P2}$ or $\text{P5.}$ All of them received the same rating in at least two parameters. The partial information related to the ratings are given in the table below. 

$$\begin{array}{|c|c|c|c|c|c|} \hline \text{Name} & \text{P1} & \text{P2} & \text{P3} & \text{P4} &\text{ P5} \\ \hline \text{Aman} & & & & 3 & \\ \hline \text{Boni} & 4 & & & & \\ \hline \text{Chan} & & & 5 & & \\ \hline \text{Dong} & 2 & & & & \\ \hline \text{Eman} & & & & 1 & \\ \hline \end{array}$$ 

Considering the above information, answer the following questions:

1. What is the maximum average rating Boni could have achieved across all the five parameters?
