The local office of an app-cab company evaluates the performance of five cab drivers (Arun, Barun, Chandan, Damodaran, and Eman) for their monthly payment based on ratings in five parameters (P1 to P5) from 1 to 5. The final rating is the average of these ratings. A driver is not eligible for a bonus if they get a rating of 1 in any parameter, and must get a rating of 5 in at least one parameter to be eligible. Arun and Barun got a rating of 5 in exactly one parameter, while Chandan got a rating of 5 in exactly two parameters. No driver got the same rating in three parameters. If all five drivers get a bonus, what is the maximum possible value of the monthly payment (in rupees) that a driver gets?
