How to find maximum value

[Azwaliyana]

I want to display the maixmum percentage and the mounted but I do not know the command.
because the file is not in csv. It is a txt file and I use multikv to extract the field.

Can you give an example of the data you have

Please can you share as text in a code block </> rather than an  image?
