Show Largest and Average amounts same table

[#1]

I have a requirement where i have below details:

Company	Person	Amount
ABC	A	100
ABC	B	200
ABC	B	300
XYZ	C	300
XYZ	C	100
XYZ	D	500

I have to show the data in below format in straight table:

Company	Person	Largest Amount	Average Amount
ABC	B	300	200
XYZ	D	500	300

Basically i have to show the largest amount per company and the corresponding name of the person.

Average amount is just the average of all amounts per company.

I'm using this expression for calculating Largest amount:

MAX(AGGR([Amount]), Company, Person)

And this expression for Average amount:

AVG(AGGR([Amount]), Company, Person)

So, i'm getting the correct amounts but i'm not getting the corresponding Person Name, its coming as some random Person Name.

Can anyone help please?
