Create a set of the two members in a crossjoin and then do a sum on it.
So something like
WITH MEMBER [YourCalculation]
AS
SUM
(
{([Country].[Country].&[India] , [State].[State].&[Andhara])}
,
[Amount]
)
Although of course you have provided very little detail so I've had to provide a generic example - in other words don't just copy and paste that code, it won't work. Also it's pretty poor form for you to just ask people to write your code for you 😉
