    as per query that well parameterized and again index seek 50 %.. please explain me?

    Well, the cost has to be somewhere. Percentages have to add to 100% or they're meaningless, so something has to have a non-zero cost percentage.

    Is the query still a problem? If no, go find a query that is a problem and worry about that query.
