    1. How many records the table has and what kind of table it is i.e. means read only or having lots of DML operations.

    2. What is the fill factor for the index ?

    First thing. Is that query a problem?

    The percentages in the plan must add up to 100%, so the fact that a scan is 87% is not necessarily a problem.

    If the query is a problem, then please post query, table definitions, index definitions and execution plan, as per http://www.sqlservercentral.com/articles/SQLServerCentral/66909/
