CROSS APPLY [dbo].[fn_split_string](ssm.subjectid,',')


Output

Your requirement is not clear (based on your comment to solution 1). Try supplying sample data for both [StudentSubMaster] and [tbfeemaster] and then give us an example of what you would expect the results to be for that sample data. One comment I will is that you are clearly storing the subjects as a comma-separated list in a single column. That is a bad design and leads to clunky code and the problems you are currently having. Store subject to student relationships in a "linking" table - that way you will not be constrained in the number of subjects by the length of the column you chose up front

1 solution

One approach would be:
SQL
SELECT SUM(x.amount) AS total_amount
FROM (
  SELECT DISTINCT  ssm.stid,fm.classid,value,fm.Amount FROM [bitcrj_database]. 
   [StudentSubMaster] as ssm  inner join  [bitcrj_database].[tbfeemaster] as fm on ssm.classid=fm.classid 
  CROSS APPLY [dbo].[fn_split_string](ssm.subjectid,',')
) x

Then you use group by and add those columns into the select.
