find total money of parent node of tree according to a particular pattern

[Ashumeerut]

actually i am working on a project in which members are added in a tree pattern, and get the payment accordingly.

My tbltestingtree structure is ass follow:

Id         ParentId        IsLeft           IsRight
             1          Null             Null             Null
             2           1                1               Null
             3           1               Null               1
             4           2                1               Null
             5           2               Null               1
             6           3                1               Null
             7           3               Null               1
             8           4                1               Null
             9           4               Null               1
             10          5                1               Null

**the problem is that initially 1500$ are given to parent when two nodes are added to its left and one to his right(2:1) . and then 500$ for each pair.**

My problem is to find the query which can return the total income of any given node.

According to figure in attachment file node 1 must get 2500$ (1500+500+500) first 500$ is for node 4 and second 500$ is for node 3.

According to figure node 2 must get 1500$ because it has two nodes to its left and one node to its right this means a ratio of (2:1). and has no pairs

According to figure node 3 must get 0$ because it does not have any nodes in ratio(2:1)

one thing has to be kept in mind that 1500$ will be the first payment and then only the other pairs will be counted, and 1500$ will be given when node has ratio 2:1(two nodes on left and one on right) but no money when ratio is 1:2(one node on left and two on right)



I have found the query which will count all the pairs below a particular node and give receiving amount according to 500$, but the query has not been able to consider the first condition that is the 2:1 condition

declare @ParentId as int
             set @ParentId=1

           create table #temp_table_name
            (
              ParentId varchar(30) null,
             )

  
          ;with Child as
           (
	    select id,ParentId from tblTestingTree where id=@ParentId
	    union all
	    Select tblTestingTree.Id,tblTestingTree.parentId from tblTestingTree 
	    inner join Child 
	    on tblTestingTree.ParentId=Child.Id
           )

      insert into #temp_table_name
      select c.ParentId  from tblTestingTree T join Child c
      on c.Id=t.Id
      WHERE ISNULL(T.ParentId, 0) <> 0 and c.ParentId!=@ParentId
      group by c.ParentId
      having COUNT(c.ParentId)>1 

      select COUNT(*)*500 as totalmoney from #temp_table_name

      drop table #temp_table_name

Please Help
