Hierarchy with calculation

Hi
I need to Return values with hierachy sum.
I have
provided the tables with data and result expected
below

============
CREATE TABLE 
============


CREATE TABLE 
[dbo].[Travel_Master]( 
[Load_Id] [int] NULL,
[Mode_Id] [nchar](2) 
NULL,
[Mode_Info] [nchar](10) NULL,
[Has_Nodes] [nchar](3) NULL
) ON 
[PRIMARY] 

CREATE TABLE [dbo].[Travel_Quantity]( 
[Load_Id] [int] 
NULL,
[Mode_Sno] [int] NULL,
[Mode_Id] [nchar](2) 
NULL,
[Mode_Parent_Sno] [int] NULL,
[QA] [numeric](18, 0) NULL,
[QC] 
[numeric](18, 0) NULL,
[QY] [numeric](18, 0) NULL
) ON [PRIMARY] 



============
INSERT DATA INTO TABLE 
1
============

============
RULES
============
QA or QC will
be present in the Parent Node where we have 'Has_Nodes' = Yes
QY will be data
of the Leaf in Tree, which has to be muliptied against Its
roots.

============
RULES
============

The parent data will have either QA or QC
Child will have data in QY.

QA or QC will be present in the Parent Node where we have 'Has_Nodes' = Yes
QY will be data of the Leaf in Tree, which has to be multiplied against Its roots.
Where the Parent is -1, those records are root values. If no data below, then they don't have child.

Parent Data can be in QA or QC, where in the Child data will be in QY in source table.
 The result in QY should be displaying child data multiplied against the QA or QC column which has data 

========================
EXPECTED
RESULT
