What is the relation between these tables ?

You need to join the tables to get the desired result.

I tried following query but its giving me wrong total
''''''''''''''''''''''''''''''''''''''
SELECT Prd.Item_Name, Sum(P.Piece_No) AS PStock, Sum(D.Itm_Qty) AS SoldStock, Sum(R.Itm_Qty) AS RefStock, Sum(P.Piece_No)-Sum(D.Itm_Qty)-Sum(R.Itm_Qty) AS Avl_Stock
FROM Refund_Detail AS R, (Product AS Prd INNER JOIN Purchase_Detail AS P ON Prd.Item_Name = P.Item) INNER JOIN Detail_Description AS D ON Prd.Item_Name = D.Item
WHERE (((Prd.Item_Name)=[P].[Item] And (Prd.Item_Name)=[d].[Item]))
GROUP BY Prd.Item_Name;
