join with the name is not correct way of joining. disagree with this solution.

I think it is better to use Stuid to establish relation between Studetail and Amount table like

Amount Table
id int,
amount float

in which case the following query can be used to get the result sought in the question

SQL

SELECT Studetail.Stuid, Studetail.name, Studetail.college, Stuadd.address,
    (SELECT SUM(Amount) FROM Amount WHERE Studetail.Stuid= amount.id) AS TotalAmount
FROM Studetail INNER JOIN Stuadd ON Studetail.Stuid = Stuadd.id
