I do not see any "duplicates"! Why? The "number" field causes that branch no. 1 has two different records.
Please, be more specific and provide more details.

Please, read my comment first. You have to modify your SQL statement to be able to get result as expected.

Take a look at below example:

SQL

DECLARE @tmp TABLE (branch INT, number INT, val INT)

INSERT INTO @tmp (branch, number, val)
VALUES(1, 50, 200),
(5, 2, 150),
(1, 1, 200),
(3, 4, 300)

SELECT DISTINCT [branch], MAX([number]) OVER (PARTITION BY [branch] ORDER BY number DESC) AS [number],  [val]
FROM @tmp

Result:

branch	number	val
1		50		200
3		4		300
5		2		150
