Sudoku Nov, 2nd week

From this month onwards, I will post the Sudoku on weekly basis for those who enjoy this game as I do. Anyone who like to discuss the answer or get hint, can drop me a comment anytime. :)

Rule: Fill the grid so that every row, every column and every 3x3 box contains the numbers 1 to 9.


Comment: I find this combination pretty medium. There should not be any diffiulties in solving.
