Grid Based Puzzle

Friends based on the emails I am getting I think most of you like creative and interesting logical puzzles.  So I am presenting another very interesting grid puzzle one for you.

Grid Puzzle

Below is a very special grid, around each shaded number are 8 white squares. However, each white square should have a number from 1 to 7. Once filled in, these 8 numbers will sum to the shaded number. In addition, once completed correctly, no row nor column will contain a duplicate number within a white square. For example, the top row may be 5 6 4 2 3 1 7, etc. hence no digit repeated (similar to Sudoko)

Figure-1

Try to fill all the blank spaces. Leave your answers below by writing the numbers row-wise.

    I am giving you the answer. But before looking into it, give it a try by yourself. I solved this using excel (it’s fun that way)

    6 26 5 35 3 37 1
    1 2 6 3 4 7 5
    4 31 2 36 7 39 6
    3 6 7 2 5 1 4
    5 38 4 26 1 24 2
    7 5 1 4 2 6 3
