Question

Write the numbers 36,37,38,39,40,51,42,43 and 44in the sqaures so that each row column equal to120

Answer 1

-- I believe there's a typo in your question, and
you meant to type ' 41' instead of ' 51 '.

-- Here's how to arrange them:

-----------------------
| 43 | 36 | 41 |
-----------------------
| 38 | 40 | 42 |
-----------------------
| 39 | 44 | 37 |
-----------------------

The diagonals also add up to 120.
