| Answer:11. |
| How to arrive at solution? |
| Let us assume top row centre number is Y. |
| In the top row, the sum of the numbers is 26 + Y. |
| In the middle column, the sum of numbers is X + Y + 15. |
| According to the magic square rules, sum of each and every row, column and diagonal is the same. |
| So X + Y + 15 = 26 + Y, which implies X = 11. |
