35. Think of a number written in one column:

| 10 | 23 | 16 | 29 | 32 |
| ---: | ---: | ---: | ---: | ---: |
| 27 | 15 | 28 | 31 | 9 |
| 14 | 32 | 30 | 8 | 26 |
| 36 | 24 | 12 | 25 | 13 |
| 23 | 16 | 24 | 17 | 30 |

How to guess the thought number by the sum of the numbers (excluding this number) in the row or column where the number is written? (Propose this trick to your friends.)
35. The sum of the numbers in each row or column is 110. Therefore, if, for example, the number 30 is chosen, then the sum of the numbers in the row without it: $14+32+8+$ $+26=80$. If you are given this sum, then you find $110-80=30$.
