Question

user: read, write, and execute

others: none

Answer 1

To set these permissions using octal numbers, you'd use the command:

```bash
chmod 760 text.txt
```

Here's the breakdown of the octal numbers:
- User: read (4), write (2), and execute (1) = 4 + 2 + 1 = 7
- Group: read (4) and write (2) = 4 + 2 = 6
- Others: none = 0
