Explanation: 
The employees with IDs 2 and 8 get 0 bonus because they have an even employee_id.
The employee with ID 3 gets 0 bonus because their name starts with 'M'.
The rest of the employees get a 100% bonus.
```

SELECT 
  employee_id, 
  (CASE WHEN
      MOD(employee_id, 2) = 1 AND name NOT LIKE 'M%' THEN salary
      ELSE 0
  END) AS bonus
FROM Employees
ORDER BY employee_id;
