Clues 1 and 19 tell us that Julian is 34 and in the 5th position. Also, by clues 15 and 18, he must be wearing a yellow tie. 2. Clues 5 and 16 tell us that Michael is the boss of R&D and in the 1st position. 3. Clues 11 and 12 tell us that the 40-year-old and 46-year-old bosses are both to the left of the HR boss, who in turn is to the left of Thomas. So Thomas must be in the 4th or 5th positions. But we know Michael is in the 5th, so (also using clues 8 and 14): • Thomas is in the 4th position and going on holiday in August; • the HR boss is in the 3rd position; • the Sales boss is 40 and in the 2nd position; • the 46-year-old boss is in the 1st position. 4. Clue 20 tells us the Marketing boss isn't at the 5th position, so by elimination of departments and ages, and using also clues 4 and 17: • the Marketing boss is 51, makes \$2000 monthly, and is at the 4th position;

• the IT boss is at the 5th position;

• the 55-year-old boss is wearing a blue tie and is in the 3rd position.

5. Clue 3 tells us the man with the black tie isn't at the end and is to the left of Adam, so by elimination of names and using also clues 9 and 13:

• Adam is in the 3rd position;

• Nathan has a black tie, earns \$4000 monthly, goes on holiday in December, and is in the 2nd position; • the boss who earns \$3000 monthly is in the 1st position.

6. Now the boss with the red tie must be in the 1st or 4th positions, and clue 2 tells us which:

• the boss with the red tie goes on holiday in June and is in the 1st position;

• the boss with the green tie is in the 4th position.

7. Finally, by clues 6 and 10 and then elimination:

• the boss in the 5th position makes \$5000 monthly and goes on holiday in March; • the boss in the 3rd position makes \$6000 monthly and goes on holiday in January.
