Hint
Where does Harvey sit?
Answer
Seat 1 Peter
Seat 2 Lia
Seat 3 Kenny
Seat 4 Jennie
Seat 5 Harvey
Seat 6 Joyce
Seat 7 Rick
Seat 8 Mark
Jennie is in Seat 4 and next to Harvey (Clue 6), so Harvey is in Seat 3 or Seat 5.
Harvey has a higher seat number than Jennie (Clue 1), so Harvey is in Seat 5.
Peter is across from Harvey (Clue 2), so is in Seat 1.
Peter is next to Lia (Clue 7), so Lia is in Seat 8 or Seat 2. But Lia is not in Seat 8 (Clue 3), therefore Lia is in Seat 2.
Lia is next to Kenny (Clue 5), therefore Kenny must be in Seat 3.
Rick is across from Kenny (Clue 4), so must be in Seat 7.
Joyce is next to Rick (Clue 4), but not in Seat 8 (Clue 3), so Joyce must be in Seat 6.
The last remaining seat (Seat 8) is occupied by Mark (Clue 8).

Puzzle 192
A large fresh water reservoir has two types of drainage system: small pipes and large pipes.
6 large pipes, on their own, can drain the reservoir in 12 hours.
3 large pipes and 9 small pipes, at the same time, can drain the reservoir in 8 hours.
How long will 5 small pipes, on their own, take to drain the reservoir?

Hint
What would happen in 24 hours?
Answer
21 hours and 36 minutes.
Reasoning
In 12 hours: 6 large pipes can drain 1 reservoir.
In 24 hours: 6 large pipes can drain 2 reservoirs.
In 24 hours: 3 large pipes can drain 1 reservoir. [1]
In 8 hours: 3 large + 9 small pipes can drain 1 reservoir.
In 24 hours: 3 large + 9 small pipes can drain 3 reservoirs.
But, by [1] we know that in those 24 hours, 3 large pipes can drain 1 reservoir.
Therefore, the other 2 reservoirs can be drained by the small pipes on their own:
In 24 hours: 9 small pipes can drain 2 reservoirs.
(fix the number of hours, and divide pipes and reservoirs by 9)
In 24 hours: 1 small pipe can drain 2/9 reservoirs.
(fix the numbers of pipes, and multiply hours and reservoirs by 9)
In 216 hours: 1 small pipe can drain 2 reservoirs.
In 216 hours: 5 small pipes can drain 10 reservoirs.
Therefore, 5 small pipes can drain 10 reservoirs in 216 hours.
216 hours ÷ 10 = 21.6 hours.
21.6 hours = 21 hours and 36 minutes.
