Logic Problem Solution:
Pokeyman Card Swap
By clue 12, no two boys ended up simply exchanging cards. By clue 6,
four of the traders are Jamie, the Ruiz boy, and the ones who started
with and ended up with DragonEarth and Mynx. By clue 10, the boy who
finished with Change never had Mynx at all, so he isn't Jamie or Ruiz
and didn't have Mynx to start. If the one who acquired Change were
the fifth boy to the four in clue 6, then the boys who started with
DragonEarth and Mynx would have simply exchanged cards, since Jamie
and Ruiz did not finish with those two cards--but that contradicts
clue 12. So, the boy who ended up with Change started with DragonEarth.
Then the one who finished with Mynx would have to be the fifth trader
to the four in clue 6, and the boy who started with Mynx ended up with
DragonEarth. The boy who finished with Mynx didn't start with Change,
or Jamie and Ruiz would have simply exchanged cards. Therefore, since
the Carpenter boy got Ben's card through the trading (2) and since Ben
isn't Ruiz (4) and Carpenter isn't Jamie (9), Ben started with
DragonEarth or with Mynx. If Ben had started with Mynx and Carpenter
ended with that Pokeyman card, by clue 1, Damon would have traded away
DragonEarth and gotten Change. Then by clue 7, Holman would be
Ben--no (4). Therefore, Ben started the trading with DragonEarth and
acquired Change, while Carpenter got DragonEarth and gave away Mynx.
By clue 7, the Holman boy got Damon's double. Damon isn't Ruiz (1).
If he had gotten Mynx in the trading, Holman would have to be Jamie.
But there is no way for Westbrook to have gotten Berger's card (8) with
this arrangement. Damon is Carpenter, and the Holman boy went home
with Mynx. Ruiz got Prof. Pine or Burst of Energy and thus can't be
Thad (3), who is Holman; Ruiz is Michael. Since Westbrook ended up
with Berger's card (8), Ben must be Westbrook and Jamie Berger.
Jamie Berger did not get Prof. Pine (5), so Michael did; and Jamie
finished with Burst of Energy. Since Michael didn't have Change at
the beginning (11), he must have had Burst of Energy. By clue 12, finally,
Jamie started with Change and Thad Holman with Prof. Pine. The boys
therefore started with and ended up with Pokeyman cards as follows:
- Ben Westbrook, DragonEarth - Change
- Damon Carpenter, Mynx - DragonEarth
- Jamie Berger, Change - Burst of Energy
- Michael Ruiz, Burst of Energy - Prof. Pine
- Thad Holman, Prof. Pine - Mynx
