Mario Kart

Logic Level 3

Adam, Bob, Caleb, Dylan, Elaine, Francis, Gillian, and Hamilton all decided they wanted to play Mario Kart together. They played three races, and the winner was determined by a points system: ​

For getting first place in a single race, a player was awarded 8 points.​

For getting second place in a single race, a player was awarded 7 points.​

For getting third place in a single race, a player was awarded 6 points.​

For getting fourth place in a single race, a player was awarded 5 points.​

For getting fifth place in a single race, a player was awarded 4 points.​

For getting sixth place in a single race, a player was awarded 3 points.​

For getting seventh place in a single race, a player was awarded 2 points.​

For getting eighth place in a single race, a player was awarded 1 point.​

The First Race

Francis finished directly in front of Elaine, but finished directly behind Dylan.​

Bob was neither in first nor last, and did better than Adam.​

Gillian came in sixth place.​

Elaine did better than both Bob and Caleb, but did not do better than Hamilton.

​Dylan came in second.

Adam came in last.

The Second Race

Hamilton did better than Dylan (Dylan was not directly behind Hamilton), but was behind Bob (not directly).

Francis did better than both Bob and Elaine (in that order respectively).

Gillian did better than Dylan (Dylan was directly behind Gillian), but Gillian was directly behind Caleb.

Adam came in last.

The Third Race

Dylan and Francis finished fourth and fifth (but not necessarily in that order).

Caleb did better than both Elaine and Adam.

Gillian did better than Bob, but did worse than Caleb.

Elaine did better than Adam.

Dylan did worse than Caleb, but did better than Hamilton and Gillian.

Bob came in last.

Hamilton came directly behind Francis, and came directly in front of Gillian.

Based on the following information, figure out where everyone placed after three races. Each racer's first initial has a number assigned to it, and that is how the question is answered A=1 B=2 C=3 D=4 E=5 F=6 G=7 H=8, so someone's answer might look like, if they thought that Adam won: 1/////// (the / just represents the numbers that would go there). If there was a tie, put the initial that came first. I.e., if both Adam and Bob had 12 points at the end, then Adam's number would go first because the letter A comes before the letter B.


The answer is 56842317.

I don't know, but I still feel that the puzzle here is ambiguous. It could be 56842317 as the answer provided, but then, you can also have 65834217 or 56843271 as possible answers, too. I'm lucky that my second guess hit it.

EDIT (after the amendments)

For the FIRST RACE, Gillian's, Dylan's & Adam's placing were told to be 6th, 2nd and last respectively.
==> _ D _ _ _ G __ A

From first race's first clue, we get
==> _ D F E _ G __ A

From first race's second and fourth clues, we get B < A & H < E < { B , C }
==> H D F E _ G _ A ✓
{ B & C inconclusive } ✓

SECOND ROUND
B << H << D
F < { B , E }
C - G - D
Adam taking the rear .

==> B < E
==> F B E H C G D A ✓

THIRD & LAST RACE
{ D , F } = { 4 , 5 }
C < { E , A }
C < G < B
E < A
C < D < { H , G }
Bob taking the rear
F - H - G
==> C - E - A < D < F - H - G - B
==> C E A D F H G B ✓

Round 1st 2nd 3rd Total Ranking Notes
Adam 1 1 6 8 7th
Bob 2 @ 4 7 1 10 or 12 6th Inconclusive Round 1
Caleb 2 @ 4 4 8 14 or 16 4th or 3rd Inconclusive Round 1; C before H
Dylan 7 2 5 14 5th
Elaine 5 6 7 18 1st E before F
Francis 6 8 4 18 2nd E before F
Gillian 3 3 2 8 8th
Hamilton 8 5 3 16 3rd or 4th C before H

Conclusions : E F H C D B A G or E F C H D B A G

Answer : 56834217 56834217 or 56384217 56384217

I don't see how this puzzle could have more than one solution. Maybe I'm missing something here, but could you show me how this has more than one solution?

What I got for the first round is HDFEBG but inconclusive for the last two finishers A and C. Then a solid FBEHCGDA for the second round, but then I found the last leg of the journey to be the most confusing of all; B as the sure tail, of course, but all I got is {CEA} took the podiums, with E beating A, then the {DF} and {GH} pairs behind them, respectively.

I see. Thank you very much. I can now appropriately edit the question so the answer is more clear. Thanks for the help! As a side note, I had all of the racers and the places they came in in their respective races in notepad, but my brother accidently deleted the file :/

Maybe im wrong aswell, but i think the 3rd race has no unique solution. I found 65384271 to be a possible solution too

I fixed the 3rd race so it does have a unique solution, it's CEADFHGB

Now third is unique but the first is messy.

Actually no, even when you're answering the original question, C could never have beaten H. For H, it's between 15 or 16, and C ranged between 11 the lowest or 14 the highest.

No no i'm saying that C came in first for just the third race, not overall.

@Maxwell DiPillo Hi Max, sorry about the confusion, but I was replying to Eric for his final solution. I know that {CEA} set getting their 🏅 medals as long as E wins A.
