At first, it may seem like there are an overwhelming number

02:12
of possible scoring systems,
42
132295
1793
02:14
so let's see if we can narrow our options.
43
134130
2627
그럼 선택지λ₯Ό 쀄일 수 μžˆλŠ”μ§€ μ‚΄νŽ΄λ³΄κ² μŠ΅λ‹ˆλ‹€.
02:16
We can start by looking for clues in the total scores.
44
136966
3587
λ¨Όμ € μ΄μ μ—μ„œ λ‹¨μ„œλ₯Ό 찾을 수 μžˆμŠ΅λ‹ˆλ‹€.
02:20
Every event was scored the same way,
45
140678
2419
λͺ¨λ“  μ‹œν•©μ€ λ™μΌν•œ λ°©μ‹μœΌλ‘œ μ±„μ λ˜μ—ˆκΈ° 떄문에
02:23
so the sum of all points in the entire tournament
46
143097
2669
전체 ν† λ„ˆλ¨ΌνŠΈμ˜ μ΅œμ’… 점수 ν•©κ³„λŠ” ν•œ μ‹œν•© 총점의 λ°°μˆ˜κ°€ λ˜μ–΄μ•Ό ν•©λ‹ˆλ‹€.
02:25
must be a multiple of one event’s total.
47
145808
2961
02:29
In other words, if there were three events that scored 3, 2, 1,
48
149020
4254
즉, 3점, 2점, 1점으둜 λ°°μ λ˜λŠ” μ‹œν•©μ΄ μ„Έ 번 μΉ˜λŸ¬μ‘Œλ‹€λ©΄
02:33
which adds up to 6, the total points for the day would be 18,
49
153274
4504
ν•œ μ‹œν•©λ‹Ή 총점은 6점이 되고, κ·Έλ‚ μ˜ 점수 ν•©κ³„λŠ” 18점이 λ˜λŠ” κ±°μ£ .
02:37
which is three events times 6 points.
50
157862
2627
즉, 6점에 μ‹œν•©μ˜ 갯수인 3λ²ˆμ„ κ³±ν•œ 값인 κ²ƒμž…λ‹ˆλ‹€.
02:40
Our total is 40.
51
160531
1585
이번 κ²½μš°μ—” 총점이 40점이죠.
02:42
So we can make a table of possibilities: one event totaling 40 points,
52
162241
5047
λ”°λΌμ„œ λ‚˜μ˜¬λ§Œν•œ μ μˆ˜ν‘œλ₯Ό λ§Œλ“€ 수 있죠.
μ‹œν•©μ΄ ν•œ 번이면 총점은 40점,
02:47
two totaling 20, four totaling 10, and so on.
53
167413
3962
두 번이라면 μ‹œν•© λ‹Ή 20점,
λ„€ 번이라면 μ‹œν•© λ‹Ή 10점. 이런 μ‹μœΌλ‘œμš”.
02:51
We know there were at least three events, which eliminates these options,
54
171751
4296
μ‹œν•©μ΄ μ„Έ 번 이상 μΉ˜λŸ¬μ§„ κ±Έ μ•„λ‹ˆκΉŒ, 이런 μ„ νƒμ§€λŠ” μ œκ±°ν•  수 있겠죠.
02:56
and we can also get rid of events with fewer than 6 points,
55
176172
3253
μ‹œν•© λ‹Ή 총점이 6점 미만인 선택지도 μ œκ±°ν•  수 μžˆμŠ΅λ‹ˆλ‹€.
02:59
because the smallest possible total is 3 plus 2 plus 1.
56
179467
3754
μ–‘μˆ˜λ₯Ό λ”ν–ˆμ„ λ•Œ 제일 μž‘μ€ 값이 3+2+1이기 λ•Œλ¬Έμ΄μ—μš”.
03:03
That leaves two prospects.
57
183387
2044
그러면 μ •λ‹΅ 후보가 2κ°œμž…λ‹ˆλ‹€.
03:05
Let’s try to narrow those further by breaking down the possible points
58
185556
4046
λ²”μœ„λ₯Ό μ’€ 더 μ’ν˜€ λ΄…μ‹œλ‹€.

03:09
earned in each event:
59
189602
1501
03:11
if first place received 7 points,
60
191270
2544
λ§Œμ•½ 1등이 7점을 λ°›λŠ”λ‹€λ©΄
03:13
the teams that had totals of 9 couldn’t have won an event
61
193981
3337
총점 9점을 λ”΄ μ°Έκ°€μžλŠ” μ ˆλŒ€ 1등을 ν•œ 적이 없을 κ²λ‹ˆλ‹€.
03:17
because their total score would be 10 or more.
62
197318
2586
μ™œλƒν•˜λ©΄ ν•œλ²ˆμ΄λΌλ„ 1등을 ν•˜λ©΄ μ΅œμ’… 총점은 적어도 10점을 λ„˜κ±°λ“ μš”.
03:20
That means the team with 22 would have to have won all four.
63
200029
4087
즉, 22점을 νšλ“ν•œ μ°Έκ°€μžκ°€ μ‹œν•© λ„€ 개λ₯Ό μ „λΆ€ 이겼어야 ν•œλ‹¨ κ±°μ˜ˆμš”.
03:24
But then their total would be 28, so we can eliminate that option.
64
204200
3587
ν•˜μ§€λ§Œ κ·Έλ ‡λ‹€λ©΄ 총점이 28점이 되죠. κ·ΈλŸ¬λ―€λ‘œ 이 μ„ νƒμ§€λŠ” 없앨 수 μžˆμŠ΅λ‹ˆλ‹€.
03:28
And with four events, these numbers can't be made to add up to 22.
65
208079
4337
μ‹œν•©μ΄ λ„€ 번인 경우 이 μ μˆ˜λ“€μ„ μ–΄λ–»κ²Œ 더해도 22λ₯Ό λ§Œλ“€ 수 μ—†μ–΄μš”.
03:32
Finally, if first place got 5 points,
66
212667
2961
λ§ˆμ§€λ§‰μœΌλ‘œ, 1등이 5점을 μ–»λŠ”λ‹€λ©΄
03:35
the highest possible score with four events would be 20,
67
215628
3629
λ„€ 번의 μ‹œν•©μœΌλ‘œ 얻을 수 μžˆλŠ” κ°€μž₯ 높은 총점은 20이 되기 떄문에
03:39
getting rid of these two as well.
68
219298
2127
이 두 가지 선택지도 없앨 수 μžˆμ–΄μš”.
03:41
In fact, five events scoring 4 each could only reach 20 as well.
69
221634
4963
μ—­μ‹œ, λ‹€μ„― 번의 μ‹œν•©μ—μ„œ λͺ¨λ‘ 4점을 득점해도 총 20점에 그치죠.
03:46
That leaves us with just one possibility:
70
226722
2586
결과적으둜 μ •λ‹΅ ν›„λ³΄λŠ” 단 ν•˜λ‚˜λ§Œ λ‚¨μŠ΅λ‹ˆλ‹€.

There’s exactly one way to make those scores add up to 22:
