Well, you're in a real pickle.

Xo’sh, sen juda mushkul muammodasan.
00:08
You see, a few years ago, the king decided your life would be forfeit
1

3754
Agar qirol xazinasini ko’paytirmasang
00:12
unless you tripled the gold coins in his treasury.
2

3003
qirol seni o’lishingni qaror qilgan.
00:15
Fortunately for you, a strange little man appeared
3
15845
3128
Baxtga ko’ra, gnom paydo bo’lgan,
00:18
and magically performed the feat.
4
18973
1919
va buni sehr yordamida amalga oshirgan.
U sehrli xalta ichiga tillalar soldi,
00:21
He placed handfuls of coins in and out of a magical bag,
5
21184
4045
00:25
and sang a strange rhyme:
6
25229
2253
va g’alati bir qo’shiq kuyladi: aminmanki
00:28
“The more gold goes in and more comes out, as sure as I am me.
7
28024
4671
“Qancha ko’p tilla, shuncha ko’p tilla.
00:32
And in again, and out again, and now it’s it times three!”
8
32862
4504
Kirib, chiqib tillalar, mana 3 barobar!”
00:38
Incredibly, that tripled the coins and saved your life.
9
38242
3045
Ajablanarlisi, u hayotingni asrab qoldi.
00:41
Were you grateful? Yes. Were you desperate? Yes.
10
41287
4046
Xursandmisan? Ha. Muhtojmiding? Ha.
00:45
Did you promise him your first-born child in exchange for his help? Yes.

Evaziga birinchi bolangni va’da berding.
00:51
Fast forward to today.
12

1543
Hozirga kelsak.
00:52
No sooner have you given birth to a beautiful baby boy
13
52757
3503
Go’dakni dunyoga keltirishing bilan,
00:56
than the little man shows up to claim his prize.
14
56260
3128
Gnom sovg’ani olish uchun paydo bo’ldi.
00:59
You cry and beg him not to take the baby.
15
59514
2877
Yig’lab undan bolani olmasligini so’rading
01:02
Softening, he begins, “If you can guess my name—”
16
62642
3920
Ohista, “agar ismimni aytsang__”
01:06
“Banach-Tarski?” you say. “It’s on the front of your shirt.”
17
66896
3545
“Banak-Tarski”. “U kiyimingda turibdi.”
01:11
“What! That won’t do. Aha. My bag,” he explains,
18
71651
5255
“Nima! Bo’lishi mumkinmas. Qopim,” dedi u,
01:16
“increases the number of gold coins placed inside it in a very special way.
19
76906
5505
ichidagi tillalarni noodatiy ko’paytiradi.
01:23
If I take any number of coins and place them in, more will come out.
20
83246
5130
Solgan tillalaring ko’proq bo’lib chiqadi.
01:28
And if I place those in the bag again,
21
88376
3420
Va agar ularni yana solsam, umumiy soni
01:31
the total that comes out will be three times whatever I began with.”
22
91796
4629
boshida solganimdan 3 martaga ko’payadi.
01:37
He takes 13 coins and places them in the bag,
23
97009
3629
U 13 ta tillani qopga soladi. Va
01:40
then removes the contents.
24
100638
2211
chiqqanini oladi. Va u deydi,
01:42
“I’ve used the magic once, not twice,” he says.
25
102890
3379
“Men 1 marta sehr qildim, 2 marta emas.”
01:46
“Tell me how many coins are in my hand and I’ll have mercy.”
26
106269
4462
“Nechta tillam bor va men shafqat qilaman”
01:51
How many coins is he holding?
27
111190
2503
Unda nechta tilla bor?
01:53
Pause here to figure it out yourself. Answer in 3
28
113693
3545
Shu joyda to’xtab, nechtaligini ayting. 3
01:57
Answer in 2

01:58
Answer in 1
30

1
02:00
The bag’s magic works just like what in mathematics is called a “function,”
31
120116
4546
Qop sehri xuddi “funksiya” tushunchasidek,
02:04
and it’s convenient in both cases to use an arrow to denote the transformation.
32
124662
4880
Ko’payishni ko’rsatgich orqali belgilaymiz
02:10
We can write what we know like this.
33
130376
2211
Bilganimizni shunday yozsak bo’ladi.
02:13
We want to know what goes in this particular blank.
34
133045
3170
Bosh joyga nima kerakligini bilib olamiz.
02:16
Maybe the bag just multiplies the number of coins by some number.
35
136674
3504
Qop tillalarni qaysidir songa ko’paytirar.
02:20
In that case, multiplying by that number twice
36
140178
3128
Bunda, o’sha songa 2 marta ko’paytirish
02:23
would be the same as multiplying by 3,
37
143306
2294
xuddi 3ga ko’paytirishdek bo’ladi,
02:25
which means the multiplier would be the square root of 3.
38
145600
3378
ya’ni ko’paytiruvchi 3ning ildizi bo’ladi.
02:29
That’s not a whole number, though.
39
149187
1626
Ammo, bu butun son emas. Va tillalar
02:30
And we don’t have bits of gold coins coming out of the bag.
40
150813
2961
bo’laklarga bo’linib qopdan chiqmayapti.
02:34
Something else is going on.
41
154025
2085
Yana nimadir sodir bo’lyapti. Xo’sh, agar
02:37
Well, if filling in the blank between 13 and 39 is too hard,
42
157236
5089
bo’sh joyni 13 bilan 39 orasida to’ldirish
02:42
maybe we can start with something easier.
43
162325
2335
qiyin bo’lsa, boshqa osonroq yo’l tutamiz.
02:44
Can we figure out what’ll happen to 1 coin?
44
164660
3254
1 ta tillaga nima bo’lishini bilasizmi?
02:48
If you use the bag on a single coin twice, you end up with triple;
45
168456
4713
Agar 1 ta tillani 2 martda solsez, 3 ta
02:53
that’s three gold pieces.
46
173169
1960
bo’ladi: bu 3 tillalar degani. Chunki
02:55
Because the bag always increases the number of gold coins,
47
175880
4004
qop tillarni sonini doim oshiradi, bo’sh
02:59
the blank must be between 1 and 3, so 2.
48
179884
3795
joydagi son 1 va 3 orasida, shu uchun 2.
03:03
It’s a start. What’s next?
49
183679
2044
Bu boshlanishi. Keyinchi?
03:05
Let’s think about a few other possible starting places.
50
185723
3504
Qani boshqa boshlanish joylarini o’ylaymiz
03:09
We already know 2 becomes 3
51
189352
2294
Allaqachon bilamizki, 2 soni 3ga aylanadi
03:12
and that lets us fill in the next blank as well.
52
192021
3337
va bu keyingi bo’shliqni to’ldiradi.
03:15
Now we’re getting somewhere!
53
195566
1919
Mana endi, javoblarni topyapmiz.
03:17
We just need to extend this out to 13.
54
197485
3086
Buni shunchaki 13gacha cho’zishimiz kerak.
03:20
Remember the other rule, though:
55
200863
1835
Ammo, qoida yodda tursin:
03:22
when you put more coins in, you get more coins out.
56
202698
3170
ko’proq tilla solsang, ko’proq olasan.
03:26
That means the numbers in every column must go in increasing order as well.
57
206327
5797
Bu degani, har ustundagi son o’sishi kerak
03:32
In other words, because 6 coins become 9,
58
212375
3336
Ya’ni, chunki 6 ta tilla 9 ta bo’ladi,
03:35
it’s not possible for 4 coins to become 10.
59
215711
3462
4 ta tilla 10 ta bo’lishi mumkinmas.
03:39
Nor could 4 become 5, since 3 becomes 6.
60
219173
4463
4 5 bo’la olmaydi, chunki 3 6 bo’ladi.
03:43
So 7 and 8 fill those blanks on the right of 4 and 5,
61
223761
4963
Demak, 7 va 8, 4 va 5 ning yonida bo’ladi,
03:48
which in turn gives the answer for two more blanks.
62
228891
3337
bu boshqa 2 ta bosh joyga sonlar beradi.
03:52
Knowing that the numbers go in increasing order in every column,
63
232937
4421
Hamma son o’sishini hisobga olgan holda,
03:57
the only choices for the remaining blanks are 19, 20, 22, and 23.
64
237358
6423
19, 20, 22, va 23 javob sifatida qolyapti.
04:04
And look! We have our answer!
65
244031
2002
Va qara! Javoblar tayyor!
04:06
There must be 22 gold coins in his hand.
66
246284
3378
Uning qo’lida 22 ta tilla bo’lishi kerak.
04:09
“I’ll give you three guesses,” the little man begins to say.
67
249954
3128
“3ta imkon beraman,” dedi gnom.
04:13
“22 coins,” you respond.
68
253082
1793
“22 ta” deding.
04:14
“What?! How did you know?”
69
254875
1544
“Nima? Qanday bilding?”
04:16
“I enjoy a good riddle,” you say. “Also, it’s on the back of your shirt.”
70
256419
4671
“Topishmoq yoqdi. Javob kiyiming orqasida”
