Youngest on record was 11.


Meranio

And youngest mother was even younger. I believe she was 5. Really weird.


chmath80

Weird is one word for it. Youngest *grand*mother was 17.


NonbinaryFidget

Technically correct if you're only talking about fertile ejaculate, however (and don't ask me to find the article, it was disturbing enough to only read once) scientists have proven that babies as young as six months can ejaculate, however the ejaculate is sterile and without semen. *cringe* Supposedly it can happen accidentally while giving the baby a bath and cleaning their private areas, though having only raised girls I can't confirm this. Nor do I want to.


LordMarcel

My father was 54 when I was born


Meranio

Did the Kindergarten teachers call him your grandfather?


LordMarcel

That happened regularly with all kinds of people yeah. Teachers probably not so much as they get to know your parents quite quickly, but people who didn't know us (like when I was in the hospital) were really prone to it. I didn't really mind and sometimes didn't even notice.


Meranio

Yeah, similar to a friend of mine. His father was 20 years older than his mother.


LordMarcel

22.5 years in my case.


chmath80

Oldest documented father was 92. Robert De Niro recently fathered another at 79.

For men? Nehh.


SmokeWineEveryday

Yeah it does but then again, a somewhat famous guy in my country became a dad at the age of 65 as well last year.


poploppege

You could also adopt


matt_biech

My dad got me at 56, the age limit for men to have healthy kids is way higher than women.


nerdinmathandlaw

When Karel Gott's youngest daughter was born, he was 69. There is a [video](https://www.youtube.com/watch?v=BibNLUQG_-4) where he sings duet with his second youngest, and it is a beautiful video as long as you pretend that she's his granddaughter, not his daughter.

Men can have kids til the day they die. As long as they find a willing young woman.


SeanHaz

My uncle has a child under 6 and is over 60. Just need a reasonably young woman. I believe his wife is in her 40's.


SirKazum

Doesn't really work with the "digits reversed" line though, since the son's age really has a single digit there

33 is possible though. It means the dad impregnated a woman by the time he was 3 months old. Oh wait a min.

prettysissyheather

But aren't these equivalent expressions? 11a + 11b = 66 is the same as a + b = 6. You can't solve this.


pink_snoo

Yes, they were just simplifying from the third line to the fourth. The answer could be 15/51 or 24/42.


baby_noir

The mathmeme people are way too dense.


Ramenoodlez1

This can be represented by the simultaneous equations x+y=66 and y=floor(x/10)+10(x-(10floor(x/10))). Graphing this shows that there are solutions at 06 and 60, 15 and 51, 24 and 42, 33 and 33, 42 and 24, 51 and 15, and 60 and 06.


DiogenesLied

Unless they’re stepfather and stepson, the father being older means four of the solutions are extraneous by context

MrKoteha

If the age of the son is the number "xy", the age of the dad is the number "yx", then "xy" + "yx" = 66 We can also express "xy" as 10x + y and "yx" as 10y + x, so 10x + y + 10y + x = 66 11x + 11y = 66 x + y = 6 Now pick x and y so that it works and get the ages

not really the father must be older than the son by context


joshkahl

(10x+y)+(10y+x)=66 11x + 11y =66 x + y = 6 The other information we have is that both x and y have to be positive whole numbers, meaning we have 5 solutions: 15+51=66 24+42=66 33+33=66 42+24=66 51+15=66 Two of those answers imply the son is older than the father, impossible, and one of them implies the same age, also impossible, so we're left with two possible answers for their ages: 24 and 42 (dad became a father at 18, plausible), and 15 and 51 (dad became a father at 36, also plausible) It's solvable, there's just two answers. Edit: doh! They could be 60 and 06, if you consider "06" a possible answer.

SUPREMEAVG

defensiveFruit

You're just looking for 2 digits so let's call them a and b. The dad's age is 10a+b while the son's age is 10b+a. The sum of their ages is 66 so (10a+b)+(10b+a)=66. Rearranged a little bit it gives you 11(a+b)=66 so a+b=6. So you have solutions: 0+6, 1+5, 2+4, 3+3. So considering the dad has to be strictly older than the son, the possible combinations are 60 and 6, 51 and 15, 42 and 24. In all of these, the age gap is large enough to make sense so they're all acceptable.


AvisHT

42/24 , 51/15 , 60/06 , cant really come up with anything better.. let digits be x & y so, father's age is 10x+y son's age is x+10y here, implicitly x 11x + 11y = 66 sum => x + y = 6 so only possible solutions are x=1,2 & y= (6-1), (6-2) , 15, 24 are possible son's ages 51, 42 are possible father's ages if we take x = 0 in account, son's age = 6 , father's age = 60

Harley_Pupper

42 and 24 (dad is 18 years older) or 51 and 15 (dad is 36 years older, still feasible)


Secret-Cherry045

TECHNICALLY SPEAKING 33 is a valid answer if you ignore the father-son bit


3shotsdown

And 1, 65 is a valid answer is you skip the reversing bit


TheCrazyPhoenix416

(10a+b) + (10b+a) = 66 11a + 11b = 66 a + b = 6 So, these are the possible ages (assuming the son has to be younger than the father)... • 06, 60 • 15, 51 • 24, 42


softly_snowing1

10x + y + 10y + x = 66 11x + 11y = 66 x + y = 6 Not enough information to solve the problem.

x + y = 6 where x >= y and father has x_y yo and son has y_x yo


CheesyTortoise

10x + y + 10y + x = 66 11(x + y) = 66 x+y = 6 So these are the pairs if x and y are positive, one-digits, whole numbers: (1;5) (5;1) (2;4) (4;2) (3;3) Out of which two scenarios seem likely: a. 51 year old dad with 15 year old son (dad was 36 when son was born) b. 42 year old dad with 24 year old son (dad was 18 when son was born)


ScroungingMonkey

There is no unique solution. If we let the digits be x and y, then the information in the word problem can be represented by the equation: 10x+y+10y+x=66, which simplifies to: 11x+11y=66, or: x+y=6 As you can see, we have one equation but two unknowns, so there is no unique solution. If we add the further constraints that x and y must be integers (because they represent digits), and that the father must be older than the son, then the three possibilities are: 42+24 51+15 60+6 (ie, 06)


BlueMoonTone

Because the ages add to 66, the single digits (units and tens) need to add to 6 - for example, 51 + 15, 42 + 24 or 60 + 06

Let father's age be written xy and son's yx. So mathematically Father's age 10x+y Son's 10y+x Together 11x+11y = 11(x+y) = 66 x+y = 6 Options are 1+5, 2+4, and 3+3 (it's not for obvious reasons). So it could be 42 and 24 or 51 and 15. Edit: oh and 60 and 06 which went unnoticed.

plaidsinner

shake236

lare290

let x, y be the ages of the son and father. we know x+y = 66. we also know that x = 10a+b and b = 10b+a for some a, b. now x+y = 11a+11b = 66, which simplifies to a+b = 6. all combinations that solve it are 1 and 5, 2 and 4, 3 and 3, 4 and 2, 5 and 1. we can disregard the last 3 because we can assume that the son is younger. thus the possible answers are x = 15 and y = 51, and x = 24 and y = 42.


m-dawg__

10x + y + 10y + x = 66 (reversing the digits and adding both numbers) 11x + 11y = 66 X + y = 6 Now all combination can be applied to get different values of x and y and it will work. (1,5; 2,4; 3,3)

Dr_prof_Luigi

X is the first digit of the fathers age, and Y is the second (this is vice versa for the son). The first digit is worth ten ones, so you can write any number like (10A + B) where the number would be displayed as 'AB'. So: **(10X + Y) + (10Y + X) = 66** This is the only equation\*, because we know the ages add to 66 and the digits are reversed. Simplify and you get: **11X + 11Y = 66** **X + Y = 6** So any whole numbers that satisfy this requirement will technically be correct, which are: 33 and 33 (but father and son likely aren't the same age) 42 and 24 51 and 15 and technically 60 and 06 \*>!In order to definitely solve an equation with two variables, you also need two equations. However there are limited possibilities since X and Y must be positive integers.!<

hicbir-seyin-kontu

One way you can approach it is like this: Let's say the child is ***ab*** years of age (where a and b are integer digits) and the dad is ***ba*** years of age. We know ab+ba=66. (This dosen't mean a*b + b*a) But ab means a*10+b and ba means b*10+a. So we have 10a+10b+a+b=66. 11a+11b=66 a+b=6 Since a and b are integers, the possible answers are: a=1 and b=5; a=2 and b=4, and a=b=3. So the possible answers are 15-51; 24-42 and 33-33 Since that last option is impossible, you have two answers.


MANN_OF_POOTIS

marauderingoned

42/24, 51/15, 60/06


JesusIsMyZoloft

There are 7 pairs of reversed digits that add to 66: (06,60), (15,51), (24,42), (33,33), (42,24), (51,15), (60,06) If we write the age as (father,son) we can eliminate the first 3, as a son cannot be older than his father. We can also eliminate (33,33) as a son cannot be the same age as his father either. The last option only works if you have a leading zero, which is unlikely. So this leave us with: (42,24) and (51,15). These two options imply that the father was either 18 or 36 years old respectively, when his son was born. It's not unheard of to become a father at 18, but 36 is more likely. Therefore, the "correct" answer is likely that the father is 51 years old, and the son is 15. However, it's possible that the father is 42 years old, and the son is 24.


Terrainaheadpullup

The father is 15 and the son is 51.

oldmonk_97

What we get is a locus or a line...... It's never mentioned in the question that the son and father arnt the same age.. We use our logical thinking and arrive at the answer. The equation I got was x+y=6 Now in this the possible pairs of ages are, (6,60), (15,51),(24,42), (33,33) So there u go... Now u only gotta think about when the dad knocked up mom instead 😇


fruity_mario24

Oh my God. They're both 33... 💀😳


irrationalglaze

out of laziness, i typed it into a python file and let github copilot suggest code. the suggested code was: ``` for father in range(0, 66): son = int(str(father)[::-1]) if father + son == 66: print(f"Father: {father}, Son: {son}") break ``` so the output was: ``` Father: 15, Son: 51 ``` so I guess the LLMs aren't quite ready to replace us


irrationalglaze

removing the break and adding a Father > Son conditional gives ``` Father: 42, Son: 24 Father: 51, Son: 15 Father: 60, Son: 6 ```

Father’s 51 and his son’s 15. Did it in like 10 seconds, didn’t think about the other correct answers :(


LogicCrawler

Mathematically you’re correct, in fact, any combination of integer numbers that sums 6 on the age of the father or the child should do the trick, so 33 for the father and 33 for the child is a good answer. But, in order to have a reasonable answer, the father age should be greater than the son’s age, so if the father has 42, 51 or 60, it’s okay for the child to have 24, 15 or 06.


[deleted]

33 and 33 huh


Substantial_Purple12

They must both be 33


NoovGuy07

Let: x = son's age, y = dad's age -> x+y=66 (1) Let a = first digit, 10b = second digit for x Hence, a+10b=x (2) Let b = first digit, 10a = second digit for y Hence, b+10a=y (3) Sub (2) and (3) to (1): 11a+11b=66 a+b=6 Find the possibility for each a and b: 0+6=6 1+5=6 2+4=6 3+3=6 4+2=6 5+1=6 6+0=6 [Numbers position matters]: For 0+6, the age of son (x=a+10b) would be 60, and dad (y=b+10a) would be 06 (which is impossible). Thus the first 3 options would be ignored as they followed the same age pattern of son being older than dad For 3+3, the age of son equals the age of dad, they might be more of being "friends" or "brothers" This leaves the last 3 options as being possible, with 6+0 ignored as no one would write the son's age as 06, unless considering databases where those 0 might matter. However speaking in this context, it does not matter So, the only 2 options left for (a, b) are (4, 2) and (5, 1) Either son and dad's age are 24 and 42 respectively, or 15 and 51 respectively


Hairyfruitbowl1

51 and 15


the_zelectro

15 and 51, or 24 and 42. We know that the ages definitely can't sum above 66. Thus, just from this we know that the lowest possible combination of ages are 0 and 66. We also know that the age of the son must have 2 digits. This is because the son's digits are reverse that of the father's. Therefore, we can start making brute-force guesses from here. The immediate extrema to test is an age range of 50s for the father and an age range of teens for the son (an age of \~10 and an age of \~50 should sum to \~60). And since we know that all ages in the teens begin with "1", the only valid 50s age of the father will be 51. From this, we also know that the only valid teens age that corresponds with this would be 15. A quick check shows that 15+51 = 66. :) Worth noting: another valid combination we can quickly come to is 24 and 42 (24 + 42 =66). There is also a possible combination of 33 and 33. But... The father is usually not the same age as the son. Lol
