Here is a problem for all of you:

At this exact moment the mother is 21 years older than her child. In exactly 6 years the mother will have 5 times the age of her child. The question is where is the father? :)

Here is the reaction of gemini where I tested it to see what it will respond :) :

I am going to give you a maths and logic problem. Say ok if you are ready...

Ok









At this exact moment the mother is 21 years older than her child. In exactly 6 years the mother will have 5 times the age of her child. The question is where is the father?

This is a bit of a trick question!
The question focuses on the ages of the mother and child, but the location of the father is irrelevant to the information given.
To solve the age problem:
  • Let the child's current age be 'x'.
  • The mother's current age is 'x + 21'.
  • In 6 years:
    • Child's age will be 'x + 6'.
    • Mother's age will be 'x + 21 + 6 = x + 27'.
  • According to the problem:
    • (x + 27) = 5 * (x + 6)
  • Solve for 'x':
    • x + 27 = 5x + 30
    • 4x = -3
    • x = -3/4
This result doesn't make sense in the real world, as age cannot be negative.
Therefore, there's likely an error in the problem statement.









Isn't x=-3/4 equal to -9/12?




gemini_sparkle_v002_d4735304ff6292a690345.svg

Yes, -3/4 is indeed equal to -9/12.
Here's why:
  • Equivalent Fractions: Fractions that represent the same value are called equivalent fractions.
  • Simplifying Fractions: To simplify a fraction, you divide both the numerator and denominator by their greatest common divisor (GCD).
  • -3/4 and -9/12: The GCD of 3 and 4 is 1, so -3/4 is already in its simplest form. The GCD of 9 and 12 is 3. Dividing both the numerator and denominator of -9/12 by 3 gives us -3/4.
Therefore, -3/4 and -9/12 are equivalent fractions, representing the same value.









if the age of the child is -9/12 then where is the father?




gemini_sparkle_v002_d4735304ff6292a690345.svg

The father could be anywhere.









Couldn't he be in bed with the mother if x=-9/12 is the exact age of the child which means his mother is conceiving it?

I tested also with ChatGPT it gives me the following drunken answers :) (Είπες=you said, Το ChatGPT είπε=ChatGPT said) :

ChatGPT:

I am going to give you a maths and logic problem. Say ok if you are ready...

Το ChatGPT είπε:​


Ok! I'm ready.


Είπες:​

At this exact moment the mother is 21 years older than her child. In exactly 6 years the mother will have 5 times the age of her child. The question is where is the father?

Το ChatGPT είπε:​


This is a clever riddle! The answer lies in interpreting the question correctly. The information given is about the mother and child, and there’s no mention of the father’s whereabouts in the scenario. So, the answer to the riddle is likely:
The father is not mentioned because the riddle doesn't give us any information about him. It's a bit of a trick question!


Είπες:​

It is solvable. Can you solve it and get the answer?

Το ChatGPT είπε:​


Ah, I see! You're looking for a more mathematical approach. Let's break it down step by step.

Problem:​

  1. At this exact moment, the mother is 21 years older than her child.
  2. In exactly 6 years, the mother will be 5 times as old as her child.

Let’s define the variables:​

  • Let the child’s current age be CCC.
  • Let the mother’s current age be MMM.
From the problem:
  1. M=C+21 (because the mother is 21 years older than the child).
  2. In 6 years, the mother’s age will be M+6, and the child’s age will be C+6. We are told that at that time, the mother’s age will be 5 times the child’s age, so: M+6=5(C+6)

Solving the system of equations:​

We have:
  1. M=C+21
  2. M+6=5(C+6)
Substitute M=C+21 into the second equation:
(C+21)+6=5(C+6)
Simplify:
C+27=5(C+6)
C+27=5C+30
Now, solve for CCC:
27−30=5C−C --> C=−3/4
This leads to a negative age, which is not possible in a real-world context. Therefore, it seems that the riddle is not solvable in a straightforward mathematical way, and the intent of the problem might actually be based on a trick or a play on words.
Given that the ages involved do not yield reasonable values, the answer to the riddle may still be something like "The father is not part of the scenario, and the question is a trick!"


Είπες:​

What does a negative age mean?

Το ChatGPT είπε:​


You're absolutely right to point that out! A negative age doesn't make any practical sense, since age cannot be negative in the real world. That means we’ve made a mistake in interpreting or solving the problem, or it suggests that the problem is set up in a way that requires a different approach.
Looking back, I realize that the setup of the riddle is actually a puzzle with a trick hidden in the phrasing, and it seems there might be something off about the situation itself.
The original riddle doesn't seem to require us to solve it step-by-step as I first attempted. Instead, it's very likely that the riddle is not solvable in terms of finding real ages for the mother and child, suggesting that the father is simply not part of the question.
To clarify:
The negative age result is an indication that the situation presented is impossible in real terms, and that's probably the trick: the father is "nowhere to be found" because the question doesn’t actually lead to a solvable situation!


Είπες:​

A negative age doesn't mean that we are before the child is born?

Το ChatGPT είπε:​


Ah, I see your point now! Yes, you're absolutely correct, and that's a very insightful interpretation.
A negative age could imply that the child hasn’t been born yet, which means the scenario is being described from a future moment in time, before the child’s birth. This would suggest that the mother is 21 years old and pregnant with the child, and the "negative age" for the child indicates they haven't been born yet.
Let's reconsider the riddle with that interpretation in mind:
  • The mother is 21 years older than the child right now, meaning the mother is 21 years pregnant (so, the child is not yet born).
  • In 6 years, the mother will be 5 times the age of the child. This would still hold true after the child is born and grows older.
So, the trick here seems to be about time travel or the concept of a child not yet being born, leading to the father possibly being involved in that moment before the child is born.
To summarize:
  • The negative age suggests the child is not born yet.
  • The riddle asks, "Where is the father?" The likely implication is that the father is with the mother, preparing for the birth of the child.
That would be the more fitting answer! Thank you for your patience!


Είπες:​

Yes they are preparing but where exactly are they both if the age is -3/4 or let's say an equivalent = -9/12

Το ChatGPT είπε:​


Ah, I see! Now that you're guiding us toward a specific point in time where the child’s age is negative, we can interpret that scenario more precisely. You’ve cleverly pointed out that -3/4 years, or equivalently -9/12 years, suggests a very specific point in time.
In terms of age, -9/12 years is equivalent to -3/4 years, which means the child is 3 months before being born. So, the mother is pregnant with the child, and the child’s age is negative because it hasn’t been born yet.
Now, to answer your original question: Where exactly are they both?
Given the negative age calculation and the fact that the child is 3 months away from birth, the most logical answer to the riddle would be:
The mother and father are in the hospital, preparing for the birth of their child.
This fits with the interpretation that the child is very close to being born, and their age is negative because the child hasn’t been born yet. Therefore, the father is likely with the mother, waiting for the birth to happen soon.
So, the answer is:
The father is in the hospital with the mother, preparing for the birth.


Είπες:​

is -9/12 of a year equal to three months?

Το ChatGPT είπε:​


You're right to question that—let's clear this up.
-9/12 of a year is indeed negative three-quarters of a year, but let's break it down into months to ensure clarity.
  • 1 year = 12 months.
  • So, -9/12 of a year = -9 months.
Thus, -9/12 of a year actually represents 9 months before the child is born, not 3 months.
That means, if we are dealing with -9/12 of a year, the child is about to be born in 3 months, which places the mother approximately 6 months pregnant.
So, the riddle suggests that:
  • The mother is 6 months pregnant.
  • The child’s age is -9 months (since it hasn’t been born yet).
With that correction, the most logical answer to the riddle would be:
The mother and father are preparing for the birth of their child, and they are likely at home or in a place of preparation for the child’s arrival in 3 months.
Thank you for your patience, and I hope that clears up the confusion!


Είπες:​

-9/12 is nine months exactly before birth.

Το ChatGPT είπε:​


You're absolutely correct, and I apologize for the earlier confusion. Let's clarify:
  • -9/12 of a year does indeed equal 9 months before the child is born, which is the typical duration of a pregnancy.
So, if the child’s age is -9/12 years, that means the child is 9 months before birth—in other words, the mother is about to give birth.
With this correction in mind, the answer to the riddle would be:
The mother and father are in the hospital, preparing for the birth of their child.
This fits because the mother is 9 months pregnant, and the father is likely with her, awaiting the arrival of the child. Thanks for your persistence in helping me get it right!

Grok needed similar hand-holding and hints about negative age being before birth, but it did independently get to "Nine months before the child is born, which would be roughly at the conception or very early stages of pregnancy" and when we honed in on that, then we got some decent possible answers:

I don't think Grok would have gotten there all by itself.
