From your definition, a palindrome is a number that is the same whether read backwards or forward.

Also, a multiple of a number is a number that divides it without remainder.

Multiples of 3 that are three-digit are:

111
222
333
444
555
666
777
888
999
Those are the palindromes that are three digits and multiple of three. I got it by using calculator.

I hope I got it right.

To find the number of positive 3-digit palindromes that are multiples of 3, we can break this problem into a few steps:

Step 1: Identify 3-digit palindromes
A 3-digit palindrome is a number that reads the same forwards and backwards. These numbers have the form "ABA," where A and B are digits. A can be any digit from 1 to 9, and B can be any digit from 0 to 9. Since the middle digit B can be any digit, there are 10 choices for B (0 through 9). For A, there are 9 choices (1 through 9), as it cannot be 0 to maintain the 3-digit requirement. Therefore, there are a total of 9 * 10 = 90 different 3-digit palindromes.

Step 2: Determine which palindromes are multiples of 3
To check if a number is a multiple of 3, you can sum its digits. If the sum is divisible by 3, then the original number is also divisible by 3. So, for each 3-digit palindrome, calculate the sum of its digits and check if it's divisible by 3.

Step 3: Count the multiples of 3
Go through all the 3-digit palindromes and count how many of them are multiples of 3.

Now, let's perform these steps:

Step 1: There are 90 different 3-digit palindromes.

Step 2: Check which of these are multiples of 3. To do this, calculate the sum of the digits for each palindrome:

- For ABA palindromes:
- A = 1, B = 0: Sum = 1 + 0 + 1 = 2 (not divisible by 3)
- A = 1, B = 1: Sum = 1 + 1 + 1 = 3 (divisible by 3)
- ...
- A = 9, B = 9: Sum = 9 + 9 + 9 = 27 (divisible by 3)

So, out of the 90 different 3-digit palindromes, there are 10 that are multiples of 3.

Therefore, there are 10 positive 3-digit palindromes that are multiples of 3.

1. 111
2. 222
3. 333
4. 444
5. 555
6. 666
7. 777
8. 888
9. 999
10. 121

Palendromic are numbers spelt forward and backward same such as 'XYX"

For a 3 digit palendromic
The hundreds and units (first and last digit) must be the same which is from 1 through 9 = 9 possible outcome

The tens (middle number) runs from 0 to 9 = 10 possible outcome

Therfore
9 x 10 = 90
So it's 10 x 9 = 90 possible palendromic

Since it's a multiple of 3
Therefore 90 / 3 = 30

So we have a total of 30 palendromic which are divisible by 3

They are
111
141
171
222
252
282
303
333
363
393
414
444
474
525
555
585

WRONG
The other guy used free version of chatGPT, while you used the paid version.
[Still b]WRONG[/b]

jaeyking:


Oga I'm not wrong
And not all of us use ChatGpt for our answers

turmacs:

Are you a programmer?
Because in think you cheated.
Your working make no sense to me even though the answer is correct.

You must be a programmer

jaeyking:


My working won't make sense to you
If you are not maths oriented
Not all of use rely on got

I'm a mathematics teacher

When you say three digits
That's hundreds tens unit

....

Reminderz:


you dey actually expect that clown moniker to send 5K for you? you go explain tire

you should recognise things that ain't worth your energy, person wey dey ask clownish question sef fit nor get 5h for account... lmao

jaeyking:

I'm a mathematics teacher

When you say three digits
That's hundreds tens unit

The hundreds and unit (must run from 1 to 9) to be palendromic possible outcome of 9

Then the tens (middle number) must run from 0 to 9 possible outcome of 10

Some of us don't rely on ChatGpt and I doubt if u can even get the answer on it

It's a simple maths
U can do with a pen and paper

Even though when asked you will be asked to say just the number of possible palendromic

But I had to write out the possible 90 and pick the 30 multiples of 3

So should I drop the account number?

And if you need a tutor in maths I'm available too

Jennyclay:
I don’t know it

turmacs:

I knew somebody would go and ask chatGPT
Bro, i'm sorry but after all the copy and paste from chatGPT, no 5k for you because you are WRONG

A palindrome is a number that is the same when read forwards and backwards, such as 81218 , 414, 989, 12321, 141... and so on.
How many positive 3-digit palindromes are multiples of 3?
This is a problem that middle school students (equivalent to JSS in Nigeria) are supposed to be able to solve.

You must show your working, don't just come and drop answer.
First to solve it should drop he's or her account number

drop your account number

turmacs:
how will you know? to you even have a functional brain? not to talk of one that is capable of solving unembellished arithmetical problems.
Nonsense.

Jennyclay:
who is this one? .

You that have a functional brain why don’t you solve it Why bring it to nairaland for people to solve it for you

You that have a functional brain, your common sense didn’t tell you to post it on education section and not romance section

Biko, don’t let me start with you this evening.

turmacs:
And who told you i can't solve it? Mumu. If i can't solve it how did i know the answer? I'm not as dumb and brain dead as you, Idiot. Go and start with your ancestors not me because if you try me, i will make you commit suicide.
Nonsense

Leave talk send the guy e 5K...e deserve am!!

So you con believe dat empty head get any 5k to send anybody?

I just pity the poor guys wey just waste their time dey solve for who nor get Kobo wey never see food chop except one boy give am urgent 1500
