-4
Nine. The sum of the digits must be a multiple of 9; because of the repeated digits, this is only possible if the first two digits add up to 9.
There are 10 palindromes divisible by 9 between 1000 and 9999.
there are 90 palindromes in 100 to 1000 As; 10 palindromes in each 100 and upto 1000, there are 9 hundreds.Therefore; 9 into 10 is equal to 90
An infinite number.
9 of them.
There are infinitely many multiples of 9 and it is not possible to add them all.
think I suppost to know.
There are 9,000 palindromes between 10,000 and 99,999. A five-digit palindrome takes the form (abcba), where (a) can range from 1 to 9 (9 options), and (b) and (c) can each range from 0 to 9 (10 options each). Thus, the total number of five-digit palindromes is (9 \times 10 \times 10 = 9000).
They are the infinitely many multiples of 990.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
9 multiples
Infinitely many.
