Question

this
1221 is a polyndrome number, which on reversing their digits gives
the same number. Thus, every polyndrome number with even number
of digits, is always divisible by 11.
Write a polyndrome number of 6 digits and verify whether it is
divisible by 11 or not?​

Answer 1

Answer:

D is the correct answer

Answer 2

Answer:

11: that's obviously divisible by 11. ... If this is the case, not only is our six-digit palindrome divisible by 11, but every even digit palindrome is, since we will be able to convert, as above, all even digit palindromes into a sum of terms, such that each term is a multiple of a number of the form 100
