i'm a 3 digit number i have no even numbers , the difference of my hundreds and ones digit is 0 the sum of digits is a prime number I'm equidistant from two prime numbers I'm less than five hundred

Answer 1

The number is 111.

1) hundred's digit - one's digit = 1 - 1 = 0

2) 111 is equally far away from 109 and 113 (both are prime numbers)

3) 111 is less than 500

Hope this helps!
