N is a duodecimal (base 12) positive integer having precisely 50 digits such that each of its digits is equal to 1 except the 26th digit. If N is divisible by the duodecimal number 17, then find the digit in the 26th place.
(In reply to analytical solution
Duodecimal digits are : 1,2,3,...9.,A,B.
BTW, I BELIEVE 11, i.e. B IS THE CORRECT SOLUTION-
but there is no need to solve it explicitly - see my solution.
