Sum of odd-numbered digits ( - ) Sum of even-numbered digits or vice versa is divisible by 11

We have:

(2 + D + D) - (3 + 6 + 9) is divisible by 11

<=> 2 + 2D - 18 is divisible by 11

<=> 2D - 16 is divisible by 11

<=> 2 (D - 8) is divisible by 11

So Greatest common divisor (2 ; 11) = 1

=> D - 8 is divisible by 11

0 \(\le D\le9\)

=> D = 8

So The answer is : 386,892
