Official Solution:

Statements (1) and (2) by themselves are sufficient. S1 tells us that the last three digits of \(N\) are the same as the first three digits: \(N = abcabc\). Note that \(N = abc*1000 + abc = abc*1001\). As 1001 is divisible by 7, \(N\) is also divisible by 7.

Answer: D

Dear

BunuelHow do you prove statement 2 to be sufficient by itself?

As I understood, it simply says that all numbers are equal but where can I go from this info?

thanks
