I could not think of a better way other than using examples.

(1) Using this stmt, we can pick a number like 103103 which is divisible by 7. Pick another number satisfying the condition. Eg: 218218 divisible by 7 again. 116116 divisible by 7 again !!!

I tried all numbers and everything seems to work. So SUFF.

(2). 777777 divisible by 7 but 999999 is not divisible by 7. Hence ISUFF.

I would go with A as the answer. What is the OA????
