Correct answer
None of these
Why this answer is correct
A number is divisible by 6 only when the 6 is divisible by 2 and 3 where 2 and 3 are coprime numbers.
389 → 389 is not divisable by 2.
389 = 3 + 8 + 9 = 20 which is not divisable by 3.
471 → 471 is not divisable by 2.
471 = 4 + 7 + 1 = 12 which is divisible by 3.
379 → 379 is not divisable by 2.
379 = 3 + 7 + 9 = 19 which is not divisible by 3.
787 → 789 is not divisable by 2.
789 = 7 + 8 + 7 = 22 which is not divisible by 3.
Hence, No one number is divisible by 6.
