Answer 1

Answer:

any number whose sum of digits is divisible by 3 that number is divisible by 3 so 9 + 5 + 4 is equal to 18 so first number is divisible by 3

9 + 9 + 4 + 0 is equal to 22 which is not divisible by 3 so 9940 is not divisible by 3

3 + 0 + 4 + 5 is equals to 12 so 12 is divisible by 3 then 3045 is also divisible by 3

7 + 9 + 3 + 0 is equal to 19 as 19 is not divisible by 3 so 7930 is not divisible by 3
