Here, the sum of the digits is 13. But 13 is not divisible by 3.

Conclusion: 733 is not divisible by 3.

(ii)10038

Here, the sum of the digits is 12 and it is divisible by 3.

Conclusion: 10038 is divisible by 3.

(iii)524781

Here, the sum of the digits is 27 which is divisible by 3.

Conclusion: 524781 is divisible by 3.

(iv)79124

Here, the sum of the digits is 23 which is not divisible by 3.

Conclusion: 79124 is not divisible by 3.

(v)20701

Here, the sum of the digits is 10 which is not divisible by 3.

Conclusion: 20701 is not divisible by 3.

(vi)872645

Here, the sum of the digits is 32 which is not divisible by 3.
