Question

If 2*739 is divisible by 3, which digit can be replaced in * place?

answer needed with explanation ​

Answer 1

Answer:

* =0,3,6 or 9.

Step-by-step explanation:

If a number is divisible by 3, the sum of its digits must be divisible by 3 also.

So, 2 + * + 7 + 3 + 9 is divisible by 3.

21 + * is divisible by 3.

If * = 0,3,6 or 9, the sum will be divisible by 3 and the number will be too.
