Step-by-step explanation:

Answer 2

If a number is divisible by 3, then the sum of the digits is also divisible by 3.

Given, 3+2+0+x = 5 must be divisible by 3.

It can be possible when,

• x = 1 then 5+x = 6

therefore, the digit can be 3401

• x = 4 then 5+x = 9

therefore, the digit can 3404

• x = 7 then 5+x = 12

therefore, the digit can be 3407
