Question

45678x9231 is divisible by 3 , then how many values are possible for x

Answer 1

Answer:

the answer is 3, 6, 9 or 0.

Step-by-step explanation:

the divisibility test of 3 is that all the digits add up to a multiple of 3.

therefore in the number we add all the digits:

45678x923  => 4+5+6+7+8+9+2+3+x  is divisible by 3

                          9+13+15+14+x is divisible by 3

                          51+x is divisible by 3

as 51 is divisible by 3, x can be any single digit that is divisible by 3, which are 0, 3, 6, or 9.
