Question

If $43A2$ is divisible by $3$ the possible values of $A$ are

• A. $3,6,9,0$
• B. $1,4,7$
• C. $2,5,8$
• D. None of these.

Answer 1

The correct option is A $3,6,9,0$

The number is divisible by $3$ only if the sum of digits is divisble by $3$

$43A2$ is divisibel by 3 only if $4+3+A+2=9+A$ is divisible

So $⟹A=0,3,6,9$
