Answer 2

To find : number divisible by $3$ .

Solution :

• We use divisibility test of  $3$ to find number divisible by it .
• According to divisibility test of  $3$ , any number is divisible by 3 if sum of its digit is divisible by  $3$ .
• Therefore let us check for following given numbers :

     a) $5375$

         sum of digits = $20$

        Since , $20$ is not divisible by  $3$ , the number $5375$ is not divisible by $3$.

     b) $685$

         sum of digit = $19$

        Since , $19$ is not divisible by  $3$ , the number $685$ is not divisible by $3$.

    c) $189$

        sum of digit = $18$

        Since , $18$ is divisible by  $3$ , the number $189$ is divisible by $3$.  

    d) $4375$

        sum of digit = $19$

       Since , $19$ is not divisible by  $3$ , the number $4375$  is not divisible by $3$.

Hence , option c) is correct ,number $189$ is divisible by $3$.
