Question

A number is divisible by 3 if the sum of the digits in the number are divisible by 3

• A. True
• B. False

Answer 1

The correct option is A True

Numbers are divisible by $3$ if the sum of all the individual digits is divisible by $3$.

For example, the last sum of the digits of the number $3627$ is $3+6+2+7=18$, and $18$ is divisible by $3$.

Therefore, $3627$ is divisible by $3$.

Hence, the statement a number is divisible by $3$ if the sum of the digits in the number are divisible by $3$ is true.
