Which of the following is not divisible by 3?
Correct Answer
D. 25
Explanation
In order to determine if a number is divisible by 3, we can check if the sum of its digits is divisible by 3. If the sum is divisible by 3, then the number itself is divisible by 3. However, if the sum is not divisible by 3, then the number is also not divisible by 3. In this case, the number 25 has a sum of digits equal to 7, which is not divisible by 3. Therefore, 25 is not divisible by 3.
