Question: 1 / 400

Which of the following numbers is divisible by 6?

2205

9080

12960

To determine if a number is divisible by 6, it must meet two criteria: it must be even (divisible by 2) and the sum of its digits must be divisible by 3.

For the number 12960:

- It ends in a 0, which confirms it is even, satisfying the first condition (divisible by 2).

- Adding the digits together: 1 + 2 + 9 + 6 + 0 = 18. Since 18 is divisible by 3, the second condition is also met.

Therefore, 12960 is divisible by both 2 and 3, making it divisible by 6.

The other numbers do not meet these criteria when checked. For instance, 2205 is odd, thus failing the first condition. 9080 is even, but when summing its digits (9 + 0 + 8 + 0 = 17), the result is not divisible by 3. 21850, while even, also does not yield a digit sum that is divisible by 3 (2 + 1 + 8 + 5 + 0 = 16). Thus, 12960 is the only number from the given options that is
