Question

Which of the following is divisible by 3?

• A. 1432
• B. 2132
• C. 2331
• D. 1453

Answer 1

The correct option is C 2331

If the sum of the digits of a number is divisible by 3, then the number will be divisible by 3.

1432 $\Rightarrow$ 1 + 4 + 3 + 2 = 10
2132 $\Rightarrow$ 2 + 1 + 3 + 2 = 8
2331 $\Rightarrow$ 2 + 3 + 3 + 1 = 9
1453 $\Rightarrow$ 1 + 4 + 5 + 3 = 13
Here, only 9 is divisible by 3.

$\therefore$ 2331 is divisible by 3.
