Question

Which of the following numbers is divisible by 9?

• A. 96345210
• B. 87941032
• C. 67594310
• D. 8576901

Answer 1

The correct option is D 8576901

If the sum of the digits of a number is divisible by 9, then the number itself is divisible by 9.

96345210
9 + 6 + 3 + 4 + 5 + 2 + 1 + 0 = 30, and 30 is not divisible by 9.
So, 96345210 is not divisible by 9.

87941032
8 + 7 + 9 + 4 + 1 + 0 + 3 + 2 = 34, and 34 is not divisible by 9.
So, 87941032 is not divisible by 9.

67594310
6 + 7 + 5 + 9 + 4 + 3 + 1 + 0 = 35, and 35 is not divisible by 9.
So, 67594310 is not divisible by 9.

8576901
Clearly, 8 + 5 + 7 + 6 + 9 + 0 + 1 = 36, and 36 is divisible by 9.
$\therefore$ 8576901 is divisible by 9.
