Question

9316 is divisible by.

• A. 4
• B. 3
• C. 6

Answer 1

The correct option is A 4

Divisibility by 4: If the number formed by last two digits of any number is divisible by 4, then the whole number is divisible by 4.

For 1916, the last two digits are 16.
16 is divisible by 4.
$\therefore$ 1916 is divisible by 4.

Divisibility by 3: If the sum of digits of a number is divisible by 3, then the number is divisible by 3.

For 1916, the sum of digits is 17 which is not divisible by 3. So, 1916 is not divisible by 3.

Divisibility by 6: If a number is divisible by 2 and 3 both, then it divisible by 6.

1916 is divisible by 2, but it is not divisible by 3. So, 1916 is not divisible by 36.
