Question

How many of the following numbers are divisible by $6$?
$12,36,45,51,78,96,57$

• A. $4$
• B. $3$
• C. $2$
• D. $1$

Answer 1

The correct option is A $4$

We know the divisibility rule for $6$:
If the number is exactly divisible by both $2$ and $3$, then the given number is also divisible by $6$.
Here, $12,36,78$ and $96$ are divisible by $6$, because the last digit ends with even number and sum of numbers are multiples of $3$.
Therefore, there are $4$ numbers which are divisible by $6$.

So, option A is correct.
