Question

Among the following numbers, what is the missing digit which makes the number $653$_ exactly divisible by $5$?

• A. $2$
• B. $4$
• C. $5$
• D. $9$

Answer 1

The correct option is C $5$

We know the divisibility rule for $5$:
Check whether the last two digits ends with $0$ or $5$.
Here, $6532,6534,6539$ are not divisible by $5$.

$6535$ is divisible by $5$, because the last digit ends with $5$.

So, option C is correct.
