Question

Determine whether $3725$ is divisible by $5$ or by $10$

Answer 1

Step 1 : Checking divisibility by $10$

Divisibility by $10$ : A number is divisible by $10$ if its last ( unit’s )digit is $0$

$3725$ has $5$ in its unit's place. So, it is not divisible by $10$

Step 2 : Checking divisibility by $5$

Divisibility by 5 : A number is divisible by $5$ if its last ( unit’s ) digit has $0$ or $5$

$3725$ has $5$ in its unit's place . So , it is divisible by $5$.

Hence , $3725$ is divisible by $5$ and not divisible by $10$
