Question

Who am I ?

I am divisible by $5$ . I am greater than $400$ but less than $425$ .

Answer 1

The numbers greater than $400$ but less than $425$ and divisible by $5$ are - $405,410,415,420$

Now , the sum of digits of each numbers are

$4+0+5=9$

$4+1+0=5$

$4+1+5=10$

$4+2+0=6$

The numbers $420$ is divisible by $5$ and the sum of digits is $6$.

Hence , the required number is $420$ .
