Question

Which is the smallest $5$-digit number with ones place as $5$?

Answer 1

Ten Thousand Place	Thousand Place	Hundred's Place	Tens Place	Ones place
1	0	0	0	5

As we know that smallest five digit number is $10000$, but according to question the ones place must be $5$.

So we may obtain such number by adding $5$to $1000$, i.e. $1000+5$

So , the smallest $5$ digit number with ones place as $5$ is $1005$.
