Question

The smallest $$6$$ digit natural number ending in $$5$$ is _____ .

Answer 1

So, unit place must be $$5$$

To make smallest number we can use all $$0$$ but can't use $$0$$ at $$1^{st}$$ place, otherwise it will become $$1$$ digit number.

Now, $$1^{st}$$ place must be $$1$$ and other digits are $$0$$

$$\therefore$$ The smallest $$6$$ digit natural number ending in $$5$$ is $$100005$$
