Find the smallest digit which will replace * in so that it is exactly divided by .
Let us suppose a variable for the *
Now given no. looks like
The divisibility rule of A no. is completely divisible by if the sum of its digits is divisible by .
=
We have to put the smallest value of x in the above expression so that it will be completely divisible by
If we put,
So, the smallest value that replaces * is.
