Hey  Mate,

We all known that Mobile number consists of 10 Digits.

The first four digits of mobile are 9 9 7 9

We need to make a smallest mobile number from 8, 3, 5, 6 and 0.

So, we will take 0 twice. (Because 0 is the smallest number from the following).

So, the Smallest mobile number is 9 9 7 9 0 0 3 5 6 8.

And the Largest mobile number is 9 9 7 9 8 8 6 5 3 0.
