Question

Postal Index Number consists of six digits. The first three digits are 6, 3, and 1. Make
the largest and the smallest Postal Index Number by using the digits 0,3 and 6, each
only once.

Answer 1

The first three digits are 6, 3, and 1

So, all the numbers will begin with 631


The other 3 digits are  0,3 and 6


To get the largest Index, we arrange the last 3 digits from the largest to the smallest (630), and the largest Index becomes: 


631630

To get the smallest Index, we arrange the last 3 digits from the smallest to the largest (036), and the smallest Index becomes:


631036
