Question

Form the smallest and the largest $6$-digit numbers using $9,7,3,2,5\&0$only once.

Answer 1

Forming the smallest and the largest $6$-digit numbers using $9,7,3,2,5\&0$only once.

For forming the largest number we put the greatest digit on the extreme left, then decreased the digit on the right side.

So, the largest $6$-digit number $=9,75,320$

Also for forming the smallest number we put the smaller digit on the extreme left, then the increasing digit on the right side. But zero can not be placed on the extreme left because it can not form the six-digit number.

So, the smallest $6$-digit number $=2,03,579$

Hence the largest and the smallest $6$-digit numbers using $9,7,3,2,5\&0$only once are $9,75,320\&2,03,579$ respectively.
