Question

Write the greatest and the smallest $6$-digit numbers using all the following digits:

$3,6,0,9,2,5$

Answer 1

For the greatest number, we write the greatest digit $9$ in the Lakh column, the next smaller digit in the T-Thousands column, etc.

Lakh	T-Th	Th	H	T	O
$9$	$6$	$5$	$3$	$2$	$0$

The Greatest $6$-digit number$=965320$

For the smallest number, we write the smallest digit in the Lakh column. But here$0$ is the smallest digit, $0$ which is not written on the extreme left of a number.

So, we write$2$, the next greater number, in the Lakh column and $0$ the T-Thousands column. The next digit is greater than$2$ in the thousands column and so on.

Lakh	T-Th	Th	H	T	O
$2$	$0$	$3$	$5$	$6$	$9$

The Smallest 6-digit number $=20356$

So, the numbers are $965320$ and $203569$
