Question

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

$7,0,5,8,1,4$

Answer 1

For the greatest number, we write the greatest digit $8$ in the Lakh column, the next smaller digit in the T-Thousands column, etc.

Lakh	T-Th	T	H	T	O
$8$	$7$	$5$	$4$	$1$	$0$

The Greatest $6$-digit number $=$ $875410$

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$1$, the next greater number, in the Lakh column $0$in the T-Thousands column. The next digit is greater than $1$ in the thousands column and so on.

Lakh	T-Th	T	H	T	O
$1$	$0$	$4$	$5$	$7$	$8$

The Smallest $6$-digit number $=$$104578$

So, the numbers are $875410$ and$104578$
