example 4. Arrange the following numbers in ascending order:

30,72,249, 18,89,620, 1,21,450, 75,04,545, 83,250

Solution. Let us arrange the given numbers in the place TL L TTh Th H T O
value chart.
3 0 7 2 2 4 9
Here, we can see that there are three 7-digit numbers, 1 8 8 9 6 2 0
one 6-digit number and one 5-digit number.
1 2 1 4 5 0
Clearly, the 5-digit number is the smallest, and the 6-digit

number is greater than the 5-digit number. 7 5 0 4 5 4 5
8 3 2 5 0
In the 7-digit numbers, the ascending order is

18,89,620, 30,72,249, 75,04,545.

So, the numbers in ascending order are:

83,250, 1,21,450, 18,89,620, 30,72,249, 75,04,545

example 5. Arrange the following numbers in descending order:

36,72,906, 46,35,618, 39,10,257, 98,76,879, 46,13,898 TL L TTh Th H T O

Solution. Let us first put the given numbers in the place 3 6 7 2 9 0 6
value chart and then arrange them in descending order 4 6 3 5 6 1 8
accordingly.
3 9 1 0 2 5 7
Hence, the given numbers in descending order are: 9 8 7 6 8 7 9

98,76,879, 46,35,618, 46,13,898, 39,10,257, 36,72,906 4 6 1 3 8 9 8
