Forming 4-digit Numbers
We can form numbers using the given digits by arranging them in di erent order. For
example, using the digits 6, 3, 8 and 1, the greatest 4-digit number that can be formed
is 8631 and the smallest 4-digit number that can be formed is 1368.
1. To form the greatest 4-digit number, arrange
the given digits in descending order.
2. To form the smallest 4-digit number, arrange
the given digits in ascending order.
Example 10: Write the greatest and the smallest 4-digit number using the digits 2, 9, 0
and 5.
Solution:
The greatest 4-digit number is 9520.
(on arranging the digits in descending order)
The smallest 4-digit number is 2059.
(on arranging the digits in ascending order)
Note that the smallest 4-digit number is 2059 and not 0259 as 0 in the beginning
of a number has no value.
