Question

Use the given digits without repetition and make the greatest and the smallest 4-digit numbers.
5, 4, 0, 3

Answer 1

For making the greatest four-digit number using the given digits we have to place the digits in descending order.

Since, 5 > 4 > 3 > 0, the greatest four-digit number that can be formed is 5430.

For making the smallest four-digit number using the given digits we have to place the digits in ascending order.

0 < 3 < 4 < 5

But here we cannot start the number with 0 since we are asked to frame a 4-digit number.

So, the smallest four-digit that can be framed using the given digits is 3045.
