Question

Find the difference between the greatest number and the smallest number formed using the digits 5, 3, 4, and 0 without repetition of digits.

• A. 2385
• B. 2359
• C. 2575
• D. 2526

Answer 1

The correct option is A 2385

If the given digits are arranged in descending order, we get the greatest number.
So, greatest 4-digit number formed using the given digits is 5430.

If the given digits are arranged in ascending order, we get the smallest number but remember 0 can't be placed at leftmost digit as it has no value at that place.

So, 3045 will be the smallest possible number.

The difference between them
= 5430 - 3045
= 2385
