Question

The smallest five-digit number that can be formed with 0, 5, 9, 6, and 3 using each digit only once is.

• A. 30,569
• B. 09,356
• C. 96,530
• D. 03,569

Answer 1

The correct option is A 30,569

Arrange the digits in the increasing order of their values.
0 < 3 < 5 < 6 < 9
Place the smallest digit at the largest place and arrange the remaining digits in an increasing order.
Watch out! 03569 has only four digits since 0 has no value at the beginning of a number!
To form the smallest five-digit number, place 0 in the second highest place.
Thus, the smallest five-digit number that can be formed is 30,569.
