Question

The smallest 5-digit number that can be put together using the digits 3, 9, 0, 4 and 1 is ___.

• A. 10,349
• B. 01,349
• C. 13,049
• D. 10, 439

Answer 1

The correct option is A

10,349

To form the smallest number using the digits 3, 9, 0, 4 and 1 we need to arrange the numbers in ascending order.

0 < 1 < 3 < 4 < 9

One of the given digits is 0 and it is known that we cannot start a 5-digit number with 0 as it will become a 4-digit number, So we add the zero as the second digit in the number.
Hence, the smallest 5 digit number that can be formed using the digits 3, 9, 0, 4 and 1 is 10,349.
