Question

Select the smallest 3-digit number formed using the digits 4, 1, and 8 without repetition.

• A. $148$
• B. $128$
• C. $184$
• D. $418$

Answer 1

The correct option is A $148$

Numbers formed using the digits 3, 9, and 5 without repetition $-148,184,418,481,814,841$

To find the smallest number, let’s arrange numbers in ascending order, i.e., from the smallest to greatest.

148 < 184 < 418 < 481 < 814 < 841

Hence, option C is correct.
