Question

Identify the smallest 3 digit number that can formed using the digits 8, 5 and 1 by taking each digit once.

• A. 851
• B. 158
• C. None of the above
• D. 185

Answer 1

The correct option is B 158

1 < 5 < 8

Hence, the smallest 3 digit number using 8, 5 and 1 by taking each digit once is 158.
