MCQ

Mark the correct alternative in the following: The smallest three digit number having three distinct digits is:

A
$123$
B
$101$
✓
$102$
D
$201$

✓

Answer

Correct option: C.

$102$

The three distinct smallest digits are $0, 1$ and $2$.
To form a smallest number using these digits, we need to arrange them in ascending order, but by this we get $012$, which results in a two-digit number.
So, the smallest three-digit number having distinct digits is $102$.
