Question

The smallest three-digit number that can be formed using 6, 3 and 8 without repetition is ___ .

Answer 1

When we arrange the given digits in ascending order we get the smallest number possible and when arranged in descending order we get the largest number possible.
Hence, using the digits 6, 3 and 8 the smallest number that can be formed is 368 and the largest will be 863.

[Please note that zero (0) cannot take the leftmost place. If zero is there in the given digits then it will take second place from left and the digit just larger than zero will take the leftmost place to get the smallest number possible]
