 the smallest 5-digit numbers using different digits in which 5 appears at ten’s place=10,050

Answer 2

For lowest possible value consider 100050.

For Highest Possible Value Consider 99959. This answer appears like a puzzle because the ten’s place of the number should be occupied by the digit 5 in every other numbers.

The lowest possible number is 100050 and the highest possible number is 99959.
