I am a 2 digit number the sum of my digits is 15 my t and digit is odd my ones digit is even what number am I

Answer 1

You have a typo, I will assume you meant:
"my tenth digit is odd"

Let the unit digit be x
and the tenth digit be y

x+y = 15
y = 15-x , where x is even
clearly x can only be 8 or 6 to have valid number

The number could be 78 or 96

If you meant otherwise, make the needed changes
