I have the same number of tens and ones. I am an even number. I have more than 5 ones but less than 8 ones. What number am I?

Answer 1

To be even, the unit digit could be 0, 2, 4, 6, or 8
but the "ones" have to be > 5 and < 8
so it could only be 6

Also the tens and ones are the same.

so it could be 66
or 766, or 897566, or .....
(as long as the condition applies to the tens and ones, you could have
an infinite such numbers)
