Explain.
_____

Explanation:
Let’s name the digit:
X be one’s digit and y be tens digit
we know that X=Y-2. Now, Y can be 6,7,8,9 the number is between 60 and 100
As the possibilities with x=y-2, the numbers would be 64,75,86,97.
And 64 and 86 are even, so they can’t be prime. 75 is a composite number as there are more than two factors. So the remaining number is 97.
