Is there a particular way to solve this type of question?
I could not make a head or a tail of it without the spoiler.
First, I tried to find out the least possible of the difference between the tens of the two 2-digit integers.
I have got two possibilities.
4 - 2 = 2
6 - 4 = 2
Then, I proceeded by iteration.
62 - 49 = 13
The answer is indeed D
