D. 53
E. 62

Answer: D

Let the two-digit number be xy. Given that x+y=8.
Every option satisfies this condition. So, let’s go to the next piece of information.
If 18 is subtracted from the number, then the digits are interchanged.

i.e. xy-18=yx
We need to check which option will satisfy the above condition. Only option D will satisfy.

Hence, the answer is D.
