Two digit means it'll have two numbers, and we already know that one of them is 8, and the other is half of 8. Well half of 8 is 4. So know we know the two digits (8 and 4) so that could be 84 or 48. Well we also know that the number has to be divisible by 8. 84/8=10.5 so that's not it, 48/8=6 that one works perfectly. So the answer is 48 :)
