Hi All,
We're told that each DIGIT in the two-digit number G is halved to form a new two-DIGIT number H. We're asked which of the following COULD be the sum of G and H? The phrasing of the question means that there's more than one possible answer, so we have to do enough work to find one of the possible answers among the 5 choices.
This question can actually be solved with just a bit of 'brute force' Arithmetic. If you 'halve' a DIGIT and end up with another DIGIT, then there are only a handful of possibilities to consider:
8 --> 4
6 --> 3
4 --> 2
2 --> 1
0 --> 0
Considering how 'big' most of the answers are, it's highly likely that the first digit of 'G' is an 8 (and the first digit of 'H' would be a 4). At this point, the total of G and H is at least 120. With just a little experimentation, you can get to the correct answer. With 88 and 44, the total would be 132; with 86 and 43, the total would be 129.
