Each digit in the two-digit number G is halved to form a new two-digit number H. Which of the following could be the sum of G and H
Choose the most appropriate option
A) 153  B) 150  C) 137  D) 123  E) 89
let the number be x, now x is halved =&gt; x/2..the question asks what is x?   x(number) + x/2 (half of that number) = something   =&gt; 3x/2 = something   =&gt; x = 2 (something) / 3   so the answer choice must be divisible by 3   eliminate C, E right away   check the rest   D satisfies   3x/ 2 = 123   =&gt; x = 82   Verify. 82 + 41 = 123   Answer is 123
