Each digit in the two-digit number G is halved to form a new two-digit number H. Which of the following numbers could be the sum of G and H?
Select the correct option: A) 153 B) 150 C) 137 D) 135 E) 89
Let x be the original 2-digit number.   If each digit is halved, then the sum of G and H is 3x/2.   Note the sum must be a multiple of 3 and less than 150.   Only 135 satisfies these two conditions.   The answer is 135.
