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) 143  D) 141  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.   Of these five choices, only 141 satisfies these two conditions.   The answer is 141.
