When a question includes a word in UPPER CASE LETTERS, reverse the word in upper case letters:
Which of the following COULD be the total weight?
Now find the 4 answers choices that answer the question above. The correct answer will be the remaining answer choice.
A) 9 = 1+3+5
B) 10 = 3+7
C) 12 = 5+7
D) 13 = 1+5+7
Since A, B, C and D could be the total weight, the correct answer is
E. No combination of 1, 3, 5, and 7 will yield a sum of 14.
