The sum of two numbers is 84, and one of them is 12 more than the other. What are the two numbers?
Choose the correct answer
A) 48 , 36  B) 36 , 48  C) 32 , 48  D) 48 , 32  E) 32 , 42

Rationale: 2 x = 84 − 12 = 72 . x = 72 / 2 = 36 . this is the first number . therefore the other number is x + 12 = 36 + 12 = 48 . the sum of 36 + 48 is 84 . answer is b .
Answer: B
