Age of Fred now = F
Need to determine F + y
(1) Doris is 12 years older than Fred.
=> D = F+12
=> Cannot know F+y => INSUF
(2) The sum of the ages of Doris and Fred is y years.
=> D + F = y => Cannot not F+y => INSUF
(1)+(2): F+F+12= y
=> INSUFFICIENT
=> Ans: E

VERITAS PREP OFFICIAL SOLUTION:
Question Type: What Is the Value? This question asks how old Fred will be in y years.
Given information from the question stem: This question is asking for a specific number for the age that Fred will be y years from now. You can represent that as F + y.
Statement 1: Doris is 12 years older than Fred can be written “F + 12 = D.” This is clearly not sufficient to determine Fred’s age now or in the future. Eliminate
choices A and D.
Statement 2: The sum of the ages of Doris and Fred is y years can be written “F + D = y.” This statement only consists of three variables without any actual numbers, so it cannot give us a specific age for Doris or for Fred. This is not sufficient, so eliminate choice B.
Together: If you take both statements together you can use the second equation “F+D = y” and substitute “F+12” for D. This yields the equation “F + F + 12 = y.” Without knowing either what y is or what F is this equation cannot be solved, as it is one equation with two variables.
The answer is E.
