If Mason is now twice as old as Gunther was 10 years ago, and G is Gunther's current age in years, which of the following represents the sum of Mason and Gunther's ages 4 years from now?

(A) 3G/2 + 3

(B) 3G + 28

(C) 3G – 12

(D) 8 – G

(E) 14 - 3G/2

Kudos for a correct solution.

Plug in 15 Years for Gunters current Age. If Gunther is 15 Now, 10 Years ago he was 5 and Mason is therefore 10 Today. In 4 years both will be 14 and 19 respectively summing to 33.

Plug in G = 15 in the answer choices and see which AC results in 33.

Answer Choice C
