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?
G is Gunther's current age. Let Mason's current age be M.
given M = 2(G10). four years from now Mason's age will be = 2(G10) + 4 = 2G16 four years from now Gunther's age will be = G+4
Sum of ages of Mason and Gunther's after 4 years = 2G16+G+4 = 3G12
Ans : C

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

Ig Gunther's age now is G, his age 10 years ago would have been (G10). Mason currently is= 2(G10)= 2G20
Gunther 4 years from now= G+4 Mason 4 years from now= 2G20+4 =2G16
Sum of Mason and Gunther's age= 2G16+G+4 = 3G12
Option C

Kudos for a correct solution. G's current age=G M's current age=2*(G10) Four years from now, ages are G=G+4 M=2*(G10)+4 Sum of their ages=G+4+2G20+4=3G12 Answer C

Kudos for a correct solution. MANHATTAN GMAT OFFICIAL SOLUTION:D and E can be eliminated: Gunther must be at least 10 years old, in order for him to have had a nonnegative age “10 years ago” and in order for Mason to have a nonnegative age now. We can therefore eliminate D and E, as both choices will give a negative result when G > 10. The correct answer is in fact C.

We want to know (M+4) + (G + 4), or M+G+8. We should write M in terms of G. Given that M = 2 (G  10), this expression can be written as M = 2G  20. All that is left is to subsitute back into the original equation. (2G20) + G + 8 = 3G  12 (A) 3G/2 + 3 (B) 3G + 28 (C) 3G – 12 (D) 8 – G (E) 14  3G/2

Kudos for a correct solution. M = 2 x (G10) = 2G  20 (M+4) + (G+4) = (2G  20 + 4) + (G + 4) = 3G  12

Kudos for a correct solution. We can create the equations: M = 2(G  10) M = 2G  20 So the sum of the ages 4 years from now is: 2G  20 + 4 + G + 4 = 3G  12 Answer: C
