Question
The current combined age of Chris, Kane, and Root is 56
years. Root's current age is 20 years. The age ratio between Chris and Kane is 1:2. If Stokes, who is 3 years younger than Chris, is currently X years old, what will be Stokes' age six years from today?Solution
Let the present ages of Chris and Kane be 'a' and '2a' years respectively. So, a + 2a + 20 = 56 Or, 3a = 36 So, 'a' = 12 Present age of Stokes = 12 - 3 = 9 Therefore, age of Stokes six years hence from now = 9 + 6 = 15 years
