Question
16 years ago from now, ratio of ages of βRβ and
βLβ was 3:5, respectively. If βLβ is 9 years elder to βRβ, then what will be the age of βLβ, 5 years hence from now?Solution
16 years ago from now, let ages of βRβ and βLβ be β3xβ years and β5xβ years, respectively. So, 5x β 3x = 16 Or, 2x = 16 Or, x = 8 Present age of βLβ = 5x + 9 = 5 Γ 8 + 9 = 49 years Age of βLβ, five years hence from now = 49 + 5 = 54 years
