Question
9 years ago from now, ratio of ages of βRβ and
βLβ was 2:5, respectively. If βLβ is 5 years elder to βRβ, then what will be the age of βLβ, 5 years hence from now?Solution
9 years ago from now, let ages of βRβ and βLβ be β2xβ years and β5xβ years, respectively. So, 5x β 2x = 9 Or, 3x = 9 Or, x = 3 Present age of βLβ = 5x + 5 = 5 Γ 3 + 5 = 20 years Age of βLβ, five years hence from now = 20 + 5 = 25 years
