Question
The ratio of age of βBβ after 3 years from now and
age of βCβ 6 years ago from now is 7:4, respectively. The present age of βCβ is 30% of the present age of βAβ. If present age of βAβ is 60 years then find the present age of βBβ.Solution
Present age of βCβ = 0.3 Γ 60 = 18 years 6 years ago from now, age of βCβ = 18 β 6 = 12 years 3 years hence from now, age of βBβ = 12 Γ (7/4) = 21 years Present age of βBβ = 21 β 3 = 18 years
