Question
The ratio of age of βBβ after 7 years from now and
age of βCβ 4 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 40 years then find the present age of βBβ.Solution
Present age of βCβ = 0.3 Γ 40 = 12 years 4 years ago from now, age of βCβ = 12 β 4 = 8 years 7 years hence from now, age of βBβ = 8 Γ (7/4) = 14 years Present age of βBβ = 14 β 7 = 14 years
