Question
Age of βAβ after 12 years will be three time of his
age 20 years ago. Eight years hence from now, ratio of ages of βAβ and βBβ will be 2:3, respectively. If present average age of βAβ, βBβ and βCβ is 40 years, then find the present age of βCβ.Solution
Let present age of βAβ be βaβ years So, 3(a β 20) = a + 8 Or, 3a β 60 = a + 8 Or, 2a = 68 Or, a = 34 Present age of βBβ = 3/2 Γ {34 + 8} β 8 = 63 β 8 = 55 years Present age of βCβ = 40 Γ 3 β 34 β 55 = 31 years
