Question
The ratio of ages of P and Q, after 8 years will be
19:14 respectively. The present average age of P, Q and R is 52 years. If present age of R is 25% more than age of P 5 years ago, then find the ratio of present ages of Q and R respectively.Solution
ATQ,
Let ages of P and Q, after 8 years be 19x years and 14x years respectively. Present age of P = β19x β 8β years Present age of Q = β14x β 8β years Present age of R = 52 Γ 3 β (19x β 8 + 14x β 8) = β156 β 33xβ years According to the question: 1.25 Γ (19x β 8 β 5) = 156 β 33x Or, 1.25 Γ (19x β 13) = 156 β 33x Or, 23.75x β 16.25 = 156 β 33x Or, 56.75x = 172.25 Or, x = 3 Present age of Q = 14 Γ 3 β 8 = 34 years Present age of R = 156 β 33 Γ 3 = 57 years Desired Ratio = 34:57 = 2:3
