Question
The present age of ‘P’ is 40 years, which is 33.33%
more than that of ‘Q’. The average of present ages of ‘Q’ and ‘R’ is 45 years. The ratio of present ages of ‘R’ and ‘S’ is 5:8. Find the difference in present ages of ‘P’ and ‘S’.Solution
ATQ, Present age of ‘Q’ = 40 / (4/3) = 30 years Present age of ‘R’ = (2 × 45) – 30 = 90 – 30 = 60 years Present age of ‘S’ = 60 × (8/5) = 96 years Required difference = 96 – 40 = 56 years
