The present age of ‘T’ is 36 years, which is 50%
more than that of ‘U’. The average of present ages of ‘U’ and ‘V’ is 42 years. The present age ratio of ‘V’ to ‘W’ is 5:6. Find the difference between present ages of ‘T’ and ‘W’.Solution
ATQ, Present age of ‘U’ = 36 / 1.5 = 24 years Present age of ‘V’ = (2 × 42) – 24 = 84 – 24 = 60 years Present age of ‘W’ = 60 × (6/5) = 72 years Required difference = 72 – 36 = 36 years
