The current ages of P and Q are
in the ratio of 8:5. The ratio of P's age seven years ago to Q's age ten years from now is 5:6. What will be P's age 8 years from now?Solution
ATQ, Let the present ages of 'P' and 'Q' be‘8p’ years and ‘5p’ years respectively. According to question, (8p – 7)/(5p + 10) = 5/6 48p – 42 = 2p + 50 23p = 92 p = 4 So, the present age of 'P' = 8 × 4 = 32 years Age of 'P' after eight years = 32 + 8 = 40 years
