6 years ago from now, ratio of ages of ‘R’ and
‘L’ was 5:7, respectively. If ‘L’ is 6 years elder to ‘R’, then what will be the age of ‘L’, 10 years hence from now?Solution
6 years ago from now, let ages of ‘R’ and ‘L’ be ‘5x’ years and ‘7x’ years, respectively. So, 7x – 5x = 6 Or, 2x = 6 Or, x = 3 Present age of ‘L’ = 7x + 6 = 7 × 3 + 6 = 27 years Age of ‘L’, ten years hence from now = 27 + 10 = 37 years
