Question
8 years ago from now, ratio of ages of ‘R’ and
‘L’ was 3:5, respectively. If ‘L’ is 7 years elder to ‘R’, then what will be the age of ‘L’, 2 years hence from now?Solution
8 years ago from now, let ages of ‘R’ and ‘L’ be ‘3x’ years and ‘5x’ years, respectively. So, 5x – 3x = 8 Or, 2x = 8 Or, x = 4 Present age of ‘L’ = 5x + 7 = 5 × 4 + 7 = 27 years Age of ‘L’, two years hence from now = 27 + 2 = 29 years
