8 years ago from now, ratio of ages of ‘R’ and
‘L’ was 3:7, respectively. If ‘L’ is 8 years elder to ‘R’, then what will be the age of ‘L’, 6 years hence from now?Solution
8 years ago from now, let ages of ‘R’ and ‘L’ be ‘3x’ years and ‘7x’ years, respectively. So, 7x – 3x = 8 Or, 4x = 8 Or, x = 2 Present age of ‘L’ = 7x + 8 = 7× 2 + 8 = 23 years Age of ‘L’, six years hence from now = 23 + 6 = 28 years
