    D 40 years Correct Answer Incorrect Answer

    Solution

    16 years ago from now, let ages of ‘R’ and ‘L’ be ‘3x’ years and ‘5x’ years, respectively. So, 5x – 3x = 16 Or, 2x = 16 Or, x = 8 Present age of ‘L’ = 5x + 9 = 5 × 8 + 9 = 49 years Age of ‘L’, five years hence from now = 49 + 5 = 54 years
