    Question

    Currently, the ages of Rahul and Ritesh are in a ratio

    of 7:3. If we look back three years, the ages of Ritesh and Ramesh had a ratio of 1:3. Knowing that Rahul is 6 years younger than Ramesh, can you determine the current average age of Rahul, Ritesh, and Ramesh?
    A 32 years Correct Answer Incorrect Answer
    B 34 years Correct Answer Incorrect Answer
    C 36 years Correct Answer Incorrect Answer
    D 38 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the present ages of Rahul and Ritesh are 7x years and 3x years respectively. Age of Ritesh three years ago = 3x – 3 years Age of Ramesh three years ago = 3 × (3x – 3) = 9x – 9 years Present age of Ramesh = 9x – 9 + 3 = 9x – 6 years According to question: 9x – 6 – 7x = 6 2x = 12 x = 6 So, the present ages of Rahul, Ritesh and Ramesh are 42 years, 18 years and 48, years respectively. Present average age of Rahul, Ritesh and Ramesh = (42 + 18 + 48)/3 = 36 years
