    Question

    The ratio of the present ages of Ginni and Binni is 5:3

    respectively. Ginni is ‘n’ years older than Binni. If after 2 years, the ratio of the ages of Binni to Ginni is 2:3, then find the value of √(n+5).
    A 3 Correct Answer Incorrect Answer
    B 5 Correct Answer Incorrect Answer
    C 4 Correct Answer Incorrect Answer
    D 8 Correct Answer Incorrect Answer
    E 6 Correct Answer Incorrect Answer

    Solution

    Let the present ages of Ginni and Binni be 5x and 3x respectively. Here, n = 5x – 3x = 2x According to the question, => (5x + 2)/(3x + 2) = 3/2 => x = 2 Now, n = 2x = 4 Required value = √(n+5) = √(4+5) = √9 = 3
