    Question

    A girl’s age is 125% of what it was 5 years ago, but 75% of what it will be after 5 years. What is her present age?

    A 23 years Correct Answer Incorrect Answer
    B 26 years Correct Answer Incorrect Answer
    C 20 years Correct Answer Incorrect Answer
    D 29 years Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the girl's present age be 'x' years. According to question, => 1.25 × (x-5) = 0.75 × (x+5) => 1.25x – 6.25 = 0.75x + 3.75 => 0.5x = 10 => x = 20 years
