    Question

    A girl’s age is 125% of what it was 10 years ago, but

    75% of what it will be after 10 years. What is her present age?
    A 40 years Correct Answer Incorrect Answer
    B 36 years Correct Answer Incorrect Answer
    C 30 years Correct Answer Incorrect Answer
    D 21 years Correct Answer Incorrect Answer

    Solution

    Let the girl's present age be 'x' years. According to question, => 1.25 × (x-10) = 0.75 × (x+10) => 1.25x – 12.5 = 0.75x + 7.5 => 0.5x = 20 => x = 40 years
