    Question

    A girl’s age is 145% of what it was 8 years ago, but

    65% of what it will be after 8 years. What is her present age?
    A 25 years Correct Answer Incorrect Answer
    B 16 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, => 1.45 × (x-8) = 0.65 × (x+8) => 1.45x – 11.6 = 0.65x + 5.2 => 0.8x = 16.8 => x = 21 years
