    Question

    A girl’s age is 130% of what it was 5 years ago,

    but 55% of what it will be after 10 years. What is her present age?
    A 12 years Correct Answer Incorrect Answer
    B 16 years Correct Answer Incorrect Answer
    C 10 years Correct Answer Incorrect Answer
    D 19 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, => 1.3 ×(x-5) = 0.55×(x+10) => 1.3x – 6.5 = 0.55x + 5.5 => 0.75x = 12 => x = 16 years
