    Question

    TYPE I

    A girl’s age is 140% of what it was 8 years ago,

    but 60% of what it will be after 8 years. What is her present age?
    A 30 years Correct Answer Incorrect Answer
    B 35 years Correct Answer Incorrect Answer
    C 20 years Correct Answer Incorrect Answer
    D 22 years Correct Answer Incorrect Answer

    Solution

    Let the girl's present age be 'x' years. According to question, => 1.4×(x-8) = 0.6×(x+8) => 1.4x – 11.2 = 0.6x + 4.8 => 0.8x = 16 => x = 20 years
