      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
