      By selling a book at some price, Ankita gains 10%. If

      the book is sold at twice the price, then what will be the gain percentage for Ankita?
      A 140% Correct Answer Incorrect Answer
      B 100% Correct Answer Incorrect Answer
      C 120% Correct Answer Incorrect Answer
      D 125% Correct Answer Incorrect Answer

      Solution

      Ankita gains 10% by selling the book at price S. Therefore, S = 1.1x When the book is sold at twice the price, the new selling price is 2S = 2 × 1.1x = 2.2x. The gain is 2.2x - x = 1.2x. The gain percentage is=1.2x/x × 100 = 120% So, the gain percentage when sold at twice the price is 120%.
