    1. Best Answer

      Let present age of granddaughter be x years.
      Therefore, Grandfather’s age = 10x years
      According to question,
      10x=x+54
      ⇒ 10x-x+54
      ⇒ 9x=54
      ⇒ x=54/9=6years
      Hence, granddaughter’s age = 6 years and grandfather’s age = 10 x 6 = 60 years.
