      Question

      If √y + (1/√y) = 10, then find the value of y +

      (1/y).
      A 96 Correct Answer Incorrect Answer
      B 98 Correct Answer Incorrect Answer
      C 100 Correct Answer Incorrect Answer
      D 102 Correct Answer Incorrect Answer

      Solution

      Given, √y + (1/√y) = 10
      On squaring both the sides,
      So, y + (1/y) + 2 × √y × (1/√y) = 100
      Or, y + (1/y) + 2 = 100
      So, y + (1/y) = 98
