      Question

      I. 15/(√x)+9/(√x)=11√x II.

      (√y)/4 + (5√y)/12 = 1/(√y)
      A If xтЙеy Correct Answer Incorrect Answer
      B If xтЙдy Correct Answer Incorrect Answer
      C If x>y Correct Answer Incorrect Answer
      D If x Correct Answer Incorrect Answer
      E If x=y or relationship between x and y cannot be established. Correct Answer Incorrect Answer

      Solution

      I. (15 + 9)/(√x) =11√x 24/(√x) = 11√x ⇒ 24 = 11x ⇒ x = 24/11 II. (3√y + 5√y)/12 = 1/(√y) (8√y)/12 = 1/(√y) ⇒ 8y = 12 ⇒ y = 12/8 Hence, x > y
