Question

    I. 15/(√x)+9/(√x)=11√x II.

    (√y)/4 + (5√y)/12 = 1/(√y)
    A If x≥y Correct Answer Incorrect Answer
    B If x≤y 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
