    Question

    In the following questions, two equations numbered I and II are given. You have to solve both the equations and find out the correct option. Give answer 

    I. 8/(√x) + 6/(√x) = √x II. y ³-

    (14)7/2 /(√y) = 0
    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. 8/(√x) + 6/(√x) = √ x    ⇒  (8+6)/(√x) = √ x  ⇒ 14/(√x) = √ x ⇒ 14 = x ⇒ x = 14  II. y ³- 〖(14)〗^(7/2)/(√y) = 0  ⇒ y ³ = 〖(14)〗^(7/2)/(√y)   ⇒ 〖(y)〗^(7/2) = 〖(14)〗^(7/2)  ⇒ y = 14 Hence, x = y
