    What is the value of x + y?

    [1] x y = 24.

    [2] x/y = 8/3.

    [2] x/y = 8/3
    .

    stmnt 1- xy=24
    we cannot determine x+y
    Stmnt2 - x/y=8/3
    so x=8y/3
    or x+y=8y/3+y=11y/3
    not sufficient.

    combining both statements even wont result in any specific answer
    SO IMO E
    waiting for the OA and a better expanation!!

    This is right that no statement alone is sufficient here. Let’s take the two together

    Put y = 3 x/8 from [2] in [1], a quadratic in x would be obtained, giving out two results for x; or if you put x = 8 y/3 from [2] in [1], a quadratic in y would be obtained, giving out two results for y. Hence, together too, insufficient

    E is right, is your wait over?
