    The weight of Asset A in the portfolio P is 18.97%. The right answer is a

    Explanation:

    In order to calculate the weight of asset A in the portfolio P, we would have to calculate first the weight of stock A and B as follows:

    Let weight of Asset A is w,

    0.058 = w (0.07) + (1 - w) (0.05)

    0.058 = 0.07w + 0.05 - 0.05w

    w = 40%

    Weight of Stock A = 40%

    Weight of Stock B = 60%

    Therefore Standard Deviation = [ (0.40) 2 (0.30) 2 + (0.60) 2 (0.20) 2 + 2 (0.40) (0.60) (0.30) (0.20) (0.25) ]1/2

    Standard Deviation = 18.97%

    The weight of Asset A in the portfolio P is 18.97%
