Portfolio weight B = 0.3128
Step-by-step explanation:
Calculation for What are the portfolio weights
First step is to calculate the Top Value
Top Value = 145(45) + 110(27)
Top Value = 9495
Calculation for Portfolio weight A
Portfolio weight A = 145(45)/9495
Portfolio weight A = 0.6872
Calculation for Portfolio weight B
Portfolio weight B = 110(27)/9495
Portfolio weight B = 0.3128
Therefore the portfolio weights are :
Portfolio weight A = 0.6872
Portfolio weight B = 0.3128
