Expected return=risk free rate+beta*(market rate-risk free rate)
J:
15.8=Rf+1.47*(Rm-Rf)
15.8=Rf+1.47Rm-1.47Rf
15.8=1.47Rm-0.47Rf
Rm=(15.8+0.47Rf)/1.47
K:
11.9=Rf+1.05*(Rm-Rf)
11.9=Rf+1.05Rm-1.05Rf
11.9=1.05Rm-0.05Rf
11.9=1.05(15.8+0.47Rf)/1.47-0.05Rf
11.9=11.2857143+0.335714286Rf-0.05Rf
Rf=(11.9-11.2857143)/(0.335714286-0.05)
