Answer 1

G H I J K L
a 18 21 28 5 9 10
b 14 19 8 23 5 -5
c 8 11 14 -3 27 20
d 6 23 19 -1 26 14
e 19 -4 25 25 20 -10
f 1 -10 22 18 -1 7
1) The market is complete.
2) If Sam wants a guaranteed income of 25$. We can create a portfolio
from the six securities to do that. The guaranteed income is possible in
state a. In this case (18+21+28+5+9+10)/21 = 4.39 units of securities H
must you include in the portfolio.
So, the right answer is c) 4.39.
