Urgently provide the solution for below

You are given the following data for two risk factors (1 and 2) and three securities (X and Y and Z):

l0	0.16
l1	0.08
l2	0.11
bX1	1.4
bX2	0.9
bY1	0.85
bY2	0.72
bz1	0.54
bz2	0.43

Now answer the following questions:

Based on the APT model, compute the expected return for X,y,z

Also calculate the expected price of x y z one year from now given that X, Y and Z are all currently priced at 42 and will not pay a dividend in current year.
