solve two equations on the 2nd case.
1.23 = m (1.775 - F)
1.5 = m ( 2-F)
m = 1.2, F=0.75 is the solution.
Since m = 1.2  1 - it is CPPI
On the first case Stocks / Portfolio = 0.75 constant (=m
This can also be reached by solving
1.5 = m ( 2-F)
1.33125 = m (1.775 - F)
subtracting : 0.16875 = 0.225 m
m = 0.75
F = 0
