Answer:
Correct option is $6410.96
Explanation:
Let investment in K=$x
Hence investment in L=(12000-x)
Portfolio return=Respective return*Respective weights
9.75=(x/12000*8.05)+(12000-x)/12000*11.7
(9.75*12000)=8.05x+140400-11.7x
117000=8.05x+140400-11.7x
x=(140400-117000)/(11.7-8.05)
=$6410.96(Approx)=investment in K
