Economic system Q is given by

also 
if 



substitute these values




differentiate w.r.t to L to get 



1/2 (One and a half) since 12 and 12 are even and there would be a fifty fifty chance of getting one or the other or two of the same.
So 2 divded into 23 parts =2/23 which is simplest form
so each person will recieve 2/23 of a cake
