So, Gigi, suppose Paul had N chickens. Since last night he's having

 

N-4=N/3 chickens, right??

 

This makes [we're solving for N]   N-N/3=4 , then

                                                 2/3*N=4

                                                  N=12/2=6

So, Paul used to have 6 chicken. After the the night there remained i6-4=2, two chickens only. He needs set 16 chickens; that is, he needs more 16-2=14. 14 more chickens to come to make the enterprise operational ...

 

let me know if questions.
