Profit

Post by Amaranth »

Cam usoara dar...

Un vanzator vinde un colier (unul foarte ieftin) pentru 100$. El l-a cumparat cu 4/5 (asta ar fi o fractie) din pret. care este profitul? :wink:
In all this world there is only one pure and magic thing... and it is called PURPLE!

100-(100*4:5)=100-(400:5)=100-80=20
