I need to pay an employee each day for one week. His wages are 1 piece of the 7-segment gold bar per day. How can I cut the bar to allow for fair payment using only 2 cuts. You cannot fold the bar?

If I have 1 gold bar, equally divided into 7 pieces as such:

|=|=|=|=|=|=|=|

I need to pay an employee each day for one week. His wages are 1 piece of the gold bar per day. How can I cut the bar to allow for fair payment using only 2 cuts. You can not fold the bar because it is gold.

And the answer is that that you can get pieces from workers. So, cut like this

|=|

|=|=|

|=|=|=|=|

  • Monday: pay with 1st piece
  • Tuesday: pay with 2nd piece but take back the 1st piece
  • Wednesday: pay with 1st piece
  • Thursday: pay with the 3rd piece but take back the 1st and 2nd piece
  • Friday: pay with 1st piece
  • Saturday: pay with 2nd piece but take back the 1st piece
  • Sunday: pay with 1st piece
