You’ve got someone working for you for seven days and a gold bar to pay them. The gold bar is segmented into seven connected pieces. You must give them a piece of gold at the end of every day. If you are only allowed to make two breaks in the gold bar, how do you pay your worker?

1. Md Abdul Aziz is on the right track…
   Cut it into 3 part where the parts are 1, 2 and 4 segments long.
   Day 1 – Give 1 segment bar
   Day 2 – Give 2 segment bar ask for 1 segment bar back
   Day 3 – Give 1 segment bar
   Day 4 – Give 4 segment bar ask for 1 + 2 back
   Day 5 – Give 1 segment bar
   Day 6 – Give 2 segment bar ask for 1 segment bar back
   Day 7 – Give 1 segment bar
