Problem:
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?
Solution:
Break the 7 piece gold bar to make a piece of 1 segment size and the other of 2 segments size.( the remaining 4 segments intact)
i.e 7= 1 + 2 + 4 (only two breaks needed)
1- 1st day
2- 2nd day
(1+2) - 3rd day
4 - 4th day
(4+1) - 5th day
(4+2) - 6th day
(4+2+1) - 7th day.
