Here is the Solution

 

Gold, Gold, Gold...    

You have got someone working for you for seven days and a gold bar to pay them. You must pay the worker for their work 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? (Assuming equal amount of work is done during each day thus requiring equal amount of pay for each day)

SOLUTION : Break the bar into 3 pieces of weight ratio 1:2:4. Referring these bars as 1, 2 and 4, following needs to be done at the end of each day.

At the end of Day 1: Give Bar 1 (You- 2 and 4, Worker- 1) At the end of Day 2: Give Bar 2, Take back Bar 1 (You- 1 and 4, Worker- 2) At the end of Day 3: Give Bar 1 (You- 4, Worker- 1 and 2) At the end of Day 4: Give Bar 4, Take back Bar 1 and Bar 2 (You- 1 and 2, Worker- 4) At the end of Day 5: Give Bar 1 (You- 2, Worker- 1 and 4) At the end of Day 6: Give Bar 2, Take back Bar 1 (You- 1, Worker- 2 and 4) At the end of Day 7: Give Bar 1 (You- Empty, Worker- 1, 2 and 4)
