Question: You’ve 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)
Answer : Assume gold bar as currency note with worth of Rs 7. Make two cuts on the gold bar such that these are worth of Rs 1, Rs 2 and Rs 4 respectively.
At each day give this bar as follows:-
- Day 1: Give Bar 1 (You- 2 and 4, Worker- 1)
- Day 2: Give Bar 2, Take back Bar 1 (You- 1 and 4, Worker- 2)
- Day 3: Give Bar 1 (You- 4, Worker- 1 and 2)
- Day 4: Give Bar 4, Take back Bar 1 and Bar 2 (You- 1 and 2, Worker- 4)
- Day 5: Give Bar 1 (You- 2, Worker- 1 and 4)
- Day 6: Give Bar 2, Take back Bar 1 (You- 1, Worker- 2 and 4)
- Day 7: Give Bar 1 (You- Empty, Worker- 1, 2 and 4)
