    Post Puzzle #448 - The gold chain

    The man needs to create 3 pieces out of 7 links. 1 piece of 4 links, 2nd piece of 2 links and 3rd link of 1 piece.

    Here is the reason why:
    Link A - 1 link
    Link B - 2 Links
    Link C - 4 Links

    Day 1 - Pay with Link A
    Day 2 - Pay with Link B and take back Link A
    Day 3 - Pay with Link A
    Day 4 - Pay with Link C, and take back Link A & B.
    Day 5 - Pay with Link A
    Day 6 - Pay with Link B and take back Link A
    Day 7 - Pay with Link A

    Thus this way by making 3 pieces of 7-link chain, the wealthy man can pay for 7 days worth of work.

    The man needs to make only one cut - on the third link. So he ends up with three pieces: 1 link (the one that was cut), 2 links joined together and 4 links joined together.

    Day 1: give the single cut link
    Day 2: give the piece with 2 links and take back the single link
    Day 3: give the single link
    Day 4: give the piece with 4 links and take back the pieces with 1 and 2 links
    Day 5: give the single link
    Day 6: give the piece with 2 links and take back the single link
    Day 7: give the single link
