切金問題

一個老闆有一塊７cm 嘅金條，而他有一位臨時工人，工作７天，每天的酬勞是１cm 嘅金。

如果這個老闆只可以在金條上切兩刀，他應該怎樣切，才能夠每天發放相等的酬勞給這位臨時工人？

Cut the 7cm into 1, 2 and 4.
Day1: give the 1 =1
Day2: take back the 1. give the 2 =2
Day3: give the 1 =3
Day4: take back the 1 and 2, give the 4 =4
Day5:  give the 1 = 5
Day6: take back the 1, give the 2 =6
Day7: give the 1. That is all given to him =7.
