Raymond has ask Kenneth, Doris, Bei Yi and me this question just now, which is a quiz that took 2 days for him to figure it out... You can give it a try if anyone is interested. It goes like this:


















In the picture above, there are 3 groups of people, mainly the Policeman and the Thief, a Mother with 2 daughters, and a Father with 2 sons.

The policeman and the thief cannot be seperated. If the policeman is away, the thief would beat the mother and father up and he could escape.

The mother and father can be together but both can not leave their children behind. For instance, if the mother go across to Land B, the daughter will be beaten up by the Father in Land A. Same goes to the sons. This means that the mother would beat up the sons if she sees them in the same land, as well as the father beating up the daughters, unless the respective parent is by their side.

Both daughters and sons do not know how to row the boat. Only the mother, father and policemen knows how to row it.

Your mission is to bring all of them across to Land B. There is a boat in the river and it only allows at most of 2 passengers. Try bringing them over now.

** Enjoy the quiz... I'm still figuring it out...
