Tough River Crossing Riddle
This one is a bit of tricky river crossing puzzle than you might have
solved till now. We have a whole family out on a picnic on one side of
the river. The family includes Mother and Father, two sons, two
daughters, a maid and a dog. The bridge broke down and all they have is a
boat that can take them towards the other side of the river. But there
is a condition with the boat. It can hold just two persons at one time
(count the dog as one person).
No it does not limit to that and there are other complications. The dog
can't be left without the maid or it will bite the family members. The
father can't be left with daughters without the mother and in the same
manner, the mother can't be left alone with the sons without the father.
Also an adult is needed to drive the boat and it can't drive by itself.
How will all of them reach the other side of the river?
